    製品の特長

    A telecentric lens is a lens that maintains a constant magnification at any position within the object distance range.
    There is no variation in magnification within the depth of field.
    It eliminates image distortion caused by the field of view and significantly improves the accuracy of shape measurements for parts with depth.

    Features of Telecentric Lenses

    1. It can be used as a medium- to high-magnification macro lens.
       →The price is higher than that of a standard macro lens, but the performance is also superior.
    2. There is no expansion or contraction of the object within the depth of focus.
       →Measurement errors can be minimized when measuring dimensions.
    3. Peripheral distortion caused by parallax can be reduced.
    4. You can select the working distance.
       →Available in short-range (W.D. 65 mm) and long-range (W.D. 110 mm) types.
    5. When used with coaxial lighting, unevenness in the illuminance of the target object can be reduced.
       →Available in non-coaxial and coaxial lighting types.

    <Usage Example>

    Comparison between using a telecentric lens and a macro lens

    Using a macro lens
    Using a telecentric lens.

    When using a macro lens, parallax distortion appears between the center and the edges of the image, even when shooting the subject from directly above.
    However, when using a telecentric lens, distortion caused by parallax between the center and edges of the image is extremely minimal, allowing for accurate image information regardless of where the object appears on the screen.
