1. A lens mount system for mounting optical elements in front of a lens having an optical axis, comprising:
- (a) a holder having a slide channel lying in a plane generally normal to the optical axis, said slide channel having opposite open ends;
(b) an optical element slidably insertable into the slide channel through one of the open ends thereof along an insertion direction; and
(c) adjustment means for variably positioning the optical element to a selected position in the slide channel, including a positioning wheel mounted for turning movement on the holder, said positioning wheel resiliently engaging and moving the optical element to the selected position during such turning.

Abstract
A positioning wheel resiliently engages and moves an optical element to a selected position within a channel of a holder mounted in front of a camera lens. A brake mechanism prevents the optical element from accidentally falling out of the channel. A handle-operated camming mechanism provides for a quick lock/unlock interlock of a rotary holder in a desired angular orientation.

11. A lens mount system for mounting optical elements in front of a lens having an optical axis, comprising:
-
(a) a holder having a slide channel lying in a plane generally normal to the optical axis, said channel having opposite open ends; (b) an optical element slidably insertable into the slide channel through one of the open ends thereof along an insertion direction; (c) a manually turnable positioning wheel mounted on the holder for turning movement about a turn axis, said wheel extending into the channel for engagement with the optical element to move the same during such turning movement; and (d) brake means on the holder for preventing the optical element from accidentally falling out of the channel past either open end thereof. - View Dependent Claims (12, 13, 14, 15)

16. A lens mount system for mounting optical elements in front of a lens having an optical axis, comprising:
-
(a) a pair of holders, each holding a respective optical element, one of the holders having an annular groove concentric with the optical axis and positioned within the other of the holders; and (b) quick lock/unlock camming means on the other holder for interlocking the holders together, including a handle operatively connected to, and moving, a cam into and out of camming engagement with the groove at any desired position around the groove.

17. A method of mounting optical elements in front of a lens having an optical axis, comprising the steps of:
-
(a) slidably inserting an optical element into an open end of a slide channel that lies in a plane generally normal to the optical axis; and (b) variably positioning the optical element to a selected position in the channel by turning a positioning wheel which resiliently engages and moves the optical element during such turning. - View Dependent Claims (18)
