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.
Optics & Optical Coatings
- With its long working distance and corrected field curvature, its natural observation image is obtained to the periphery of viewing the field.
- It is the long working infinity correction function that is used to introduce a laser system and coaxial observation.
- It allows observation of the sample with visible light (400 – 500nm).
- Laser Damage Threshold (Typical) 0.09 J/cm2 (266nm), 0.1J/cm2 (355nm), 0.2J/cm2 (532nm)
(Laser pulse width 10ns, repetition frequency 20Hz)
