Abstract
Abstract A positive and negative lens of equal power can provide the means to scan small objects being observed through a microscope if one of the lenses can be selectively decentered. The arrangement is particularly useful for microscopes having photometers that are used to analyze very small specimens, such as chromosomes, by scanning.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
52 words
A scanning system for a microscope which comprises, a pair of lenses on an optical axis each of said pair having equal and opposite power, one of said pair being movable in a plane normal to the optical axis, a gimbal mounted joy-stick to control movement of said one of said lenses.
Claim 2
Dependent Claim
52 words
A scanning system for a microscope which comprises, a pair of lenses on an optical axis each of said pair having equal and opposite power, one of said pair being movable in a plane normal to the optical axis, a gimbal mounted joy-stick to control movement of said one of said lenses.
Claim 3
Dependent Claim
22 words
The scanning system according to claim 1 wherein said lenses are adjacent and said one of said pair is a positive lens.
Claim 4
Dependent Claim
27 words
The scanning system according to claim 1 further including means to display the position of said one of said pair of lenses relative to the optical axis.
Claim 5
Dependent Claim
90 words
In combination, an optical microscope having an optical axis, an attachment for said microscope, said attachment including a positive lens and a negative lens aligned on an attachment axis, one of said positive and negative lenses being selectively movable from a normal position in a plane perpendicular to said attachment axis, a gimbal mounted stick means to move said one of positive and negative lenses in XY directions which lie in said plane and means for connecting said attachment to said microscope with said optical and attachment axes being coincident.
Claim 6
Dependent Claim
90 words
In combination, an optical microscope having an optical axis, an attachment for said microscope, said attachment including a positive lens and a negative lens aligned on an attachment axis, one of said positive and negative lenses being selectively movable from a normal position in a plane perpendicular to said attachment axis, a gimbal mounted stick means to move said one of positive and negative lenses in XY directions which lie in said plane and means for connecting said attachment to said microscope with said optical and attachment axes being coincident.
Claim 7
Dependent Claim
26 words
The combination according to claim 4 wherein said microscope has an objective, and a photometer and said means is located between said objective and said photometer.
