Description
MidOpt LP286 Borofloat® Oleophobic A/R Coated Protective Window
LP286 windows are made with high-impact, thermal-resistant Borofloat®, which is 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. MidOpt LP286 windows have a rugged multi-layer, broadband anti-reflection coating to limit reflection loss in the visible and near-infrared spectrums. These windows are also available with an oleophobic (anti-smudge) coating to resist oils and moisture build-up, allowing for much easier cleaning.
