Long Working Distance Objective Lens 10mm Focal Length 20x Working Distance 31.1mm

PAL-20-L-A

Skip to the beginning of the images gallery

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.

Details

◦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.

Nom	Long Working Distance Objective Lens 10mm Focal Length 20x Working Distance 31.1mm
Poids	0.2800kgs
Standard Coatings Available	Non
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, we offer a dichroic block (DIMC WEB Reference Catalog Code/W2041) and for laser unit with coaxial illumination and observation (OUCI-2).
Remark	-
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, please have sufficient working distance (WD) and insert a thin protective glass on the objective. Magnification is the value when using the imaging lens f=200mm. When used in a microscope lens barrel from other manufacturers there may be different magnifications. The actual magnification should be calculated from the ratio of the focal length of the objective lens and the focal length of the imaging lens to verify the focal length of the imaging lens barrel to be used.
