This page features Thorlabs' 6-axis kinematic optic mount and prism mounting accessories. The K6X 6-axis kinematic optic mount is designed as a general purpose, high precision positioner and features an SM1 (1.035"-40) threaded bore for mounting Ø1" optics. The K6A1 (K6A1/M) prism mounting attachment is designed to provide a 0.5" x 1.44" platform mounted to the rotation stage of the K6X. More details for each product are given below.

Smart Pack

Minimize CO₂ Footprint
Reduce Non-Recyclable Packing Materials
Improve Packaging Integrity
Saves on Shipping Costs

Thorlabs' Green Initiative is aimed at reducing waste. To that end, we have begun to re-engineer our product packaging. The K6X is now shipped in re-engineered packaging that minimizes the use of non-recyclable materials.

Over the course of a year, the re-engineered packaging across our product line is projected to reduce our CO₂ footprint by more than 16,184 kg and reduce packaging by over 13,893 pounds! As we move through our product line, we will label re-engineered packages with our green Smart Pack sticker (above).

Response from Thorlabs: There should always be some clearance between the mount and the circular bore. I will get in contact with you directly regarding sending your K6X back to us to be inspected/repaired.

It seems like the xy translation is limited because of the circular opening surrounding the inner mount. I often bump into edges when trying to align a fiber. Any thoughts on changing to a square shape so that we can reach the corners? Thanks!

Update from Tim at Thorlabs: There is a possibility of rotation to occur when the X and Y axis is adjusted. We are testing the current K6X to determine where the rotation is coming from and how to redesign to correct for this. Thank you for your feedback to help us create a better product for future users!

Terrible mount, the rotation DOF creeps. If you mount an optical fiber + collimator to this mount, the rotational DOF about the collimator optical axis creeps because of little friction. You cannot maintain any alignment, forget about polarization orientation. Increasing the friction will not fix the problem. Unless you fix this issue by adding a lock screw you should recall this product.

Response from Buki at Thorlabs: Thank you for your response. You cannot lock the rotation of the K6X. Please use the link below to consider some of our lockable rotation mounts: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1885 Depending on your application, we may be able to combine multiple products to get you the rotation and kinematic adjustment you need. We will contact you to continue this discussion.

Hi, Is it possible to lock the rotation of the k6x? thank you

Response from Buki at Thorlabs: Thank you so much for your feedback. We apologize you could not quickly find all relevant information about the K6X. The SM1 thread is 1.035"-40. This information is on the drawing but we are already working on including this information in the web presentation on this page and across our website to make it easier to identify the Thorlabs threads we use. Thank you again for your feedback. We have contacted you to provide additional support, but please contact TechSupport@thorlabs.com if you have any questions.

Terrible. I spent hours both with catalogue and with your website trying to understand what is the thread of this mount (not a thread for mounting on post): the thread to mount optical components with it. Still I do not see any clear number.

Response from Buki at Thorlabs: Thank you for your feedback. We just released XY cage translators that provide translation without the optic cell rotating. Please refer to the link below to get more information about the CXY1 and CXY2. We are working on incorporating this design into the rest of our lens translators. Please contact TechSupport@thorlabs if you have any questions. http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=184&pn=CXY1#3042

Response from Javier at Thorlabs to schaefer: The tip and tilt capability of the K6X mount should help in increasing the coupling efficiency of your system. However, there are other parameters that are also important such as the operating wavelength, the type of fiber used with the F810SMA-780, and the mechanics used to mount this fixed collimator. I will contact you directly to get more information about your experimental setup.

Hi, I use a HPSC10 fiber in combination with the reflective collimator (RC08FC-P01) to create a ray of light with very low divergence. The collimator is mounted on a 60mm cage (using CP1XY and an adapter from 30 ro 60mm cage). Can I use K6X to align the collimator in order to use F810SMA-780 to couple the light back into a fiber? It seems as if the thread of CP1XY isnt precise enough to allign the ray.

I need to connect flexible drive shafts to the X,Y, Pitch and Yaw adjustment screws heads. What is the OD of the X-Y adjustment screw heads and the OD of the pitch and yaw adjustment screw heads? Thanks.

A response from Tor at Thorlabs to rbjaculbia: Thank you for your inquiry. Our Mechanics Department indicates that translation in the x- and y-axes will introduce ~2° of rotation. Please note that this can be easily corrected after adjustments in x- and y-axes are made.

hi, how much rotation does the k6x introduce to the optic? Thanks

A response from Adam at Thorlabs to blair: The weight of the K6X is 1lbs. At this time, we do not offer a cheaper four axis kinematic mount. Thank you for the idea and I will contact you directly to get more information about the price you were looking for.

Hello, I couldnt find the weight of your unit. We want to use it on a motorized stage and interested in the weight due to limits of our stage. Also, do you offer a cheaper four-axis mount? I just want tilt and XY.

A response from Greg at Thorlabs to marshabr: Thank you for your feedback regarding our products. We always like to hear our customers suggestions as customer centricity is at the heart of our company. I am sorry that our K6X mount is not suitable for your application. If you would like, I can have a member of our RMA staff issue a return on these for you. I will also let our Mechanics department that customers, like you, require a 6-Axis mount with completely independent axis adjustment. I updated the webpage to reflect the X- and Y-axis issue you mention.

I purchased two of the K6X mounts. They are not usable for my application because the translation mechanism is inherently coupled to rotation due to the design. When the positioner translates, the moving part pivots about the spring and visibly rotates, meaning that alignment will have to be iterative. This is a very poor design for translation, but it is simple and cheap. I will have to purchase from another vendor that makes a similar device with a good translation stage. I will have to find a use for these mounts in a less demanding application. You really should point out this problem in the description.

A response from Tyler at Thorlabs to jian.wang: Your idea has been entered into our internal engineering forum along with your contact information. Although not all ideas entered into the forum make it to the development stage, we always appreciate suggestions that come from the field. I will personally solicit the attention of an engineer to look at this idea. If the idea is adopted, we traditionally involve the originator of the the idea in the design stage as well provide them with preproduction models, in so much as they want to be involved. Thank you for your contribution.

Dear Sir/Madam It would be a popular good source or detector mount for your cage system, if a cage system compatible new product of functions similar to the "K6X 6-Axis Kinematic Optic Mount" can be made availabe. Regards Dr. J Wang ASG,NPL,UK

A response from Tyler at Thorlabs to r96222041: This depends somewhat on how the device is mounted. However, we tested a K6X by hanging a mass 25 mm off of the front plate of the K6X. The mount functioned correctly for masses up to 330 grams. For heavier masses the springs were not stiff enough for the mount to function properly. We are always interested in hearing about the types of products our customers need for their applications. If you could provide us with more information about your application perhaps we could suggest an alternative solution or develop a product that would be suitable for your needs. Thank you for your interest in our products.

I was wondering that how much weight can this K6X mount support? I want to mount a 700-gram device on it and I am afraid that is too much for this mount. Thanks for your reply.
