The WBMA-40C04-10-550 is a high-quality optical window, offered by OptoSigma, designed with a flat profile and a circular shape. This window, with a diameter of 40 mm and a thickness of 4 mm, is fabricated from N-BK7, a popular glass type known for its excellent optical properties, including low autofluorescence and high transmittance in the visible spectrum.
This optical window features anti-reflection (AR) coatings on both the front and back surfaces, optimized for the 400-700 nm wavelength range. These coatings significantly reduce reflection losses, thereby enhancing the overall transmission of the window. The coating material is specified as "opt m," which is a common coating material used in the industry.
The window's shape is defined as "Thin Lens," which implies that its thickness is much smaller than its diameter, allowing it to be considered as a thin lens in most optical systems. This window is currently in stock and available for immediate purchase through the provided weblink.
