Double telecentric lens for maximum image size 1/3″

The telecentric lens is the culmination of microscope optical technology cultivated over many years. The greatest feature is that there is no size variation within the depth of field where resolution is maintained. OPTART contributes to user needs by providing cutting-edge design lenses for FA cameras, which are becoming increasingly large and high-definition, as well as cost-conscious general-purpose lenses.

  • All models coaxial epi-illumination & straight type
  • Uniform illumination for the coaxial epi-illumination type
  • Deep depth of field with variable aperture
  • Achieves low optical distortion
  • C-mount
Telecentric lens required for FA and machine vision
