Telecentric lenses Due to their telecentric perspective, the image scale does not change when changing the distance to the object (working distance) with telecentric lenses. Overview - telecentric lenses and corresponding accessories   Level up Print view    Product line - Magnifying telecentric lenses Features Image scale from 0.7 to 10 Object field from 0.4 x 0.3 mm and 9.4 x 7.1 mm Maximum image sensor diagonal / line 1.34" (= 21.4 mm) Large working distances with large image scales (magnification) Applications Measuring and inspection of very small, flat parts Inspection of very fine grid structures Especially precise when combined with telecentric lighting    Product line - Telecentric measurement lenses Features Image scale from 0.07 to 0.7 Object field from 6.6 x 4.9 mm and 100 x 75 mm Maximum image sensor diagonal / line 1.34" (= 21.4 mm) Lenses with large and small working distances at the same image scale Applications Measuring and inspection of parts Inspection tasks involving parts with optically difficult surfaces or material properties (very shiny, optically active materials, variable edge shapes) Inspection of parts located at different positions relative to the camera Completeness inspection of deeper parts with drillings, openings, recesses, etc. Especially precise when combined with telecentric lighting    Product line - Telecentric widefield lenses Features Image scale from 0.03 to 0.08 Object field from 77 x 58 mm and 360 x 230 mm Maximum image sensor diagonal / line 1" (= 16 mm) Low weight (front elements are Fresnel lenses) with very large object field Applications Inspection and completeness inspection of large, deep parts, such as catalytic converter elements, heat exchangers, etc. Most effective when in combination with monochromatic lighting
