Infrared Objective Lens 2mm Focal Length 100x Working Distance 10mm

PAL-100-NIR-HR

main product photo
This is a high NA infinity corrected objective lens for laser processing (femtosecond laser and fundamental of 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.
◦PAL-20-NIR-LC00/PAL-20-NIR-HR-LC00/PAL-50-NIR-HR-LC00 include protective glass unit (t=1.8mm). The protective glass will help protect the objective lens from debris spattering and scattered by laser processing. The protective glass unit can be replaced.
◦These variety of objective lens can be used with a pulse laser of visible light such as 532nm. The damage threshold of each lens is 0.1J/cm2 at 532nm, 0.2J/cm2 at 1064nm (reference). (Laser pulse width 10nSec, repetition frequency 20Hz)

Guide
  • Available fixed objective lens holder (LHO-26).
  • WEB Reference Catalog Code/W4024
  • When the objective lens is fixed to a 2 axis holder, please consult our Sales Division.
  • For laser processing, we offer a dichroic block (DIMC WEB Reference Catalog Code/W2041) and for laser unit with coaxial illumination and observation (OUCI-2).
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.
  • 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 there may be 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.
  • PAL-20-NIR-HR-LC00/PAL-50-NIR-HR-LC00 is designed in consideration of the thickness of including protective glass. If user removes the protective glass, the objective will not meet the performance specifications noted.
