LBTEK offers fixed focal length lenses characterized by compact size, high resolution, and low distortion (optical distortion <1%). Available in four focal lengths: 16 mm, 25 mm, 35 mm, and 50 mm, these lenses feature manually adjustable aperture and focus, with working distances ranging from 25 mm to infinity. Compatible with sensors up to 2/3" in size and equipped with C-mount optical interfaces, they easily integrate with cameras to deliver excellent imaging quality. Widely used in machine vision and industrial automation applications such as product defect inspection, flaw detection, and dimensional measurement.
Among LBTEK's fixed focal length lenses, the M5028-MPW3 model stands out with zero optical distortion and superior imaging performance. The series includes 16 mm, 25 mm, 35 mm, and 50 mm options, featuring manually adjustable apertures (F2.8–F16). While supporting sensors up to 2/3", note that the field of view decreases when used with smaller sensors (refer to provided FoV tables for specific sensor sizes). With standard C-mount interfaces, these lenses are fully compatible with LBTEK cameras like the acA2440-20gm and acA2440-20gc for seamless system integration.
