Main features

A telecentric lens is a lens that has a constant magnification at any position within the object distance.
There is no change in magnification within the depth of field.
There is no image distortion due to the field of view, and the accuracy of shape measurement of deep parts is greatly improved.

Features of telecentric lenses

1.Can be used as a medium to high magnification macro lens.

→　 The price will be higher than the macro lens, but the performance will also be improved.

2.There is no expansion or contraction of the object within the depth of focus.

　→Measurement error can be reduced when measuring dimensions.

3.You can reduce the ambient distortion due to parallax.

4.You can choose the focal length.

(Short-distance type WD65mm and long-distance type WD110mm are available)

5.When used with coaxial lighting, uneven illuminance of the object can be reduced.
　

Non-coaxial type and coaxial lighting type are available

Example of use

Comparison between using a telecentric lens and using a macro lens

using a macro lens

using a telecentric lens

If you use a macro lens, the parallax between the center and the edge of the screen will be distorted even if you shoot the observation object from directly above.
However, when a telecentric lens is used, the distortion due to the parallax between the center and the edge of the screen is extremely small, accurate image information can be obtained no matter where the observation object is projected on the screen.
