36-573 20 mm Dia. AR Coated Sapphire Protective Flat Window; t=2 mm NIR II 750-1550nm
This product is a 20 mm diameter Flat Window, offered by Edmund Optics, designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550 nanometers. The window is made from Sapphire (Al2O3), a highly durable and scratch-resistant material, making it an excellent choice for protective applications.
The window features Anti-Reflective (AR) coatings on both the front and back surfaces, following the EDM NIR-II Standard Curve. This coating significantly reduces surface reflections, thereby enhancing transmission and improving overall system performance. The coating is specifically designed for the NIR II spectrum, ensuring optimal performance within the specified wavelength range.
The window has a thickness of 2 mm, which provides a good balance between mechanical strength and optical performance. The thin lens shape of the window ensures minimal optical distortion, making it suitable for applications that require high-precision optical paths.
