Large Format Lenses

50 mm Raptar Lens

Navitar's 50 mm Raptar lens is the perfect solution to machine vision applications that require a large sensor and lens combination. The 50 mm Raptar is an alternative to the traditional SLR camera lenses which are not manufactured to withstand environments traditionally found in industrial applications.

Our 50 mm lens exceeds industry requirements for MTF, relative illumination, and low distortion - all important characteristics when working with high cost, large format cameras.

Ideal for use with full frame 11 and 16 mega pixel sensors
Manual iris and focus control
Robust mechanical design
Positive, single point, focus and iris locks
Standard F-bayonet with option of a M42 or C-mount
Covers 43 mm diagonal sensor
