OVERVIEW
The right material for the application
Taking full advantage of a complete inventory of materials, we supply optical materials across a wide range of grades and geometries — from premium low-expansion glasses to general-purpose optical glass.
Our material expertise lets us recommend the optimal substrate for your tolerance, environmental, and budget requirements. Where premium materials aren't required, we offer a wide selection of alternatives with equivalent performance at a lower-cost option.
SUBSTRATE MATERIALS
Available optical substrates
We maintain inventory across premium and general-purpose optical materials, supporting everything from precision components to large-size blanks.
Corning 7980
UV-grade fused silica with excellent transmission and homogeneity.
Schott Zerodur
Glass-ceramic with near-zero coefficient of thermal expansion.
Quartz
High-purity quartz for UV transmission and thermal stability.
Borofloat
Borosilicate float glass — durable, general-purpose optical glass.
BK7
Workhorse optical glass for visible and near-IR applications.
Sapphire
Exceptional hardness, broad spectral range, and chemical durability.
SiC
Silicon carbide with high stiffness and thermal conductivity.
ALON
Transparent aluminum oxynitride — armor-grade optical ceramic.
