Abstract
A micro-optical lens holder having a lens receiver movable within a collar. The lens receiver has an indentation therein in which the lens is placed and a longitudinally extending passageway for allowing light to pass through the lens. The collar circumscribes the lens receiver in such a manner that when the lens receiver is positioned within the collar, the collar exerts a force on the lens receiver to securely maintain the lens within the lens receiver. Lens replacement only requires the extraction of the lens receiver from the collar in order to replace the lens within the lens receiver with a lens of a different size.
Claims8
A lens holder comprising:
- (a) an elongated member, said elongated member having
- an indentation in one end thereof for removably receiving a lens therein.
- a longitudinally extending passageway therethrough interconnected at one end thereof with said indentation, said passageway being in optical alignment with said lens located within said indentation,
- a plurality of longitudinally extending, circumferentially spaced apart slots adjacent said indentation, and
- a threaded exterior portion adjacent the other end thereof;
- and
- (b) means circumscribing said elongated member for maintaining said lens within said indentation, said lens maintaining means having a tapered interior opening therethrough, with one end thereof engaaging said elongated member adjacent said slots, and
- said lens maintaining means having a threaded interior portion for matingly engaging said threaded exterior portion of said elongated member;
- whereby said lens may be easily replaced within said lens holder with a different lens.
A lens holder comprising:
- a substantially cylindrically shaped body portion having a taper at one end thereof and being of a preselected external diameter and having a threaded portion at the other end thereof of a preselected external diameter less than said preselected external diameter of said tapered portion, a longitudinally extending passageway formed through the entire length of said body, an indentation situated at one end of said passageway within said tapered portion of said body for receiving a lens therein, and a plurality of longitudinally extending, circumferentially spaced apart slots situated within said tapered portion of said body to allow deflection of said tapered portion of said body to take place about said indentation;
- and
- a collar, said collar being of substantially cylindrical configuration and having an internal passageway therein, said internal passageway having a tapered preselected internal diameter at one end thereof and a preselected internal diameter at the other end thereof as well as having internal threads therein;
- whereby said body containing a lens therein can threadably engage with said collar and wherein said tapered internal passageway of said collar exerts a pressure on said tapered portion of said body in order to secure said lens within said indentation of said body.
