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.

(posted 2024-02-29 19:10:02.67) Hello,
Please advise if you have more detailed information on:
1) the graph of the reflectance spectra comparison between a protected silver mirror (like ME2S-P01) and a mid-infrared enhanced mirror (like PFSQ20-03-M02).
2) Can both mirrors be cleaned in the lab?
3) Which of these two mirrors is more robust to scratches?
Thank you so much in advance,
Tatiana ksosnowski
(posted 2024-03-07 12:02:36.0) Hello Tatiana, thanks for reaching out to Thorlabs. The reflectance graphs and raw data for each coating can be found on the respective mirror pages. Both mirrors can be cleaned in lab, with the protected silver mirror it is advised to avoid exposure to water and use other solvents instead, and any loose debris should be removed by air dusting first if possible to avoid scratches during cleaning. There is a link above to our Optics Handling and Care Tutorial for additional detail. Neither of these mirrors are scratch-proof. The silver mirror does have a thin SiO2 overcoat layer however this is meant as protection from oxidation/moisture, not for abrasion. The MIR gold mirror does not have any protective layer since it is not as chemically reactive as silver. I have reached out directly to discuss your application in further detail. Michael Barth

Except that, I prefer to know what device do you used to measure the spectral reflectance at fixed AOI?

(posted 2020-03-11 01:09:05.0) Hello S. G., thank you for contacting Thorlabs. The parallelism of these mirrors is < 3 arc min. David Gherardi
(posted 2019-10-04 10:15:28.877) 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. Jiang Bo

(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 iu

Figure G1.1 Protected Aluminum Coating Reflectance Plot
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 mirror surface can be cleaned using a wipe or swab soaked in methanol. For more on cleaning optics, see our optics handling and cleaning tutorial.
Figure G1.1 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.

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.
