Fused silica quartz glass window
Fused silica window, with low thermal expansion, providing stability and resistance to thermal shock over large temperature excursions, wide thermal operating range and high laser damage threshold, is a better choice for transmission from UV to IR.
The wavelength of SYCCO general windows substrate(without coating)

Material: UV grade fused silica (China JGS1)
Bevel: <0.25mm X 45°
Coating: Optional (Uncoated, AR, HR, PR, Coating, etc.)
