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.

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

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

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

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

Do you want to understand how a lens works? To do so, you must learn key terms for how the lens functions, including resolution. Find out more at Edmund Optics.

Distortion is an individual aberration that misplaces information but can be calculated or mapped out of an image. Learn more about distortion at Edmund Optics.
