Infrared with 1.1mm Thickness compensation Objective Lens 2mm Focal Length 100x Working Distance 12.16mm

PAL-100-NIR-LC11-A

main product photo
This is a high NA infinity corrected objective lens for laser processing (fundamental of YAG laser). Its glass-thickness- compensation optical design makes it possible to realize an ideal beam spot size and quality even if it was processed thorough a cover glass.
  • Two kinds objective lenses are available. They are designed to correct aberration depending on the thickness of cover glass. (t= 0.7 mm and 1.1 mm)
  • With its long working infinity correction function; this objective lens can be used for a laser system and coaxial observation.
  • It is also used for the observation of Near Infrared light.
  • High resolution type (NA=0.65) is also available.
  • This objective lens can be used with a pulse laser of visible light (532nm).
  • Laser Damage Threshold(reference): 0.1J/cm2 (532nm), 0.2J/cm2(1064nm) (Laser pulse width: 10ns, repetition frequency: 20Hz)
More Information
Name Infrared with 1.1mm Thickness compensation Objective Lens 2mm Focal Length 100x Working Distance 12.16mm
Weight 0.3500kgs
Standard Coatings Available No
Guide
  • Available fixed Objective Lens Holder（LHO-26).
  • When the objective lens is fixed to a 2-axis holder, please consult our Sales Division.
  • For laser processing, we offer an Observation Unit with Coaxial Illumination and a Dichroic Case for Laser Introduction .
  • If you need an objective lens that is compatible with a thin cover glass, please contact our Sales Division.
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.
  • When the thickness of cover glass is not same as the specified, designed specifications may not be achieved due to aberration. If the incident laser beam femtosecond is below 100fs, there is apossibility that the pulse width will spread.
  • If the incident laser beam femtosecond is below 100fs
  • 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.
