PAL-NIR (Infrared (NIR) Objective Lenses)
  • PAL-NIR (Infrared (NIR) Objective Lenses)
  • This is a high NA infinity correction objective lens for laser processing (femtosecond laser and fundamental of YAG laser).
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 splashes during processing. To avoid this, please have sufficient working distance (WD) and insert a thin protective glass on the objective.
▶If the incident laser beam femtosecond is below 100fs, there is a possibility that the pulse width will spread.
▶Magnification is the value when using the imaging lens f=200mm. When used in a microscope lens barrel from other manufacturers may have different magnifications. The actual magnification should be calculated from the ratio of the focal length of the objective lens and the focal length of theimaging lens to verify the focal length of the imaging lens barrel to be used.
▶PAL-20-NIR-HR-LC00/PAL-50-NIR-HR-LC00 is designed in consideration of the thickness of including protective glass. If using removed the protective glass, it does not meet the performance specifications.
