When changing the object distance within the telecentric range, the imaging scale remains almost constant. This is particularly important for lenses with low magnifications, as these have a large depth of field, which is why it is only possible to focus roughly on the object. Optical 3D metrology with telecentric lenses leads to the lowest measurement errors. Telecentric lenses with fixed magnification achieve the best imaging quality.
