1. An actuator system for use in an optical system of an endoscope, the actuator system comprising:
at least one actuator; and
a holder for receiving at least one optical element of the optical system, the holder is configured to be flat and extends in a holder plane, the holder comprising:
an outer enclosure;
a leaf spring; and
an inner platform;
wherein the outer enclosure at least partially surrounds the leaf spring and the leaf spring at least partially surrounds the inner platform,
the outer enclosure is elastically coupled to the inner platform via the leaf spring,
the inner platform is configured to receive the optical element,
the at least one actuator interacts with the inner platform; and
the holder is formed from one of a cold-rolled stainless steel sheet, an amorphous metal, or a nickel-titanium alloy.
