Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
An optical adapter for an endoscope to be detachably mounted on the distal end of the endoscope, said endoscope including an observation optical system and an illumination optical system, comprising: an observation optical system; an illumination optical system; and an aperture diaphragm disposed within said observation optical system of said optical adapter such that its optical axis is in agreement with that of the observation optical system of the endoscope.
Claim 2
Dependent Claim
70 words
An optical adapter for an endoscope to be detachably mounted on the distal end of the endoscope, said endoscope including an observation optical system and an illumination optical system, comprising: an observation optical system; an illumination optical system; and an aperture diaphragm disposed within said observation optical system of said optical adapter such that its optical axis is in agreement with that of the observation optical system of the endoscope.
Claim 3
Dependent Claim
69 words
An optical adapter as set forth in claim 1 in which the observation optical system of said optical adapter includes first and second lenses substantially spaced along the optical axis of said optical adapter; said lenses being positioned so that a user of the endoscope is closer to the second lens than to the first lens; said aperture diaphragm being disposed between said lenses and adjacent said second lens.
Claim 4
Dependent Claim
90 words
Endoscope apparatus including an optical adapter to be detachably mounted on the distal end of an endoscope, said endoscope including an observation optical system and an illumination optical system, and said optical adapter including; an observation optical system and an illumination optical system; an aperture diaphragm disposed within the observation optical system of said optical adapter such that its optical axis is in agreement with that of the observation optical system of the endoscope; and said aperture diaphragm of said observation optical system of said optical adapter being detachably mounted.
Claim 5
Dependent Claim
90 words
Endoscope apparatus including an optical adapter to be detachably mounted on the distal end of an endoscope, said endoscope including an observation optical system and an illumination optical system, and said optical adapter including; an observation optical system and an illumination optical system; an aperture diaphragm disposed within the observation optical system of said optical adapter such that its optical axis is in agreement with that of the observation optical system of the endoscope; and said aperture diaphragm of said observation optical system of said optical adapter being detachably mounted.
Claim 6
Dependent Claim
46 words
An endoscope apparatus as set forth in claim 3 including a plurality of said aperture diaphragms each having a different F number; each of said aperture diaphragms being selectively insertable in the observation optical system of the optical adapter to provide optimum viewing of an image.
Claim 7
Dependent Claim
66 words
An endoscope apparatus as set forth in claim 3 including a plurality of said optical adapters; a plurality of said aperture diaphragms each of a different F number; a different one of said aperture diaphragms being in each of said optical adapters whereby optimum viewing of an image is obtained by mounting a selected one of said optical adapters at the distal end of said endoscope.
Claim 8
Dependent Claim
16 words
An endoscope apparatus as set forth in claim 3 in which said endoscope is a fiberscope.
Claim 9
Dependent Claim
17 words
An endoscope apparatus as set forth in claim 3 in which said endoscope is an electronic scope.
