Dynasil 4000 Fused Silica/Silicon Dioxide (SiO2)
Dynasil 4000 Fused Silica, aka Silicon Dioxide (SiO2), is the perfect material for optical uses due to its above-average UV/IR transmission and low thermal expansion. It's mainly known for its high stability and resistance to thermal shock over large temperature excursions, its wide temperature operating range, and high laser damage threshold. Accumet provides a variety of expert lapping, polishing, and laser cutting services and stocks Dynasil 4000 Fused Silica / Silicon Dioxide for fast delivery.
