｜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. VGA compatible
｜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 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
Use a macro lens
Uses a telecentric lens
When using a macro lens, distortion can be seen due to parallax between the center and edges of the screen, even when shooting an object from directly above.
However, when using a telecentric lens, distortion due to parallax between the center and edges of the screen is extremely small, allowing accurate image information to be obtained regardless of where the object is displayed on the screen.
