Abstract
Abstract A binocular-viewing device suitable for use by opthalmologists containing binocular-viewing means with a double mirror reflector system and a lamp housing for illuminating an object, the lamp housing having a curved reflector and a lens system constituted by a single element having an aspherical face. So that the illuminating efficiency is high, the size and weight of the lamp and lamp housing is small and consequently the size and weight of the headpiece is small and can be carried on a spectacle frame.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
A binocular-viewing device having a headpiece, a headpiece housing containing binocular-viewing means including a pair of spaced apertures arranged at a spacing to accommodate the pupillary distance between a user''s eyes, means mounting said housing on said headpiece a lamp housing carried by and extending upwardly from the headpiece housing, a lamp positioned within the lamp housing with its central axis extending vertically, a curved reflector at the rear of the lamp, a lens system at the front of the lamp, the lens system being constituted by a single element having an aspheric face, the curved reflector and the lens system having a common axis, pivot means, said pivot means connecting the lamp housing to the headpiece housing whereby the direction of light transmitted by the lamp housing is varied when the lamp housing is tilted, a support ring secured to the lamp and engaging in the lamp housing, the relative location of the support ring and the lamp filament being at a distance from one another such that said axes intersect and the lamp filament is substantially on the central axis of the reflector and lens system.
Claim 2
Dependent Claim
188 words
A binocular-viewing device having a headpiece, a headpiece housing containing binocular-viewing means including a pair of spaced apertures arranged at a spacing to accommodate the pupillary distance between a user''s eyes, means mounting said housing on said headpiece a lamp housing carried by and extending upwardly from the headpiece housing, a lamp positioned within the lamp housing with its central axis extending vertically, a curved reflector at the rear of the lamp, a lens system at the front of the lamp, the lens system being constituted by a single element having an aspheric face, the curved reflector and the lens system having a common axis, pivot means, said pivot means connecting the lamp housing to the headpiece housing whereby the direction of light transmitted by the lamp housing is varied when the lamp housing is tilted, a support ring secured to the lamp and engaging in the lamp housing, the relative location of the support ring and the lamp filament being at a distance from one another such that said axes intersect and the lamp filament is substantially on the central axis of the reflector and lens system.
Claim 3
Dependent Claim
44 words
A binocular-viewing device according to claim 1 further comprising a retaining member engageable within the lamp housing and against the support ring, and a spring wire clip hinged to the housing and resiliently engaging the retaining member thereby retaining it in the lamp housing.
Claim 4
Dependent Claim
22 words
A binocular-viewing device according to claim 1 further comprising an infrared filter in the lamp housing positioned in front of the lens.
Claim 5
Dependent Claim
41 words
A binocular-viewing device according to claim 1 and further comprising means securing the headpiece housing tO the lenses of a pair of spectacles, the spectacles having a rigid frame, said spaced apertures being adjacent the outer faces of the spectacle lenses.
Claim 6
Dependent Claim
57 words
A binocular-viewing device according to claim 4 wherein the headpiece further comprises two pairs of spaced substantially parallel mirrors, the mirrors of each pair being substantially at right angles to those of the other pair and arranged to reflect diverging light entering the headpiece outwardly through the apertures to thereby provide stereopsis when viewed through the apertures.
Claim 7
Dependent Claim
43 words
A binocular-viewing device according to claim 5 further comprising resilient mounting means retaining the outer mirror of each pair within the headpiece housing and screw-threaded adjustment means cooperable with the mirror to vary the mirror position by resilient deformation of the mounting means.
Claim 8
Dependent Claim
34 words
A binocular-viewing device according to claim 6 further comprising a backing plate on the mirror, said screw-threaded adjustment means comprising a plurality of screws threadably engaging the headpiece housing and abutting the backing plate.
