PAL/PAL-L (Long Working Distance Objective Lenses (90mm parfocal distance))
  • PAL/PAL-L (Long Working Distance Objective Lenses (90mm parfocal distance))
  • is the long working distance objective lens infinity correction function and par focal length 95mm, which can be used for a laser system and coaxial observation. To focus visible laser or microscopic observation of objects from a distance.
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.
▶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 the imaging lens to verify the focal length of the imaging lens barrel to be used.
