The 87-819 is a Bandpass Filter with a diameter of 12.5 mm and a thickness of 3.5 mm, sourced from the reputable vendor Edmund Optics. This filter is specifically designed for a central wavelength of 1400nm, with a cut-on wavelength of 1387.5nm and a cut-off wavelength of 1412.5nm.
The Bandpass Filter is a type of optical filter that allows only a narrow band of wavelengths to pass through while blocking other wavelengths. This particular model is hard coated, which enhances its durability and resistance to wear and tear. The filter's base shape is circular, and it is made from UVFS Mal-1965 material, as indicated by its Material ID.
The 87-819 filter features a Thin Lens shape and comes with identical coatings on both the front and back, specifically the EDM 87-819 coating. This coating is designed to optimize the filter's performance and ensure the highest quality results.
