Product Family Description

High Transmission from 190 - 3500nm
High Chemical Resistance
Low Coefficient of Thermal Expansion

ISP Optics Quartz Windows feature crystalline quartz (SiO₂) substrates, providing high transmission from the UV to the MWIR. Unlike fused silica, crystalline quartz does not have hydroxide ion impurities, allowing for its use between 1.4 - 2.7µm with no dips in transmission. The material also has high chemical resistance, a low coefficient of thermal expansion, and relatively high hardness, making these windows advantageous for use in harsh environments or those with fluctuating temperatures. ISP Optics Quartz Windows are ideal for use in UV, visible, or infrared applications as protective windows to protect sensors, lasers, or other electro-optical components.
