Learn more about the advantages of telecentricity, including parallax error elimination, telecentric lenses, depth of field, and distortion, at Edmund Optics.

Telecentric Lenses can grow quite large and heavy with small magnifications, as such magnifications require large front optics. Learn more at Edmund Optics.

Elimination of parallax and distortion play a large role in determining the quality of certain telecentric lenses. Learn more at Edmund Optics.

Object space and image space are the two types of telecentricity. These refer to the exit and entrance pupil locations of an optical system.

Fixed magnification lenses typically function properly at a single working distance and are specified by their magnification. Learn more at Edmund Optics.

Optical lens geometries control light in different ways. Learn about Snell's Law of Refraction, lens terminology and geometries at Edmund Optics.

Fixed focal length, zoom, and macro lenses are all variable magnification lenses. Learn more at Edmund Optics.
