Long Working Distance Objective Lenses (95mm parfocal distance) / PAL_PAL-L
The long working distance objective lens infinity correction function and par focal length 95mm can be used for a laser system and coaxial observation. The objective will allow user to focus a visible laser or microscopic observation of objects from a distance.
Chromatic aberration is corrected in the visible range (400 − 700nm).PAL/PAL-L has a long working distance and a corrected field curvature. Its natural observation image is obtained to the periphery of the visual field.
