The 66-090 50 mm Dia. SCHOTT OG570 Orange Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a specific wavelength. This filter, sourced from Edmund Optics, is a circular shape with a diameter of 50 mm and a thickness of 3 mm, making it suitable for a wide range of optical systems.
The filter is made from SCHOTT optical glass, a high-quality material known for its excellent optical properties. The OG570 designation indicates that this filter has a cut-on wavelength of 570 nm, meaning it begins to transmit light at this wavelength and above. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths below 570 nm. This makes it ideal for applications where orange light and longer wavelengths need to be isolated or emphasized.
The filter features a coating on both the front and back surfaces, identified as EDM 54-656. This coating is likely designed to enhance the filter's performance, such as by increasing transmission in the passband or reducing reflection. The filter's shape is described as a Thin Lens, suggesting it may have some light-bending properties, although this is not explicitly stated in the provided data.
