Abstract
Abstract Lens supporting structure for a dual power microscope including a support pillar, a relay carrier and a slide. The support pillar includes a recess in which the relay carrier, of tubular configuration, is received. Within the relay carrier is a relay lens mounting cell. The slide, also of tubular configuration, is designed to support an eyepiece lens system at one of its ends, an objective lens system at its opposite end and is provided with a longitudinal slot intermediate its ends. When the tubular slide is assembled within the relay carrier the relay lens mounting cell is received within the longitudinal slot. With this arrangement, the opposite ends of the slot cooperate with the relay lens mounting cell to define the limits of relative movement between the tubular slide and the relay carrier. O-rings are provided between the tubular slide and the relay carrier and also between the relay carrier and the recess which receives the relay carrier to center the tubes with respect to each other and with respect to the recess which receives the relay carrier. Apparatus is also provided to permit relative movement between the relay carrier and the support pillar.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
Apparatus for supporting the optical elements of a microscope, said apparatus comprising: a. support means, said support means including carrier receiving means; b. carrier means in the general form of a hollow tubular member at least partially disposed within said carrier receiving means, said carrier means including relay lens mounting means; and c. slide means in the general form of a hollow tubular member, said slide means including objective lens supporting means and eyepiece lens supporting means, said slide means further including an elongated through aperture located between said objective lens supporting means and said eyepiece lens supporting means, said slide means being at least partially disposed within said carrier means with said relay lens mounting means disposed within said aperture to thereby limit the relative motion between said slide means and said carrier means.
Claim 2
Dependent Claim
135 words
Apparatus for supporting the optical elements of a microscope, said apparatus comprising: a. support means, said support means including carrier receiving means; b. carrier means in the general form of a hollow tubular member at least partially disposed within said carrier receiving means, said carrier means including relay lens mounting means; and c. slide means in the general form of a hollow tubular member, said slide means including objective lens supporting means and eyepiece lens supporting means, said slide means further including an elongated through aperture located between said objective lens supporting means and said eyepiece lens supporting means, said slide means being at least partially disposed within said carrier means with said relay lens mounting means disposed within said aperture to thereby limit the relative motion between said slide means and said carrier means.
Claim 3
Dependent Claim
164 words
Apparatus for supporting the optical elements of a microscope, said apparatus comprising: a. support means, said support means including carrier receiving means; b. carrier means in the general form of a hollow tubular member at least partially disposed within said carrier receiving means, said carrier means having relay lens mounting means disposed therein; c. means supported between said carrier means and said carrier receiving means for centering said carrier means within said carrier receiving means; and d. slide means in the general form of a hollow tubular member, said slide means including means for supporting an objective lens means and means for supporting an eyepiece lens means, said slide means further including a through aperture located between said objective lens supporting means and said eyepiece lens supporting means, said slide means being at least partially disposed within said carrier means with said relay lens mounting means disposed within said aperture to thereby limit the relative motion between said slide means and said carrier means.
Claim 4
Dependent Claim
164 words
Apparatus for supporting the optical elements of a microscope, said apparatus comprising: a. support means, said support means including carrier receiving means; b. carrier means in the general form of a hollow tubular member at least partially disposed within said carrier receiving means, said carrier means having relay lens mounting means disposed therein; c. means supported between said carrier means and said carrier receiving means for centering said carrier means within said carrier receiving means; and d. slide means in the general form of a hollow tubular member, said slide means including means for supporting an objective lens means and means for supporting an eyepiece lens means, said slide means further including a through aperture located between said objective lens supporting means and said eyepiece lens supporting means, said slide means being at least partially disposed within said carrier means with said relay lens mounting means disposed within said aperture to thereby limit the relative motion between said slide means and said carrier means.
Claim 5
Dependent Claim
33 words
The apparatus according to claim 2 further including cooperative means provided on both said carrier means and said carrier receiving means for permitting relative movement between said carrier means and said support means.
Claim 6
Dependent Claim
27 words
The apparatus according to claim 2 further including means supported between said carrier means and said slide means for centering said slide means within said carrier means.
Claim 7
Dependent Claim
210 words
Apparatus for supporting the optical elements of a microscope, said apparatus comprising: a. support means, said support means including carrier receiving means; b. carrier means in the general form of a hollow tubular member at least partially disposed within said carrier receiving means, said carrier means having relay lens mounting means disposed therein; c. means supported between said carrier means and said carrier receiving means for centering said carrier means within said carrier receiving means; d. cooperative means provided on both said carrier means and said carrier receiving means for permitting relative movement between said carrier means and said support means; e. slide means in the general form of a hollow tubular member, said slide means including means for supporting an objective lens means and means for supporting an eyepiece lens means, said slide means further including a through aperture located between said objective lens supporting means and said eyepiece lens supporting means, said slide means being at least partially disposed within said carrier means with said relay lens mounting means disposed within said aperture to thereby limit the relative motion between said slide means and said carrier means; and f. means supported between said carrier means and said slide means for centering said slide means within said carrier means.
Claim 8
Dependent Claim
210 words
Apparatus for supporting the optical elements of a microscope, said apparatus comprising: a. support means, said support means including carrier receiving means; b. carrier means in the general form of a hollow tubular member at least partially disposed within said carrier receiving means, said carrier means having relay lens mounting means disposed therein; c. means supported between said carrier means and said carrier receiving means for centering said carrier means within said carrier receiving means; d. cooperative means provided on both said carrier means and said carrier receiving means for permitting relative movement between said carrier means and said support means; e. slide means in the general form of a hollow tubular member, said slide means including means for supporting an objective lens means and means for supporting an eyepiece lens means, said slide means further including a through aperture located between said objective lens supporting means and said eyepiece lens supporting means, said slide means being at least partially disposed within said carrier means with said relay lens mounting means disposed within said aperture to thereby limit the relative motion between said slide means and said carrier means; and f. means supported between said carrier means and said slide means for centering said slide means within said carrier means.
