Abstract
Abstract A method for forming a lens at an end portion of an optical apparatus, such as an optical fiber assembly, a fiber optical CRT or an LED array, which method comprises a dipping step wherein the end portion of the optical apparatus is dipped into an unsolidified photo-setting resin and a lighting step wherein the photo-setting resin is solidified according to an intensity distribution of the light outputted from the optical apparatus. Further, an optical information processing apparatus and an optical signal transmission apparatus have a lens array formed by the above method.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
78 words
A method for forming a lens at an end portion of an optical fiber, which comprises the steps of: dipping one end of the optical fiber into an unsolidified photo-setting resin; and solidifying the photo-setting resin adjacent to said one end of the optical fiber by exposing said adjacent photo-setting resin by a light which is transmitted through the optical fiber and outputted from said one end while said one end is disposed in said unsolidified photo-setting resin.
Claim 2
Independent Claim
78 words
A method for forming a lens at an end portion of an optical fiber, which comprises the steps of: dipping one end of the optical fiber into an unsolidified photo-setting resin; and solidifying the photo-setting resin adjacent to said one end of the optical fiber by exposing said adjacent photo-setting resin by a light which is transmitted through the optical fiber and outputted from said one end while said one end is disposed in said unsolidified photo-setting resin.
Claim 3
Dependent Claim
50 words
A method for forming a lens at an end portion of an optical fiber according to claim 1, wherein the lens formed at the one end of the optical fiber is formed into a convex lens because of an intensity distribution of the light inputted from the one end thereof.
Claim 4
Dependent Claim
45 words
A method for forming a lens at an end portion of an optical fiber according to claim 1, wherein a plurality of optical fibers are arranged in a predetermined configuration, and one ends of these optical fibers are simultaneously dipped into the unsolidified photo-setting resin.
Claim 5
Dependent Claim
50 words
A method for forming a lens at an end portion of an optical fiber according to claim 2, wherein the lens is formed by exposing the photo-setting resin which has a different photosensitive with respect to a wavelength of a light having a different energy with respect to each wavelength.
Claim 6
Dependent Claim
54 words
A method for forming a lens at an end portion of an optical fiber according to claim 2, wherein the lens is formed of the photo-setting resin which has a different photosensitivity with respect to each wavelength in a fiber optical CRT whose brightness differs with respect to each wavelength of a light therefrom.
Claim 7
Independent Claim
80 words
A method for forming a lens array at an end portion of an LED array, which comprises the steps of: dipping the end portion of the LED array into an unsolidified photo-setting resin; solidifying the photo-setting resin adjacent to said end portion of the LED array by exposing said adjacent photo-setting resin by a light which is generated by the LED array and outputted from said end portion thereof while said one end is disposed in said unsolidified photo-setting resin.
Claim 8
Independent Claim
80 words
A method for forming a lens array at an end portion of an LED array, which comprises the steps of: dipping the end portion of the LED array into an unsolidified photo-setting resin; solidifying the photo-setting resin adjacent to said end portion of the LED array by exposing said adjacent photo-setting resin by a light which is generated by the LED array and outputted from said end portion thereof while said one end is disposed in said unsolidified photo-setting resin.
Claim 9
Dependent Claim
50 words
A method for forming a lens at an end portion of an LED array according to claim 6, wherein each lens formed at the one end of the LED array is formed into a convex lens because of an intensity distribution of the light inputted from the one end thereof.
Claim 10
Dependent Claim
50 words
A method for forming a lens at an end portion of an LED array according to claim 7, wherein the lens is formed by exposing the photo-setting resin which has a different photosensitivity with respect to a wavelength of a light having a different energy with respect to each wavelength.
Claim 11
Dependent Claim
54 words
A method for forming a lens at an end portion of an LED array according to claim 7, wherein the lens is formed of the photo-setting resin which has a different photosensitivity with respect to each wavelength in the fiber optic CRT whose brightness differs with respect to each wavelength of a light therefrom.
Claim 12
Dependent Claim
51 words
A method for forming a lens array at an end portion of an LED array according to claim 7, wherein the lens is formed by exposing the photo-setting resin which has a different photosensitivity with respect to a wavelength of a light having a different energy with respect to each wavelength.
Claim 13
Dependent Claim
56 words
A method for forming a lens array at an end portion of an LED array according to claim 7, wherein the lens is formed of the photo-setting resin which has a different photosensitivity with respect to each wavelength in a fiber optic CRT whose brightness differs with respect to each wavelength of a light emitted therefrom.
