    Abstract: A telecentric lens comprises a front optical group (20) defining a front optical axis (k), at least a first rear optical group (40), defining a rear optical axis (k'), and at least one lens aperture (30) positioned between the front optical group 20 and a respective rear optical group. Between the front optical group (20) and the lens aperture (30) are inserted at least two reflective or semi-reflective elements arranged in such a way that at least a part of the rays coming from the front optical group undergoes at least one double reflection before reaching the rear optical group (40).
