The C-Mount 0.1-0.9x f/5.5-3.0 Variable Macro Lens from Opto Engineering is a multi-configuration macro lens suitable for inspection of object sizes ranging from a few millimeters to some centimeters. Magnification and focus can be tuned by adjusting a lockable rotating knob. The lens magnification range can be selected by means of a set of extension tubes. This makes the lens ideal for prototyping purposes and machine vision applications requiring flexibility. Since the working f-number increases with the magnification, the optimum combination of field depth, image resolution, and brightness is maintained in any lens configuration. Moreover, the optical distortion approaches zero at any magnification, making this lens suitable for measurement applications.
Up to 2/3" C-Mount detectors
LTRN series LED illuminators with 28mm inner diameter (straight and oblique type)
LTLADC series continuous LED 75° low-angle direct ring lights
LTBFC series continuous flat side-emitting LED backlights
LTBRDC series continuous LED bar lights
Less than 0.07% distortion at any magnification makes this lens suitable for use in measurement applications
Changing the magnification also changes the lens workingf-number in such a way that resolution and distortion remain properly combined
