1. An optical fiber and lens assembly comprising:
- a housing;
an optical fiber;
means for rendering said optical fiber immobile within said housing;
lens means mounted within the housing immediately opposite the end of the optical fiber in the housing;
means for moving the said lens means within said housing toward and away from the optical fiber;
means for tilting said lens means within said housing about an axis normal to the axis of the housing in planes normal to the axis of said optical fiber;
coupling means on the end of the optical fiber in the housing;
optical fiber receptacle means fixed within said housing having an internal passage to receive the coupling means on the end of the optical fiber;
the coupling means engaged within the internal passage in the receptacle means to render said optical fiber immobile within said receptacle means and said housing.

Abstract
An optical fiber and lens assembly which comprises a housing, an optical fiber, means for rendering the optical fiber immobile within the housing, a lens, and means for moving the lens within the housing. Such an optical fiber and lens assembly enables one to provide controlled movement of the lens, independently of the optical fiber, in response to changes in the focal length of the lens, the wavelength of light, and intended usages of the light.

10. An optical fiber and lens assembly comprising:
-
a housing; an optical fiber defining a first optical axis; means for rendering said optical fiber immobile within said housing; a lens disposed on said first optical axis; and means for selectively radially, axially, and rotationally moving said lens within said housing relative to said first optical axis, said means for moving said lens within said housing comprising; lens holding means containing said lens, said lens holding means being contained within said housing; a reference plate adjacent said lens holding means whereby said lens holding means is disposed between said optical fiber and said plate; means for moving said lens holding means along said first optical axis whereby said lens holding means is moved toward or away from said optical fiber; and means for moving said lens holding means along at least one of a second axis and a third axis, said second axis lying in a plane disposed at an angle to said first axis and said third axis, said means for moving said lens holding means along said at least one of said second axis and said third axis comprising means coupled to said housing adjustably contacting said lens holding means. - View Dependent Claims (11, 12, 13, 14, 15, 16)
