Description

MidOpt LP286-58 AR Coated Borofloat Protective Window Visible Longpass Filter

LP286 windows are made with high-impact, thermal-resistant Borofloat, transparent in the near-UV, visible, and near-infrared ranges. It has a very low coefficient of thermal expansion and high shock resistance, withstanding temperatures up to 450° C for extended periods of time. Borofloat® is resistant to staining and harsh chemicals such as acids or alkalis, making it the protective window of choice when an economical window is needed for use in a harsh, high-temperature environment. LP286 windows have a rugged multi-layer, broadband anti-reflection coating to limit reflection loss in the visible and near-infrared spectrums. These windows also have an oleophobic (anti-smudge) coating to resist oils and moisture build-up, allowing for much easier cleaning.
