49-642 20 mm Dia. UVFS Round Protective Flat Window; t=2 mm VIS-NIR 400-1000nm
The 49-642 is a 20 mm diameter, thin, flat window made from UVFS material, specifically UVFS Mal-1965. This window has a thickness of 2 mm and is designed for use in the visible to near-infrared spectrum, covering wavelengths from 400 to 1000 nm.
The window features a coating on both the front and back surfaces, specifically the EDM VIS-NIR 0SP 200-2000 coating. This coating is designed to provide high transmission across the specified wavelength range, making it ideal for applications that require clear visibility or signal transmission in the visible to near-infrared spectrum.
The window is shaped as a thin lens, which can provide some focusing or collimating properties, depending on the application. However, its primary function is to protect optical elements or systems from environmental contaminants or damage.
This window is available from Edmund Optics and is currently in stock, according to the vendor's website. For more information, including pricing and availability, please refer to the provided weblink.
