The 14-522 is a 50 x 50 mm SCHOTT RG665 Red Colored Glass Longpass Filter, designed to transmit light with wavelengths longer than 665nm while blocking shorter wavelengths. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is made from SCHOTT RG665 glass, a material known for its excellent optical properties and durability. It has a thickness of 3mm, providing robustness and stability during operation. The rectangular base shape allows for easy integration into various optical systems.
The 14-522 filter features a cut-on wavelength of 665nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than 665nm. This makes it ideal for applications where longpass filtering is required.
The filter is coated on both the front and back with EDM 14-522, a coating that enhances its performance and durability. The shape of the filter is thin lens, further adding to its versatility in optical systems.
