54-659 12.5 mm Dia. SCHOTT RG665 Red Longpass Color Glass Filter 665nm

The 54-659 12.5 mm Dia. SCHOTT RG665 Red 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 12.5 mm diameter and a thickness of 3 mm, making it suitable for a wide range of optical systems.

The filter is made from SCHOTT glass, a high-quality material known for its excellent optical properties. It is designed to cut on at 665nm, allowing light at this wavelength and longer to pass through while blocking shorter wavelengths. The cut off is 0, indicating that it allows all longer wavelengths to pass through.

The filter features a coating on both the front and back surfaces, identified as 'edm 54-659'. This coating is likely designed to enhance the filter's performance and durability. The filter's shape is described as a Thin Lens, suggesting that it may have some light-bending properties in addition to its filtering function.
