US 2003/0210465 A1 · Light trap and associated light focusing assembly

Abstract

A light trap includes a light focusing assembly and a light trap assembly. The light focusing assembly includes an access member and an intermediate member. The access member has a frustoconical shape and includes a first end and a second end having a larger cross-sectional area than the first end. The intermediate member defines an internal cavity therethrough. The intermediate member also includes a first end and a second end, with the first end being in optical communication with the second end of the access member. The light trap assembly includes a housing and a conical member. The housing defines an internal cavity that opens through one end thereof. The housing is positioned relative to the intermediate member proximate the second end of the intermediate member. The conical member has a base and an opposing apex, and is disposed within the internal cavity defined by the housing.

Dependent claims

A light trap comprising:

an access member including a first end and a second end having a larger cross-sectional area than the first end;
an intermediate member including a first end and a second end, wherein said intermediate member defines an internal cavity therethrough, and wherein the first end of said intermediate member is in optical communication with said second end of said access member;
a housing defining an internal cavity that opens through one end thereof, said housing being positioned relative to said intermediate member proximate the second end of said intermediate member;
and
a conical member having a base and an opposing apex, wherein said conical member is disposed within the internal cavity defined by said housing such that the apex of said conical member extends into the internal cavity defined by said intermediate member.

A light trap comprising:

a light focusing assembly comprising:
an access member including a first end and a second end having a larger cross-sectional area than the first end;
and
an intermediate member including a first end and a second end,
wherein said intermediate member defines an internal cavity therethrough, and
wherein the first end of said intermediate member is in optical communication with said second end of said access member;
and
a light trap assembly in optical communication with said light focusing assembly, wherein said light trap assembly comprises a housing and a conical member, wherein the housing defines an internal cavity that opens through one end thereof, wherein the conical member is disposed within the enclosure such that when rays of light enter the light trap the conical member is capable of redirecting the at least one ray of light toward at least one of an internal surface of the light focusing assembly and an internal surface of the housing.
