The three-, six- or seven-glass-element lenses are mounted in compact metal housings, color-corrected for wavelengths from 400 to 1000 nm, and have focal lengths from 10 to 45 mm and speeds from f/1.5 to f/8. They have fixed- or variable-iris diaphragms with manual-lock or click-stop adjustment. Accessory extension tubes are available for magnification adjustment. Applications include controlling product manufacturing and assembly, and inspection for research, traffic surveillance and security.
