Ultra-violet Objective Lens / 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)

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
