◦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)
