50X, 2nd and 3rd YAG Harmonic Objective Lens, 0.70mm Glass-Thickness Compensation

PFL-50-UV-AG-LC07-A

PFL-UV-AG-LC series are objective lenses of which magnification cover 20X,50X and 80X. They can be used in a laser processing machines which is using 266nm and 532nm YAG pulse 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. These objective lenses will well match with a laser repair processing for LCD or OLED module.
◦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)
◦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 ultra-violet light.
◦Laser Damage Threshold(reference): 0.09 J/cm2 (266nm), 0.2J/cm2 (532nm) (Laser pulse width: 10ns, repetition frequency: 20Hz)

Remark -
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.
  • 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.
