Infrared (NIR) Objective Lens / PAL-50-NIR-L
This is a high NA infinity corrected objective lens for laser processing (femtosecond laser and fundamental of YAG laser). You can also observe the laser beam coaxially with a laser processed surface that is designed to reduce the aberration of the visible wavelength.

◦With its long working distance and field curvature corrected, its natural observation image is obtained to the periphery of the visual field.
◦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 infrared light.
◦PAL-20-NIR-LC00/PAL-20-NIR-HR-LC00/PAL-50-NIR-HR-LC00 include protective glass unit (t=1.8mm). The protective glass will help protect the objective lens from debris spattering and scattered by laser processing. The protective glass unit can be replaced.
◦These variety of objective lens can be used with a pulse laser of visible light such as 532nm. The damage threshold of each lens is 0.1J/cm2 at 532nm, 0.2J/cm2 at 1064nm (reference). (Laser pulse width 10nSec, 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. ▶The surface of an objective lens can be contaminated by debris during processing. To avoid this, please have sufficient working distance (WD) and insert a thin protective glass on the objective. ▶If the incident laser beam femtosecond is below 100fs |
