The 14-523 is a 50 x 50 mm SCHOTT RG695 Black Colored Glass Longpass Filter, designed to transmit light at wavelengths above 695nm while blocking shorter wavelengths. This filter is sourced from Edmund Optics and is available for purchase through their website, with a current status of being in stock.
This rectangular filter is made from a single piece of Schott glass, a material well-known for its excellent optical properties. The filter has a thickness of 1mm, making it suitable for a wide range of optical applications. The front and back surfaces of the filter are coated with the EDM 14-523 coating, which enhances its performance and durability.
The physical data of the filter indicates a cut-on wavelength of 695nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength, on the other hand, is 0nm, indicating that it blocks all wavelengths shorter than 695nm. This makes the 14-523 an ideal choice for applications where longpass filtering is required.
The filter is shaped as a thin lens, which can be beneficial in certain optical systems. The geometry of the filter is 50mm in width and 50mm in height, providing a large surface area for light to pass through.
