A long working distance objective with an infinite conjugated parfocal distance of 95mm
The color difference of visible spectral region is corrected, and the machining surface can be observed coaxial with the laser beam
Can be used for 355nm, 532nm laser processing
The corresponding cover glass thickness is t=0,t=0.7,t=1.1, which can be achieved by replacing the corresponding protective mirror base
