68-489 12.5 mm Dia. UVFS Round Protective Flat Window; t=2 mm VIS 0 425-675nm
The 68-489 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 provide protection while allowing the transmission of light within the visible spectrum, specifically from 425 to 675 nm.
The window features a standard coating on both the front and back surfaces, specifically the EDM Vis-0 std curve coating. This coating is designed to enhance the window's performance in the visible spectrum, providing a high level of transmittance and durability. The coating also helps to reduce reflections, improving the overall efficiency and clarity of the window.
The 68-489 is sourced from Edmund Optics, a leading vendor in the field of optical components. According to the vendor, the window is currently in stock, indicating its availability for immediate use. The window's geometry is that of a thin lens, making it suitable for a wide range of applications where a flat, protective window is required.
