Economy Front Surface Mirrors with Protected Metallic Coatings
  • This variation of our protected silver coating is only found on the PFR14-P02 Rectangular Mirror.

Our protected aluminum, silver, and gold coatings exhibit exceptional broadband reflectance and are practical for many applications that are insensitive to the wavefront of a beam. Other typical uses for these mirrors include single-use applications where the experiment itself damages the mirror. A variety of diameters and square sizes are offered, including an 8" x 8" protected aluminum version. Please see the Specs tab for more details on these mirrors.

According to the spec sheet for ME2-M01 the clear aperture is >90% x 50mmØ = >45mm. At 'worst' this corresponds to 81% of the total area. Ignoring the surface quality specification (as this is for an illumination application) what diameter is actually gold coated? Thanks.
YLohia  (posted 2019-10-04 11:50:36.0)
Hello, thank you for contacting Thorlabs. These mirrors are coated out to the edge. That being said, we only guarantee the specs within the clear aperture and we do not recommend using the regions outside.

Hi, I am Jiang from China, I have a question about ME8S-G01. My question is: how to mount this ME8S-G01 mirror on the optical breadboard, I am not found the mirror mount about this module. Thank you, Form CNITHCH, CAS, CHINA. Best, Jiang B
YLohia  (posted 2019-08-14 10:30:01.0)
Hello Jiang, thank you for contacting Thorlabs. The following mounts can be used for the ME8S-G01: SFH3, SFH2, LFFM1 with B3C, FP02, and CH2B with additional ER rods.

tfrisch  (posted 2016-09-15 04:44:56.0)
Hello, thank you for contacting Thorlabs. SiO2 is the top layer. I do not recommend removing coatings from optics in any case, however.

Good day, Would it be possible to get some of the economy mirrors such as ME05S-G01 in partial reflective coatings to use as an output coupler?
besembeson  (posted 2016-03-04 10:10:56.0)
Response from Bweh at Thorlabs USA. Possibly. I would need to know the reflection/transmission characteristics for your application to determine this. Please contact me at techsupport@thorlabs.com.
user  (posted 2015-11-18 19:05:17.22)
Can You provide data of the complex (n and k) refractive index of the silver mirrors, e.g. compared to the surface of a pure bulk silver ?
besembeson  (posted 2015-11-19 01:27:34.0)
Response from Bweh at Thorlabs USA: This is not information that we provide at this time.
mtaormin  (posted 2015-07-20 18:39:46.437)
(Technical inquiry) I am curious about intentional damage of economy mirrors - would it be feasible to use a laser cutter (~40W infrared) to produce an optical mask by burning off the aluminum coating of a mirror? I suppose the real question is about the damaged portions of the mirror from your tests. Is there a reasonably clean and clear surface left, or is the glass damaged by local heating when the coating is burned off? I think this would be a very useful technique to easily produce custom masks, e.g. annular slits to produce Bessel beams. If an engineer at Thorlabs has any thoughts on this, I would be very pleased to hear them!
besembeson  (posted 2015-09-23 01:45:03.0)
Response from Bweh at Thorlabs USA: In principle, this is possible but will require more extensive studies that we haven't done. When we do our laser damage tests, we expose the optic at multiple points and later examine the optic with a microscope (~100X magnification) for any visible damage. The focus is on the damage only, and not the nature of the spot so we can't comment on the nature of the masks created. We have a picture online with an optic from such a damage threshold test at the following link, under tab "Damage Thresholds" http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=890

Hello! Can you tell me please what is the thickness of gold layer on these mirrors and on mirrors PF10-03-M01? It is same on all such products?
jlow  (posted 2014-07-17 09:53:36.0)
Response from Jeremy at Thorlabs: We cannot give out exact values. The gold layer on the mirror is typically <1µm.
daaavde  (posted 2013-12-22 11:34:28.483)
The data you supply for the products ME1S-G01, ME1S-M01, ME1S-P01 shows reflectance at 12° and 45°. Is it possible to have data for diffuse reflection? (if not, is it possible to have data for other angles other than 12° and 45°?) Best regards, Davide Porzio
tcohen  (posted 2014-01-02 03:58:53.0)
Response from Tim at Thorlabs: We can provide data at other angles of incidence. Are you more interested in total diffuse reflection or scatter as a function of angle of incidence? We can measure this. I’ve emailed you to discuss your preference.

Round Protected Aluminum Mirrors: 450 nm - 20 µm

Our round protected aluminum mirrors are available in Ø1/2", Ø1", and Ø2" sizes, and exhibit average reflectance in excess of 90% in the 450 nm to 2 µm range and 95% in the 2 µm to 20 µm range. A protective SiO2 overcoat is layered over bare aluminum, creating an oxidation-resistant surface which has a smaller chance of tarnishing than protected silver in a high humidity environment.

The graph to the right shows these mirrors' reflectance at a 45° angle of incidence (AOI). The shaded region denotes the spectral range over which we recommend using these optics. See the Graphs tab above for 12° AOI data.

Round Protected Silver Mirrors: 450 nm - 20 µm

Our round silver-coated mirrors are available in 1/2", 1", and 2" diameters and have the highest reflectance of all metal-coated mirrors for the visible wavelength range. Silver is an ideal choice for high reflectance from 450 nm to 20 µm. In order to protect the mirrors from oxidation, they have an overcoat of SiO2. Though the overcoat helps to protect silver from tarnishing, high humidity environments should be avoided.

The graph to the right shows these mirrors' reflectance at a 45° angle of incidence (AOI). The shaded region denotes the spectral range over which we recommend using these optics. See the Graphs tab above for 12° AOI data.
