optical properties    

The glass SIMAX is transparent and clear; it does not show substantial absorption in visible spectrum. Permeability of ultra-violet rays enables the products made of SIMAX glass to be used for photochemical reactions.

refractive index (λ = 587,6 nm) nd = 1.473

photoelastic constant (DIN 52314) K = 4,0.10-6 mm2.N-1
