The 66-082 50 mm Dia. SCHOTT GG475 Yellow Longpass Color Glass Filter is a specialized optical component designed for applications requiring wavelength selectivity. This filter, sourced from Edmund Optics, is a circular element with a 50 mm diameter and a thickness of 3 mm.
The filter is made from SCHOTT GG475, a high-quality glass material known for its excellent optical properties. It is designed to transmit light with wavelengths longer than 475 nm, making it a yellow longpass filter. The cut-on wavelength is precisely set at 475 nm, ensuring reliable performance in its intended applications.
The filter's coating is another crucial aspect of its design. Both the front and back surfaces are coated with EDM 54-651, a coating that enhances the filter's performance and durability. This coating helps to ensure accurate wavelength transmission and provides protection against environmental factors that could degrade the filter's performance over time.
The filter's shape is described as a thin lens, indicating its suitability for use in a wide range of optical systems. The catalog number for this item is 66-082, and it is currently in stock, according to the vendor's website.
