Glass Thickness Compensation Ultra-violet Objective Lenses

◦Two kinds objective lenses are available. They are designed to correct aberration depending on the thickness of cover glass.(t= 0.7 mm and 1.1 mm)
◦It is the long working infinity correction function that is used to introduce a laser system and coaxial observation.
◦It is also used for the observation of ultra-violet light.
◦Laser Damage Threshold(reference): 0.09 J/cm² (266nm), 0.2J/cm² (532nm)　(Laser pulse width: 10ns, repetition frequency: 20Hz)
