Ultra-violet Objective Lenses / PFL-UV-AG
This objective lens can be used for laser machining using pulsed laser of SHG (532nm) YAG laser and FHG (266nm) YAG. Chromatic aberration is suppressed in both the visible and UV laser wavelength, achieving a high transmittance.
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 ultra-violet light.
Laser Damage Threshold (Typical) 0.09 J/cm2 (266nm), 0.2J/cm2 (532nm)
(Laser pulse width 10ns, repetition frequency 20Hz)
