◦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)

▶When the objective lens is fixed to a 2 axis holder, please consult our Sales Division.
▶For laser processing
Attention ▶When an objective lens is used in laser processing, use the diameter of the incident beam to extend to a size of half the pupil diameter (1/e2). A small light spot cannot be achieved when the incident beam is too narrow. Please note if there is a laser energy density increase, there will be a high possibility of damage to the objective lens.
▶The surface of an objective lens can be contaminated by debris during processing. To avoid this
