LED and laser bandpass filters

Delta Optical Thin Film has launched several LED and laser bandpass filters. They are optimised for specific LED and laser wavelengths and combine large angular tolerance with high transmission and provide at least OD4 out-of-band rejection in a large wavelength range. This makes these filters well suited for machine vision applications with near-infrared LED illumination or Nd:YAG laser based lidar applications.
