Claim 9

The telemicroscope of claim 1 wherein the barrel is formed of at least two portions coupled by screw threads, the two portions being adapted to be rotated relative to each other for focusing of the telemicroscope.

Claim 10

The telemicroscope of claim 1 comprising a plurality of the baffles.

Claim 11

A telemicroscopic apparatus comprising a telemicroscope mounted to a carrier for positioning in front of a person's eye, the telemicroscope having a tubular barrel with a front lens and rear lens fitting within the circumference of the barrel and a light absorbing annular baffle fitting within the circumference of the barrel and being positioned between the front lens and the rear lens, the baffle having an outer diameter substantially equal to the inner diameter of the tubular barrel, and having an inner surface which tapers to an inner edge.

Claim 12

A telemicroscopic apparatus comprising a telemicroscope mounted to a carrier for positioning in front of a person's eye, the telemicroscope having a tubular barrel with a front lens and rear lens fitting within the circumference of the barrel and a light absorbing annular baffle fitting within the circumference of the barrel and being positioned between the front lens and the rear lens, the baffle having an outer diameter substantially equal to the inner diameter of the tubular barrel, and having an inner surface which tapers to an inner edge.

Claim 13

The telemicroscopic apparatus of claim 10 wherein the carrier comprises a transparent plate.

Claim 14

The telemicroscopic apparatus of claim 11 wherein the transparent plate is a spectacle lens.

Claim 15

The telemicroscopic apparatus of claim 10 wherein the surfaces of the baffle are given a dull finish to enhance the light absorbing properties of the baffle.

Claim 16

The telemicroscopic apparatus of claim 10 wherein the baffle is sharpened to a knife edge along its smallest inner diameter.

Claim 17

The telemicroscopic apparatus of claim 10 wherein the outer diameter of the baffle is less than about 16.0 mm.

Claim 18

The telemicroscopic apparatus of claim 10 wherein the inner diameter of the baffle is greater than about 1.0 mm.

Claim 19

The telemicroscopic apparatus of claim 10 wherein the difference between the inner diameter and the outer diameter of the baffle is greater than 1.0 mm.

Claim 20

The telemicroscopic apparatus of claim 10 wherein the baffle is positioned next to a lens and prevents light from passing through a portion of a lens surface.

Claim 21

The telemicroscopic apparatus of claim 10 wherein the largest inner diameter of the baffle is substantially equal to the outer diameter of the baffle.

Claim 22

A telemicroscope comprising: a tubular barrel; a front lens and a rear lens fitting within the circumference of the barrel; a plurality of light absorbing annular baffles fitting within the circumference of the barrel and being positioned between the front lens and the rear lens, each baffle having an outer diameter substantially equal to the inner diameter of the barrel and having an inner surface which tapers to an inner edge sharpened to a knife edge, the surfaces of each baffle having a dull finish to enhance the light absorbing properties of the baffle; and a carrier to which the telemicroscope is mounted for positioning the telemicroscope in front of a person's eye, the telemicroscope being mounted such that the person is able to view and perceive a principal image of an object and a clear magnified image of the object simultaneously, the telemicroscope being mounted to the carrier at an angle such that the telemicroscope's central axis is angled relative to the proper central line of sight through the carrier, the end of the telemicroscope closest to the eye being displaced further from the central line of sight.

Claim 23

A telemicroscope comprising: a tubular barrel; a front lens and a rear lens fitting within the circumference of the barrel; a plurality of light absorbing annular baffles fitting within the circumference of the barrel and being positioned between the front lens and the rear lens, each baffle having an outer diameter substantially equal to the inner diameter of the barrel and having an inner surface which tapers to an inner edge sharpened to a knife edge, the surfaces of each baffle having a dull finish to enhance the light absorbing properties of the baffle; and a carrier to which the telemicroscope is mounted for positioning the telemicroscope in front of a person's eye, the telemicroscope being mounted such that the person is able to view and perceive a principal image of an object and a clear magnified image of the object simultaneously, the telemicroscope being mounted to the carrier at an angle such that the telemicroscope's central axis is angled relative to the proper central line of sight through the carrier, the end of the telemicroscope closest to the eye being displaced further from the central line of sight.
