89-756 36 mm Dia. Mounted NUV Machine Vision Imaging Filter; t=1.75 mm 325nm
The 89-756 is a 36 mm diameter, 1.75 mm thick bandpass filter developed by Edmund Optics for machine vision imaging applications. This filter is designed to transmit light in the near-ultraviolet (NUV) range, specifically centered around 325nm.
The filter's construction includes a UVFS MAL-1965 material ID, which is a common choice for NUV applications due to its high transmittance in this region. The filter's cut-on wavelength is 277.5nm, and the cut-off wavelength is 372.5nm, providing a relatively narrow bandwidth for precise imaging.
The 89-756 filter features a thin lens shape, which is beneficial for applications where minimal optical path deviation is required. The front and back surfaces of the filter are coated with EDM 89-753, a coating that enhances the filter's performance and durability.
