Thorlabs offers standard two-adjuster kinematic mirror mounts for Ø7 mm, Ø10 mm, Ø1/2", Ø1", or Ø2" optics. These mounts offer an angular adjustment range of ±4° (±3° for the KM200 and KM200CP), are all mountable in left- or right-handed orientations, and secure the mirror at three points using a nylon-tipped locking screw and a double-bored mounting hole. The knobs on the Ø1" and Ø2" mounts are removable, thereby exposing the hex sockets at the end of the lead screws (see the video to the right).
Mounts that center the front surface of a mirror over the center of the mounting post are also available. This design allows a beam incident at 45° to be easily aligned with an optical table's hole matrix.
For your convenience, the popular KM100 and KM200 mounts can be purchased prepackaged with one of our broadband dielectric-coated mirrors at a discount to the individual component prices; please see the product listings below for the available selection. More information regarding the general specifications and the reflectivity of each coating across its spectral range is available under the Mirror Info tab above.
Thorlabs offers a variety of other two and three adjuster mirror mounts, including SM-threaded mounts and our high-stability Polaris™ Mirror Mounts.
A complete presentation of the available information on the broadband dielectric coated mirrors that come premounted in the KM series of kinematic mirror mounts can be seen by following this link. However, the general specifications, spectral operating range, and the reflectivity as a function of wavelength for an unpolarized beam incident at 45° is shown below.

(posted 2019-03-31 11:55:15.48) Hi, for KM100, where is axis of rotation/tilt ? YLohia
(posted 2019-04-01 11:52:41.0) Hello, thank you for contacting Thorlabs. The KM100 rotates about the ball bearing in the corner of the mount with no adjuster. I have reached out to you with a drawing to make this a little clearer. user
(posted 2019-03-22 15:04:06.97) The description and images for this part indicates the two post mounting holes are tapped/threaded, yet the PDF drawing file indicates that the holes are thru. The KM05T properly indicates that the holes are #8-32 tapped.
I anticipated that the holes would be thru (which I can ream out), however, I suggest that you update the drawing text to reflect the fact that the post mounting holes are in fact tapped and not thru. llamb
(posted 2019-03-22 03:37:05.0) Thank you for your feedback. The PDF drawing for the KM05 calls out an "8-32 MOUNTING HOLE THRU". We intended this to explain that the KM05 features an #8-32 thread (as opposed to a smooth or counterbored hole) that goes through the entire thickness of the back plate, as opposed to a blind thread with a limited thread depth. This has been forwarded to our marketing team for further review to help clarify the product specifications. werner.engel
(posted 2018-11-10 13:09:19.26) Hallo! Ich bin gerade dabei, für einen Antrag ein optisches Setup zu erstellen. Dabei wäre es extrem gut, nach dem Zeichnen der Anlage, gleich eine Stückliste mit Preisen zu bekommen. Und wenn das Ganze in 3D wäre, könnte ich auch gleich alle optomechanical parts dazu bestellen.
Ist schon mal an eine eigene 3D-Software
gedacht worden mit der man so ein Experiment zeichnen kann - und auch optisch ansprechend darstellen kann?

(posted 2018-11-21 03:56:52.0) Thank you very much for your inquiry and your suggestion. Yes, we have already discussed such an option internally. However, there are solutions that already offer this feature: Autodesk Fusion 360 or FreeCAD with a plugin called assembly2. Of course, these possibilities do not offer an order option.

