Fused silica and Zerodur offer the lowest thermal expansion (<0.1×10⁻⁶/K), ideal for stable environments. Borosilicate glass provides good balance of stability and cost for most industrial applications.
Substrate imperfections directly transfer to the reflective surface, causing wavefront errors, beam divergence, and reduced collimation accuracy. Surface flatness below λ/10 is critical for precision applications.
Yes, aluminum with nickel plating is common where weight or thermal conductivity matters, but requires careful thermal management due to higher expansion coefficients.
