Abstract
Abstract Apparatus for the isotropic emission and for the isotropic reception of light which includes a light conductor having a conical distal end with a scattering body mounted thereon in spaced relationship such that a cavity is formed between the light conductor end and the scattering body. The apparatus permits access to cavities such as hollow organs for internal laser phototherapy, for example.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
Apparatus for the isotropic emission or reception of light, said apparatus comprising a light conductor having a conical distal end surface and being provided with a coating and a scattering body having a cavity receiving the distal end of said light conductor and being connected to the coating on said light conductor, said cavity being sufficiently large so as to provide for some space between the light conductor end surface and the cavity walls of said scattering body.
Claim 2
Dependent Claim
78 words
Apparatus for the isotropic emission or reception of light, said apparatus comprising a light conductor having a conical distal end surface and being provided with a coating and a scattering body having a cavity receiving the distal end of said light conductor and being connected to the coating on said light conductor, said cavity being sufficiently large so as to provide for some space between the light conductor end surface and the cavity walls of said scattering body.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1, wherein said scattering body is a hollow sphere.
Claim 4
Dependent Claim
24 words
Apparatus according to claim 1, wherein said scattering body is a sphere having formed therein a cavity receiving the end of said light conductor.
Claim 5
Dependent Claim
18 words
Apparatus according to claim 1, wherein said light conductor end is in the form of a truncated cone.
Claim 6
Dependent Claim
44 words
Apparatus according to claim 1, wherein said light conductor has a predetermined refraction index and any medium in the space surrounding the light conductor end has a refraction index, said conductor and said medium having a refraction index ratio which is larger than 1.3.
