The telecentric lens is very suitable for measuring the product size at high magnification with no expansion of the object within the depth of focus, less distortion of the surroundings.
Since it is a fixed magnification, there is no versatility like a zoom lens.
(There are many types of lens with a fixed magnification)
In addition, Since the magnification does not change, we only need to calibrate 1 time in order to measure.
■Telecentric Lens : WD110mm , magnification 2 times
■Lighting Since the lens is small and thin, the lighting is fixed separately.
