45-809 12.5 mm Dia. UVFS Round Protective Flat Window; t=2 mm UV-AR 250-425nm
The 45-809 is a circular, flat window with a diameter of 12.5 mm and a thickness of 2 mm. This window is made from UVFS material, specifically UVFS Mal-1965, which is known for its excellent optical properties. The window is designed to protect optical systems from environmental factors while minimally affecting the light path.
The window features a UV-AR coating on both the front and back surfaces, with a standard curve provided by Edmund Optics (EDM UV STD CURVE). This coating is designed to attenuate ultraviolet light in the 250-425nm range, making it ideal for applications where UV light needs to be controlled or eliminated. The coating also helps to reduce surface reflections, improving the overall transmission of the window.
The 45-809 is a thin lens type of optical element, meaning it has a small thickness relative to its diameter. This design helps to minimize optical aberrations and distortions, ensuring the highest quality optical performance. The window is available from Edmund Optics and is currently in stock, according to their website.
