Long Working Distance Objective Lens
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).
◦Two types of parfocal distance are available, 45mm and 90mm.
◦This parfocal 95mm lens has a long working distance and a corrected field curvature. Its natural observation image is obtained to the periphery of the visual field.
◦ 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.
Guide
▶Available fixed objective lens holder (LHO-20.32).
▶When the objective lens is fixed to a 2 axis holder, please consult our Sales Division.
▶For laser processing, we offer a dichroic block (DIMC-532R) and for laser unit with coaxial illumination and observation (OUCI).
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
