Abstract

Abstract A optical spotting scope in combination with an optical alignment viewer which includes a spotting scope body; a optical spotting scope lens system mounted within the spotting scope body to provide an optical axis therethrough and to further provide high power magnification of distant images within the field of view of the spotting scope lens system; a view finder body rigidly joined to the spotting scope body; and a optical viewer lens system selected, mounted and arranged within the view finder body to provide an optical axis therethrough in substantial parallel alignment with the optical axis of the spotting scope lens system so that the field of view of the viewer lens system coincides with and includes the field of view of the spotting scope lens system, the viewer lens system being substantially lower power magnification than the spotting scope lens system; whereby a distant image visible centrally within the field of view of the viewer lens system, will fall within the field of view of the spotting scope lens system.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 342 words
A sportsman's spotting scope with alignment viewer comprising in combination: a spotting scope body; a optical spotting scope lens system selected, mounted and arranged with said spotting scope body to provide an optical axis therethrough and to further provide high power magnification in the range of 15X and 80X of distant images within the field of view of said spotting scope lens system; a view finder body rigidly joined to said spotting scope body; and a optical viewer lens system selected, mounted and arranged within said view finder body to provide an optical axis therethrough in substantial parallel alignment with said optical axis of said spotting scope lens system whereby the field of view of said viewer lens system coincides with and includes the field of view of said spotting scope lens system, said viewer lens system being substantially lower power magnification than said spotting scope lens system, said lower power magnification being in the range of 1X to 6X; optical centering means mounted within said view finder body to provide a visual indication of the central region of the field of view of said viewer lens system, said optical centering means comprising a crosshair reticle mounted and arranged with said viewer lens system to superimpose a fine cross upon the view seen through said viewer lens system; adjustment means connected to said viewer lens system to adjustably vary the central point of the field of view thereof to coincide with and overlie the field of view of said spotting scope lens system, said adjustment means including a pair of eccentric rings operably interconnecting said optical axis of said viewer lens system and said view finder body to vary the alignment of said optical axis of said viewer lens system with respect to said optical axis of said spotting scope lens system; whereby a distant image visible centrally within the field of view of said viewer lens system will fall within the field of view of said spotting scope lens system to aid in aligning the spotting scope with a distant image.
Claim 2
Dependent Claim 342 words
A sportsman's spotting scope with alignment viewer comprising in combination: a spotting scope body; a optical spotting scope lens system selected, mounted and arranged with said spotting scope body to provide an optical axis therethrough and to further provide high power magnification in the range of 15X and 80X of distant images within the field of view of said spotting scope lens system; a view finder body rigidly joined to said spotting scope body; and a optical viewer lens system selected, mounted and arranged within said view finder body to provide an optical axis therethrough in substantial parallel alignment with said optical axis of said spotting scope lens system whereby the field of view of said viewer lens system coincides with and includes the field of view of said spotting scope lens system, said viewer lens system being substantially lower power magnification than said spotting scope lens system, said lower power magnification being in the range of 1X to 6X; optical centering means mounted within said view finder body to provide a visual indication of the central region of the field of view of said viewer lens system, said optical centering means comprising a crosshair reticle mounted and arranged with said viewer lens system to superimpose a fine cross upon the view seen through said viewer lens system; adjustment means connected to said viewer lens system to adjustably vary the central point of the field of view thereof to coincide with and overlie the field of view of said spotting scope lens system, said adjustment means including a pair of eccentric rings operably interconnecting said optical axis of said viewer lens system and said view finder body to vary the alignment of said optical axis of said viewer lens system with respect to said optical axis of said spotting scope lens system; whereby a distant image visible centrally within the field of view of said viewer lens system will fall within the field of view of said spotting scope lens system to aid in aligning the spotting scope with a distant image.
Claim 3
Dependent Claim 28 words
The spotting scope with alignment viewer as in claim 1, said spotting scope body and said view finder body being intergrally formed to rigidly fix the alignment therebetween.
Claim 4
Dependent Claim 26 words
The spotting scope with alignment viewer as in claim 1 wherein the magification of said viewer lens system falls in the range of 3X to 4X.
Claim 5
Dependent Claim 41 words
The spotting scope with alignment viewer as in claim 1 wherein said spotting scope lens system includes an ocular eyepiece and said viewer lens system includes an ocular eyepiece in close proximity to said eyepiece of said spotting scope lens system.
