Optical loupes
First Claim
1. Optical loupes, including:
- a support means for wearing on a user'"'"'s head, the support means having two eyepieces, so that when the loupes are worn by a user, the eyepieces are disposed in front of the user'"'"'s eyes, each eyepiece having;
(a) an objective having an objective axis;
(b) an ocular having an ocular axis, the ocular and the ocular axis being arranged at an obtuse angle with respect to the objective and the objective axis, the objective and the ocular being arranged in side by side relationship; and
(c) light transfer means for transferring light from the objective to the ocular.

Abstract
Optical loupes are disclosed which include eyepieces (21) having an ocular (40) and an objective (42). A transfer tube (44) is mounted for transferring light between the ocular (40) and objective (42). The objective (42) is arranged at an obtuse angle with respect to the ocular and the ocular and objective are in side by side relationship. The transfer tube includes a transfer means having mirrors for transferring light from the objective to the ocular. A light source (38) including a plurality of diodes (100) is mounted between the eyepieces (21) of illuminating a work area. The eyepieces (21) can be adjusted in the interpupliery direction by adjustment nobs (35) which engage in slots (34) on a support bar (22) which hold the eyepieces (21).

48. Optical loupes, including:
a frame for wearing on a user'"'"'s head, the frame supporting two eyepieces so that when the loupes are worn by a user, the eyepieces are disposed in front of a user'"'"'s eye, each eyepiece having;
an objective, and an ocular arranged at an angle with respect to the objective, so that when looking through the eyepieces a field of view is provided different to that which would be provided if looking only through the ocular;
a light source coupled to the frame for illuminating the field of view of the loupes, the light source including an array of light emitting diodes. - View Dependent Claims (49, 50, 51, 52, 53, 54)

55. Optical loupes, including;
-
a frame for wearing on a user'"'"'s head, the frame supporting two eyepieces so that when the loupes are worn by a user, the eyepieces are disposed in front of a user'"'"'s eye;
distance adjusting means for adjusting the distance between the eyepieces in the interpupillary direction, the distance adjusting means including;
(a) a slider coupled to at least one of the eyepieces;
(b) an adjustment knob coupled to the slider;
(c) a pinion gear fixed relative to the knob for rotation with the knob;
(d) a rack engaged with the pinion gear and fixed relative to the frame and, wherein when the knob is rotated the pinion is also rotated so that engagement between the pinion and rack causes movement of the knob, pinion and slider relative to the frame in the interpupillary direction so as to enable adjustment of said at least one eyepiece in the interpupillary direction. - View Dependent Claims (56, 57, 58, 59, 60)

61. An optical instrument including;
-
a first eyepiece and a second eyepiece through which a user of the instrument will look in order to observe an object;
the first and second eyepieces including an ocular each having an axis; and
the axes of the oculars being arranged such that the axes converge towards one another from a spacing of greatest dimension adjacent an end of the ocular through which a user looks to observe the object, towards an end of the ocular remote from the end adjacent the user, the amount of convergence being substantially the same as the convergence of the field of view of a user observing an object spaced from the observer by a distance of about 1 m. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69)
