Glass Thickness Compensation NIR Objective / PAL-NIR-LC
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 0.1J/cm2 (532nm), 0.2J/cm2 (1064nm) (Laser pulse width: 10ns, repetition frequency: 20Hz)
