Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
147 words
A self-contained microscope system for operating in ambient light, comprising: a base including an integral stage section for holding a specimen to be viewed and an inner cavity having access to an external ambient light source, said stage section defining a stage hole; an eyepiece section adjustably mounted to said base for holding a lens, said eyepiece section aligned with said stage hole; means for finely adjusting the position of said eyepiece section relative to said base to adjust the focus of said lens; an optical wave guide light collector including a collector element and a light pipe having a first, enlarged end interconnected with said collector element and a second, smaller end for alignment with said stage hole for transmitting the collected light to the specimen being viewed; and means in said cavity for holding said collector element for disposition in a field of ambient light.
Claim 2
Dependent Claim
147 words
A self-contained microscope system for operating in ambient light, comprising: a base including an integral stage section for holding a specimen to be viewed and an inner cavity having access to an external ambient light source, said stage section defining a stage hole; an eyepiece section adjustably mounted to said base for holding a lens, said eyepiece section aligned with said stage hole; means for finely adjusting the position of said eyepiece section relative to said base to adjust the focus of said lens; an optical wave guide light collector including a collector element and a light pipe having a first, enlarged end interconnected with said collector element and a second, smaller end for alignment with said stage hole for transmitting the collected light to the specimen being viewed; and means in said cavity for holding said collector element for disposition in a field of ambient light.
Claim 3
Dependent Claim
25 words
The microscope of claim 1 further including means, disposed in said base, for holding the smaller end of said light pipe proximate said stage hole.
Claim 4
Dependent Claim
30 words
The microscope of claim 2 in which said means for holding the smaller end of said light pipe includes guide means for centering said smaller end at said stage hole.
Claim 5
Dependent Claim
19 words
The microscope of claim 3 in which said guide means releasably holds said smaller end of said light pipe.
Claim 6
Dependent Claim
19 words
The microscope of claim 4 in which said light pipe is flexible to facilitate removal from said guide means.
Claim 7
Dependent Claim
23 words
The microscope of claim 1 in which said means for holding the enlarged end of said light pipe releasably holds said light pipe.
Claim 8
Dependent Claim
27 words
The microscope of claim 6 in which said light pipe is flexible to facilitate removal from said means for holding the enlarged end of said light pipe.
Claim 9
Dependent Claim
16 words
The microscope of claim 1 in which said second, enlarged end is generally conical in shape.
Claim 10
Dependent Claim
16 words
The microscope of claim 4 in which said conical shape has an angle of approximately 45°.
Claim 11
Dependent Claim
33 words
The microscope of claim 1 in which said collector element directs ambient light from a wide field of view to the enlarged end of the light pipe for concentration at the stage hole.
Claim 12
Dependent Claim
18 words
The microscope of claim 1 in which said collector element has an angle of admittance of approximately 45°.
Claim 13
Dependent Claim
13 words
The microscope of claim 1 in which said collector element is a lens.
Claim 14
Dependent Claim
21 words
The microscope system of claim 1 in which said collector element is fixed to said enlarged end of the light pipe.
Claim 15
Dependent Claim
14 words
The microscope of claim 1 in which said cavity communicates with said stage hole.
Claim 16
Dependent Claim
15 words
The microscope of claim 1 in which said light collector is disposed within said cavity.
Claim 17
Dependent Claim
25 words
The microscope of claim 1 in which the second, smaller end of said light pipe is believed to concentrate the ambient light on the specimen.
Claim 18
Dependent Claim
28 words
The microscope of claim 1 in which the second, smaller end of said light pipe has an end surface with a matte finish for diffusing the ambient light.
Claim 19
Dependent Claim
197 words
A self-contained microscope system for operating in ambient light, comprising: a base including an integral stage section for holding a specimen to be viewed said stage section defining a stage hole; an inner cavity in said base in communication with said stage hole and having access to an external ambient light source; an eyepiece section adjustably mounted to said base for holding a lens, said eyepiece section aligned with said stage hole; means for finely adjusting the position of said eyepiece section relative to said base to adjust the focus of said lens; an optical wave guide light collector including a flexible light pipe having a first, enlarged end and a second, smaller end for alignment with said stage hole, said light pipe for transmitting ambient light to the specimen being viewed; guide means in said cavity for removably holding the smaller end of said light pipe proximate and centered at said stage hole; a wide-angle collector element attached to said first, enlarged end for collecting ambient light and concentrating it in said light pipe; and means in said cavity for removably holding said collector element in said cavity for disposition in a field of ambient light.
Claim 20
Dependent Claim
197 words
A self-contained microscope system for operating in ambient light, comprising: a base including an integral stage section for holding a specimen to be viewed said stage section defining a stage hole; an inner cavity in said base in communication with said stage hole and having access to an external ambient light source; an eyepiece section adjustably mounted to said base for holding a lens, said eyepiece section aligned with said stage hole; means for finely adjusting the position of said eyepiece section relative to said base to adjust the focus of said lens; an optical wave guide light collector including a flexible light pipe having a first, enlarged end and a second, smaller end for alignment with said stage hole, said light pipe for transmitting ambient light to the specimen being viewed; guide means in said cavity for removably holding the smaller end of said light pipe proximate and centered at said stage hole; a wide-angle collector element attached to said first, enlarged end for collecting ambient light and concentrating it in said light pipe; and means in said cavity for removably holding said collector element in said cavity for disposition in a field of ambient light.
