The PFSQ20-03-G01 by ThorLabs is a top-quality protected aluminum mirror designed for use in laboratory, industrial, and general broadband applications. This mirror boasts a highly durable SiO2 coating that offers maximum protection to the delicate aluminum coating, making it ideal for a wide range of uses. The PFSQ20-03-G01 offers an exceptional average reflectance of over 90% in the spectral range of 450 nm to 2 µm and more than 95% in the spectral range of 2 to 20 µm.

The protected aluminum coating on the PFSQ20-03-G01 is less likely to tarnish than protected silver when used in high humidity environments, and provides a reflectance that is similar to a bare aluminum coating reflectance. Measuring 2” x 2”, the square shape of this mirror and its compact dimensions make it easy to use and store in any laboratory or industrial setting. In addition, the PFSQ20-03-G01 has a surface flatness of λ/8 and a surface quality of 40-20 scratch-dig, which means that that user can rely on it to provide highly precise and accurate results for each use.
