  • Continuous gradient cylindrical diffusion tip for optical fibers and method for using
    Patent number: 5330465
    Abstract: A diffuser tip for a fiber optic or array of fibers having a proximal end which abuts against the tip of the fiber optic or array of fibers. The diffuser tip has a cylindrical center core of transparent elastomer which contains scattering centers embedded therein. The scattering centers are distributed within the core so that the concentration of scatterers increases continuously in a direction from the proximal end of the diffuser tip to the distal end of the diffuser tip.

  • Apparatus for producing a spherical pattern of light and method of manufacture
    Patent number: 4693556
    Abstract: The present invention discloses an optical radiating apparatus constructed on one end of a light-conducting optical fiber such that, upon encountering this radiator, light is caused to leave the fiber and radiate in a spherical pattern with respect to the end of the fiber. This optical radiator is constructed such that the pattern of radiated light is nearly uniform in intensity in a spherical pattern, without areas of light intensity significantly different from the average distribution around the surface of a sphere. The present invention also discloses a method to manufacture the above-described light radiating apparatus, ensuring uniformity of light intensity and the ability to transmit relatively intense light without developing regions of optical, thermal or mechanical damage.

  • Apparatus for producing a cylindrical pattern of light and method of manufacture
    Patent number: 4660925
    Abstract: The present invention discloses an optical radiating apparatus constructed on one end of a light-conducting optical fiber such that, upon encountering this radiator, light is caused to leave the fiber and radiate in a cylindrical pattern with respect to the central axis of the fiber. This optical radiator is constructed such that the pattern of radiated light is nearly uniform in intensity in a cylindrical pattern, without areas of light intensity significantly different from the average distribution around the circumference of the cylinder. The present invention also discloses a method to manufacture the above-described light radiating apparatus, ensuring uniformity of light intensity and the ability to transmit relatively intense light without developing regions of optical, thermal or mechanical damage, and without the need to reshape the core of the optical fiber.
