Infrared (NIR) Objective Lens / PAL-10-NIR-A

This is a high NA infinity corrected objective lens for laser processing (YAG laser). You can also observe the laser beam coaxially with a laser processed surface that is designed to reduce the aberration of the visible wavelength.

  • With its long working distance and field curvature corrected, its natural observation image is obtained to the periphery of the visual field.
  • It is the long working infinity correction function that is used to introduce a laser system and coaxial observation.
  • It is also used for the observation of infrared light.

Guide
  • Available fixed objective lens holder (LHO-26).
  • When the objective lens is fixed to a 2 axis holder, please consult our Sales Division.
  • We offer a coaxial illumination-equipped observation unit (OUCI) and a dichroic case for laser introduction (DIMC) as components for laser processing optics.
Attention
  • When an objective lens is used in laser processing, use the diameter of the incident beam to extend to a size of half the pupil diameter (1/e2). A small light spot cannot be achieved when the incident beam is too narrow. Please note if there is a laser energy density increase, there will be a high possibility of damage to the objective lens.
  • The surface of an objective lens can be contaminated by debris during processing. To avoid this, please have sufficient working distance (WD) and insert a thin protective glass on the objective.
