Description
MidOpt LP171 Fused Silica Multi-Layer A/R Coated Protective Window
LP171 fused silica protective windows are made from an ultra-pure, synthetic optical material similar to fused quartz. They offer extremely low thermal expansion, high-resistance to shock, superior scratch resistance and excellent optical properties. They perform well in high-temperature applications, having the ability to withstand temperatures of up to 1100° C. They are also chemical resistant and have superior transmission in the UV through near infrared spectral ranges. LP171 includes a durable broadband multi-layer anti-reflection coating to limit reflection losses in the visible and near-infrared spectrums.
