Right-angle lenses save space
Available in two versions, the 90° Vario Focus Inspection Lenses provide a right-angle structure that allows easy viewing of interior walls and recesses in cramped areas. They can be used in a macro mode to infinity via a focusing stick in working distances from 2 mm (0.66X) to 3000 mm (), provide images that are unseen by the human eye and free of vignetting, and produce diffraction-limited image quality across the entire field of view. Designed for 1/2-in. format (8.1-mm image diameter) with a 50° angle of view, the lenses` iris can be adjusted from f/6 to f/16 and locked into position.
