Glass Thickness Compensation Ultra-violet Objective Lenses
PFL-UV-AG-LC
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.
Optics & Optical Coatings
- 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)
