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.
