Optical mirrors are used in optical instruments to reflect light directed by highly polished, curved or flat glass surfaces. These are treated with reflective optical coating materials such as aluminum, silver and gold.
Optical mirror substrates are made of low expansion glass, depending on the quality required, including borosilicate, float glass, BK7 (borosilicate glass), fused silica, and Zerodur.
All of these optical mirror materials can have enhanced reflective properties through dielectric materials. Surface protection can be applied to ensure resistance to environmental conditions.
Optical mirrors cover the ultraviolet (UV) to far infrared (IR) spectrum. Mirrors are commonly used in illumination, interferometry, imaging, life sciences and metrology. A range of laser mirrors are optimized for precise wavelengths with increased damage thresholds for the most demanding applications.
