TEC-M55

Navitar also off ers the TEC-M55 telecentric C-mount
lens for 2/3” format cameras. This 55 mm F/2.8

telecentric lens

maintains constant perspective and

magnifi cation.

Conventional lenses are often unable to accurately

portray objects which are slightly out of focus or at

diff erent distances from the lens. Constant perspective

and magnifi cation are maintained with a telecentric

lens, so the size of the image will not change.
