Product Family Description

Precision Fused Silica Substrate
Variety of Sizes and Coating Options Available
Low Coefficient of Thermal Expansion

λ/10 First Surface Mirrors are ideal for demanding beam steering and reflection applications in the visible and IR spectra. With a precision fused silica substrate, the mirrors feature a low coefficient of thermal expansion while being highly durable and resistant to abrasion.

These precision mirrors can be utilized in a host of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
