Strongly effecting the image quality

Opto Engineering TC 12K - Telecentric Lenses for 12K and 16K Line Scan Cameras

Advantages of telecentric lenses

With standard lenses an object appears to be smaller or bigger when it is closer or farther away from the lens. Unlike common optics, telecentric lenses only accept incoming ray bundles that are parallel to the optical axis; therefore the object size remains unchanged. This is essential when you must measure objects that cannot be precisely positioned (e.g. on a conveyor belt).

Moreover, telecentric lenses eliminate any perspective error and are therefore perfect when thick objects must be measured.

Telecentric lenses also outperform standard lenses when it comes to distortion: An image is distorted when straight lines in the object space appear as curved lines in the image space. Distortion is measured as a percent deviation. Opto Engineering telecentric lenses feature incredibly low distortion, typically under 0.05 % and deliver extremely accurate geometrical information.

Characteristics of the Opto Engineering TC 12K lenses

The Opto Engineering TC 12K telecentric lenses are designed to fit very large format line scan cameras. The 62.5mm image circle diameter combined with high resolution capabilities makes these lenses the ideal choice for 12KP and 16KP pixel line cameras.
