LWD Objective (45mm PFL) / EPL_EPLE
With its long working infinity correction function; this objective lens 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).It is possible to improve the response speed in the driving mechanism of the 45mm parfocal objective lens (SFS-OBL/ SFAI-OBL); with a lightweight auto focusing solution.
