Abstract

Abstract An optical bench comprising parallel, horizontal primary and secondary ways and a plate-like carrier seated on and slidable longitudinally along two of the ways. A secondary way is circular in cross section and is provided thereon with a longitudinally slidable collar having an external circumferential groove with side walls perpendicular to the ways. The carrier has a notch providing oppositely facing edges respectively receivable in diametrically opposed portions of the groove and engageable with the inner wall of the groove, such edges of the notch being vertical. With this construction, two of the ways fix the vertical position of the optic axis of an optical element on the carrier, while the notch edges in engagement with the inner wall of the groove in the collar fix the horizontal positions of the optic axis. The side walls of the groove maintain the carrier penpendicular to the ways. In practice, there are two of the circular ways in laterally spaced, parallel relation and each is equipped with at least one of the collars mentioned. One carrier on the optical bench will have its notch in engagement with a collar on one of the circular ways, while the next carrier on the bench will have its notch in engagement with a collar on the other circular way, the configuration of the carriers being such that each carrier clears the collar on the opposite circular way. With this construction, optical elements on the two carriers can be placed in very close proximity to each other.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 82 words
In an opticaL bench, the combination of: a. two parallel horizontal ways; b. an optical element carrier having a first edge seatable on and slidable longitudinally of one of said ways; c. a slide on and movable longitudinally of the other of said ways and having oppositely facing groove portions the side walls of which are perpendicular to said ways; and d. said carrier having oppositely facing edges respectively receivable in said groove portions and respectively engageable with the inner walls thereof.
Claim 2
Dependent Claim 82 words
In an opticaL bench, the combination of: a. two parallel horizontal ways; b. an optical element carrier having a first edge seatable on and slidable longitudinally of one of said ways; c. a slide on and movable longitudinally of the other of said ways and having oppositely facing groove portions the side walls of which are perpendicular to said ways; and d. said carrier having oppositely facing edges respectively receivable in said groove portions and respectively engageable with the inner walls thereof.
Claim 3
Dependent Claim 113 words
In an optical bench, the combination of: a. parallel, horizontal primary and secondary ways; b. an optical element carrier having a primary edge seatable on said primary way and slidable longitudinally of said primary way; c. said secondary way being circular in cross section; d. a collar slidable longitudinally of said secondary way and having therein an external circumferential groove with side walls perpendicular to said ways; e. said carrier having a notch providing oppositely facing edges respectively receivable in diametrically opposed portions of said groove and engageable with the inner wall of said groove; and f. said oppositely facing edges of said notch being perpendicular to said primary edge of said carrier.
Claim 4
Dependent Claim 113 words
In an optical bench, the combination of: a. parallel, horizontal primary and secondary ways; b. an optical element carrier having a primary edge seatable on said primary way and slidable longitudinally of said primary way; c. said secondary way being circular in cross section; d. a collar slidable longitudinally of said secondary way and having therein an external circumferential groove with side walls perpendicular to said ways; e. said carrier having a notch providing oppositely facing edges respectively receivable in diametrically opposed portions of said groove and engageable with the inner wall of said groove; and f. said oppositely facing edges of said notch being perpendicular to said primary edge of said carrier.
Claim 5
Dependent Claim 28 words
An optical bench as set forth in claim 2 wherein the inner end of said notch is seatable on the inner wall of said groove in said collar.
Claim 6
Dependent Claim 33 words
An optical bench according to claim 2 wherein there are two of said primary ways in parallel horizontal relation, said primary edge of said carrier being seatable on both of said primary ways.
Claim 7
Dependent Claim 58 words
An optical bench as defined in claim 4 wherein there are two of said secondary ways respectively disposed on opposite sides of and above said primary ways, each of said secondary ways having one of said collars thereon, said oppositely facing edges in said notch of said carrier being receivable in said groove in either of said collars.
Claim 8
Dependent Claim 65 words
An optical bench according to claim 5 wherein said carrier is provided with two of said primary edges on opposite sides thereof, and is provided with two of said notches on opposite sides thereof, either of said primary edges being seatable on said primary ways, and the oppositely facing edges of either of said notches being receivable in said groove in either of said collars.
Claim 9
Dependent Claim 25 words
An optical bench as set forth in claim 4 wherein said primary ways are rectangular in cross section with their longer cross sectional dimensions vertical.
Claim 10
Dependent Claim 29 words
An optical bench as defined in claim 2 wherein said carrier is a plate having an edge which defines said primary edge and in which said notch is formed.
Claim 11
Dependent Claim 88 words
A fixture for mounting an optical element on said carrier of claim 2, including: a. a turntable having a vertical axis of rotation; b. a primary boss on the upper surface of said turntable corresponding to said primary way and engageable by said primary edge of said carrier; and c. a secondary boss of circular cross section on the upper surface of said turntable and corresponding to said secondary way and having diametrically opposed portions respectively engageable by said oppositely facing edges of said notch in said carrier.
