3-Wavelengths Objective Lenses
PFL-UV/NUV-AG
This objective lens can be used for laser machining using pulsed laser of SHG (532nm), THG (355nm), and FHG (266nm) YAG laser. Objective lense provides high transmittance at three harmonic wavelengths of YAG.
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)