(posted 2018-05-04 10:38:58.05) I recently designed a system to use Thorlabs KM05 mounts that my company purchased a few years ago. I just learned that the thickness of the base of these older mounts (0.408") is greater than the thickness listed on the current Thorlabs print for the KM05 (0.31"). However, an even older Thorlabs mount in our possession (a KM05FR) does have the "newer" thinner base thickness (0.31"). Therefore, before I order replacement KM05's to go into my custom hardware, could you please confirm the thickness of the mounting base of the KM05 currently sold by Thorlabs? Again, the old thickness was 0.408", and the new thickness is reported to be 0.31". Thank you. YLohia
(posted 2018-05-04 02:12:30.0) Hello, thank you for contacting Thorlabs. Yes, to confirm, the current thickness is indeed 0.31". user
(posted 2016-03-01 17:15:43.513) We wants to think of KM05CP for our application,but what would be max AOI for the mount? We are concerned that beam is clipped by edge of the mount... besembeson
(posted 2016-03-02 03:48:56.0) Response from Bweh at Thorlabs USA: This should be ~72deg. rjh1205
(posted 2014-06-05 10:03:00.437) Hi. I am using KM 100 with mirror now, and I just wonder how much tilted by turning the adjuster. Is there any data about this? Thanks. besembeson
(posted 2014-06-05 06:10:01.0) A response from Bweh E at Thorlabs Newton-USA: This can be tilted up to +/- 4deg. The resolution is 0.5deg per revolution for the 80 TPI precision adjusters.
If you have a special requirement based on your application, let me know and I will look into this for you please. takeshi.matsuoka1
(posted 2014-01-10 14:06:39.063) Could you add a vacuum compatible version to your product line? The specification is,
2. made by Al
3. UNANOSDIZED Al
4. no brass
5. All parts is cleaned in acetone with an
ultrasonic washing machine before assembling.
6. use vacuum compatible grease cdaly
(posted 2014-01-16 08:04:20.0) Response from Chris at Thorlabs: Thank you for your inquiry. We will be implementing quite a few vacuum compatible, unanodized parts to our standard catalog offerings int he following months, including a version of the 3 axis kinematic mount KS1 (KS1V). The 2 inch mounts KS2 and KM200 are not among the list of avacuum compatible parts scheduled to be released, but we can still offer a version as a custom. We will contact you directly to discuss this further. tcohen
(posted 2012-04-02 09:59:00.0) A response from Tim at Thorlabs: We have already generated data on both the KS and the Polaris and there is a clear difference between the two in terms of returning to original position after temperature cycling. You are certainly right that this information will be useful for selecting between our mounts. We are currently working towards accumulating more data and integrating it into our web presentation and we look forward to having this data available for our customers soon! user
(posted 2012-03-31 18:55:40.0) A response to Tim at Thor Labs- Yes exactly, this is what I was requesting. I don't mind helping you improve your website because it ultimately helps me too and, trust me, there are a lot of other people who would like to have this too. It is much easier to select a mount if all the information is available. Please remember to do both the KS1 and the KM100. If you have more time you might as well do the larger mounts too. PS. I am not a Thor Labs Employee regardless of what everyone is thinking but I do know Alex, John and Brian from the good old days.... tcohen
(posted 2012-03-22 09:42:00.0) Response from Tim at Thorlabs: Thank you for helping us improve our web presentation! We are currently testing the thermal stability of the KM series to help distinguish between our KM and Polaris mounts. We will post an update shortly with the data. In the meantime if you would like to discuss your application or the products in further detail, please feel free to contact us at techsupport@thorlabs.com. user
(posted 2012-03-21 18:27:09.0) Hello Buki what I was really asking about is if you can post on your website, thermal test data on the KM100 and KS1. it would be helpful for comparing with the steel mount called Polaris. bdada
(posted 2012-03-21 18:38:00.0) Response from Buki at Thorlabs:
Thank you for your feedback. It seems you are comparing the KM series mount to the Polaris. Please use the link below and refer to the "Test Data" tab to see the results of the temperature cycling test.
http://thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=3912&pn=POLARIS-K05#5462
We would like to discuss your application further so we can ensure you select the appropriate optical mount. Please contact TechSupport@thorlabs.com to continue this discussion. user
(posted 2012-03-21 01:28:57.0) I like this mount but would like if you could add the thermal test you did on your steel mount so I can compare. It seems as though this mount is just as stable as the steel mount and I can buy 3 for the price of 1 steel mount. Please prove me wrong by showing the test data. jjurado
(posted 2011-05-31 11:27:00.0) Response from Javier at Thorlabs to sshosseini: Thank you very much for your feedback. We will review the design of our kinematic mirror holders and will keep you updated of any changes. sshosseini
(posted 2011-05-20 17:24:50.0) Hi,
I use the 1" and 2" mirror mounts as lens mounts most times. It is perfect and I can adjust my lenses using the nubs. But since the post holder on the mount is not "exactly" in the center of the opening, i need to combine the a BA1 underneath the post so i can adjust the post just a tiny bet. Again, the difference is a tiny bet but it is important when aligning the lens and It would be helpful if you change the design and have the post screw clearance "exactly" in the center of the opening.

