14-521 50 x 50 mm SCHOTT RG665 Red Colored Glass Longpass Filter 665nm
The 14-521 50 x 50 mm SCHOTT RG665 Red Colored Glass Longpass Filter is a specialized optical component designed for applications that require longpass filtering at a cut-on wavelength of 665nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
This filter is a Color Glass type, specifically designed for rectangular geometries. It boasts a width and height of 50mm each, with a thickness of 2mm, making it a substantial and robust optical element. The filter is made from SCHOTT RG665 glass, a material known for its excellent optical properties and durability.
The physical data of the filter indicates a cut-on wavelength of 665nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths longer than 665nm. This makes it ideal for applications that require the removal of shorter wavelengths, such as infrared spectroscopy or astronomy.
The filter features a coating on both the front and back surfaces, identified as 'edm 14-521'. This coating is likely designed to enhance the filter's performance, such as by increasing its transmission efficiency or durability. The filter's shape is described as a Thin Lens, suggesting it may have some light-focusing properties.
