The 14-537 is a 50 x 50 mm SCHOTT RG830 Black Colored Glass Longpass Filter, designed with a cut-on wavelength of 830nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their official website.
The filter is made of color glass, a type of optical filter that uses dyes or pigments to absorb unwanted wavelengths. This specific model, the RG830, is designed to transmit wavelengths above 830nm while blocking those below. This makes it ideal for applications that require the isolation of specific wavelength ranges.
The filter has a rectangular base shape, with a thickness of 3mm, providing durability and stability. It features a thin lens shape, which is beneficial for applications that require a compact, lightweight optical component.
The physical data of the filter indicates that it has a cut-off wavelength of 0nm, meaning it blocks all wavelengths below 830nm. The coating on both the front and back surfaces of the filter is 'edm 14-537', which could be a specific coating applied by the manufacturer for enhanced performance or protection.
