55mm Focal Length Partially Telecentric Video Lens

Product Family Description

• 2/3", C-Mount Lens
• Up to 1.3 MegaPixels, 7µm Pixel Size Sensors
• Function as Both Macro and Telecentric Lens
• ±12.5mm of Object Movement Before 1% Error Image Scale Occurs

55mm FL Partially-Telecentric Imaging Lenses allow ±12.5mm of object movement (at 0.5X magnification) before a 1% error in image scale occurs, while conventional lenses permit typically ±1.7mm of movement under the same conditions. Telecentric lenses yield constant magnification over a range of working distances, virtually eliminating viewing angle error. The lens’ protective window (at C-Mount end) needs to be removed for use with adapter lenses. 55mm FL Partially-Telecentric Imaging Lenses are ideal in machine vision applications requiring accurate measurement of three-dimensional objects with slight height variations. By eliminating the perspective distortion and magnification error inherent in conventional lenses, they yield dimensionally accurate images that are easily interpreted by software. 

For mounting these lenses, our Industrial Boom Stands and mounting adapters are recommended as workstation platforms. Ring light guides can not be mounted directly on this lens because of the front focusing adjustment.
