Long Working Distance Objective Lenses

EPL/EPLE

With its long working infinity correction function; this objective lens can be used for a laser system and
coaxial observation.
The objective will allow user to focus a visible laser or microscopic observation of objects from a distance.

  • Chromatic aberration is corrected in the visible range (400 − 700nm).
  • Two types of parfocal distance are available, 45mm and 90mm.
  • This parfocal 95mm lens has a long working distance and a corrected field curvature. Its natural observation image is obtained to the periphery of the visual field.
  • It is possible to improve the response speed in the driving mechanism of the 45mm parfocal objective lens (SFS-OBL/SFAI-OBL); with a lightweight auto focusing solution.