(posted 2010-12-10 18:12:55.0) I agree with Isandstrom - removable knobs on the KM05 would be very useful. klee
(posted 2009-09-29 18:03:44.0) A response from Ken at Thorlabs to diogenes500: Thank you for your feedback. Your suggestion has been forwarded to our engineering department for consideration. diogenes500
(posted 2009-09-28 19:06:02.0) It would be nice if there were markers on the outer edges of the km100 which denoted the middle position of the mirror (horizontal and vertical). When I am measuring with a ruler on an optical table it is difficult to gauge where the mirror center is, and this would help a good deal. Laurie
(posted 2008-04-22 16:46:18.0) Response from Laurie @ Thorlabs to lsandstrom: After looking into your suggestion a bit further, it would be possible for us to meet your needs through a special request. The KM05 that you inquired about has 3/16"-100 adjusters as does our KMS. Therefore, we could replace the adjusters on our KM05 with the longer adjusters and removable knobs from the KMS. If you would be interested in such an item, please contact our technical support staff at 973-300-3000. Laurie
(posted 2008-04-21 12:00:57.0) Response from Laurie at Thorlabs to lsandstrom: Thank you for your suggestion concerning removable knobs for our KM05 mounts. I will pass this information on to our mechanics group so that they can consider implementing it in the future. Thanks again for taking the time to provide feedback about how to improve our product line to serve you better. lsandstrom

2nd try...
Please add reflectivity curves to the presentation and consider adding both a "Mirror Specifications" tab as well as a link to the full presentaion on th mirrors.
Also the Related Items tab should show all the other mirror mounts the Thorlabs offers, right i notic that the GM100 and VM1 are missing. |

The KM200CP(/M) Ø2" Kinematic Mirror Mount is designed to center the front surface of a mirror over the center of the mounting post. The mount can be attached to either a Ø1/2" Post or Ø1" Post with an 8-32 (M4) tap. If the mirror's front surface is aligned over one of the breadboard's holes, a beam incident at 45° can be easily aligned with the table's hole matrix. The mount is attached to the post via one of two tapped holes, which allow for right- or left-handed adjuster orientation.
The unique design of the KM200CP(/M) incorporates the post-mounting feature into the fixed, rear plate of the mount, which is also where the brass bushings are found. By having the bushings in the fixed plate, as opposed to the movable plate, the instability of the mount is greatly reduced during adjustments.
As with our standard KM200 mount, our post-centering mount is designed with two 1/4"-80 adjusters that yield ±3° of angular adjustment, and a resolution of 5 mrad (0.3°) per revolution. An optional accessory, the LN2580 bronze locking nut, is available to lock the adjusters once the desired position is reached. The mirror is locked in place with a nylon-tipped locking screw that can be tightened with a 5/64" hex key or balldriver. While our standard KM200 mount centers the optic 1.56" (39.6 mm) above the post, the KM200CP(/M) centers the optic 1.85" (47.0 mm) above the post due to the design of the post mounting feature.
The KMCP adapter can also be used to center our standard KM200 mount over the center of a post.

Hex Key Thumbscrews allow for quick, low-profile adjustment of hex-driven actuators, cap screws, and setscrews. Unlike balldrivers, they can be left in the screw's hex socket between adjustments for convenience. The 0.050" size is especially useful for adjusting our imperial, hex-driven, mini-series kinematic mirror mounts, sold above, as well as any 4-40-sized screws, such as the setscrews on our 30 mm cage plates.
Additional hex key thumbscrews are available in sizes from 1/8" to 3/16" and 2 mm to 5 mm.

These 5/64" Hex Key Adjuster Thumbscrews allow for quick adjustment of many 5/64" and 2 mm hex-driven actuators (or standard actuators with the knobs removed). These temporary knobs can be left in the screw's hex socket between adjustments for convenience (see photo to the right). An 8-32 setscrew (5/64" hex) secures the replaceable hex bit, which can be reversed if the tip is stripped. Contact Tech Support to order replacement hex key bits.
We offer hex key thumbscrews in sizes from 0.050" to 3/16" and 2 mm to 5 mm.
