Claim:
1. An optical element holder for an optical instrument, the optical element holder comprising: a body comprising an optical input side, an optical output side, a thickness along a longitudinal axis between the optical input side and the optical output side, and a plurality of receptacles configured to retain respective optical elements and generally arranged in a transverse plane orthogonal to the longitudinal axis, wherein each receptacle is open to the optical input side and to the optical output side to define an optical path through the body parallel to the longitudinal axis; and a plurality of pusher components extending from the body, each pusher component comprising a spring member and at least one contact element extending from or separate from the spring member and having a contact surface positioned to be biased by the spring member toward at least one of the receptacles and into contact with an optical element retained in the receptacle, a contact element extending from or separate from the spring member, and the contact element comprises the contact surface, wherein each pusher component is configured to apply a biasing force against at least one optical element retained in a respective one of the receptacles to retain the at least one optical element in an aligned position at which the at least one optical element is parallel to the transverse plane.
