MidOpt LP286-55 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.
