Near Ultra-violet (NUV) Objective Lens
PAL-50-NUV-HR-L-B
This objective lens can be used for laser machining using pulsed laser of THG (355nm) YAG laser. 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.
◦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 ultra-violet light.
◦This objective lens can be used with a pulse laser of visible light (532nm).
◦Laser Damage Threshold (Typical) 0.05J/cm2 (355nm), 0.1J/cm2 (532nm) (Laser pulse width 10ns, repetition frequency 20Hz)
