Bi-Telecentric Lens
In a bi-telecentric lens the chief rays of both the object and the image space are parallel.
This results in constant magnification independant of the object or image distance.

Non-Telecentric Lens
In a non-telecentric lens the chief rays of both the object and the image space are not parallel.
In this case magnification depends on both the object and image distance.
