The 14-551 is a rectangular filter from Edmund Optics, designed for use in optical systems requiring heat absorption and shortpass filtering capabilities. Measuring 50 x 50 mm with a thickness of 2 mm, this filter is made from SCHOTT KG3 colored glass, a material known for its excellent optical properties.
The filter's primary function is to cut on at 300 nm and cut off at 2700 nm, making it suitable for applications where short wavelengths need to be blocked while allowing longer wavelengths to pass through. This characteristic is particularly useful in fields such as astronomy, spectroscopy, and imaging, where precise wavelength control is essential.
The 14-551 filter features a Thin Lens shape, which is beneficial in systems where space is limited or where a flat surface is not required. The front and back of the filter are coated with "edm 14-551", a coating that likely enhances the filter's performance and durability.
