Product description
Fused Silica material Advantages
1. Good UV and IR transmission;
2. Low thermal expansion, providing stability and resistance to thermal shock over large temperature excursions;
3. Wider thermal operating range;
4. High laser damage threshold Fused silica could be used for Fused Silica windows, Fused Silica lenses, prisms and
mirror substrates.
Note for Fused Silica Window:
(1). Custom-made Fused Silica windows at any size from Φ2.0mm to Φ350mm clear aperture are available.
Besides round, Fused Silica windows at shape of quadrate, triangular, or other polygonal are available
(2). Thickness from 1.0mm to 50.0 mm is available upon request.
(3). 100% clear aperture is available upon request.
(4). Better bevel is available upon request.
(5). Windows with Anti-Reflective(AR), High-Reflective(HR), Partial-Reflective(PR) coating are available.
