Lenses collect and focus light onto sensors, enabling image acquisition, detail recognition and optical measurement. Designs can be matched to CMOS and CCD sensor formats, pixel sizes and required resolution.
Industrial applications include photoelectric sensing, dimensional measurement and visual defect inspection. Compact imaging systems are also used in cameras, consumer devices, medical instruments and environmental monitoring.
Infrared, laser, spectral and distance-sensing systems benefit from an optical path designed for their wavelength, working distance and field of view. Focal length and aperture can be specified for close-up imaging, wide-angle coverage or long-range observation.
