48-635 25.4 mm Dia. Hoya B-390 (UV-VIS) Blue-Violet Colored Glass Bandpass Filter 390nm

The 48-635 25.4 mm Dia. Hoya B-390 (UV-VIS) Blue-Violet Colored Glass Bandpass Filter 390nm is a high-quality optical component sourced from Edmund Optics. This filter is designed with a specific wavelength of 390nm, making it ideal for applications that require precise light filtration in the ultraviolet and visible spectrum.

The filter is made from a unique color glass material, identified as UVFS Mal-1965, which provides excellent optical performance. It features a circular shape with a diameter of 25.4mm and a thickness of 2.5mm, ensuring durability and stability in various optical systems.

The B-390 filter is coated on both the front and back with the EDM 48-631 coating. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission efficiency. The filter's geometry is shaped as a thin lens, further optimizing its light-filtering capabilities.

The filter's physical data includes a central wavelength (CWL) of 390nm, which is the wavelength at which the filter provides the highest transmission. This makes it ideal for applications that require precise light filtration at this specific wavelength.
