◦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.

Guide | ▶Available fixed objective lens holder (LHO-26). WEB Reference Catalog Code/W4024 ▶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 |
