The 14-538 is a 50 x 50 mm SCHOTT RG850 Black Colored Glass Longpass Filter, specifically designed for use in optical systems that require longpass filtering at 850nm. 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 RG850 glass, a material known for its excellent optical properties and durability. It has a rectangular base shape and a thickness of 1mm, making it suitable for a wide range of optical applications. The filter is coated on both the front and back with EDM 14-538, a coating that enhances its longpass filtering capabilities.
The physical data of the filter includes a cut-on wavelength of 850nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths of light below 850nm. This makes it ideal for applications that require the removal of specific wavelengths of light.
The filter has a shape described as a Thin Lens, suggesting that it has been designed to minimize optical aberrations and distortions. This is particularly important in applications that require high precision and accuracy.
