  • Patent number: 8426800
    Abstract: Integrating optical systems and methods of use are described herein. In one embodiment, an integrating optical system comprises: a housing having a first and second portions; and a chamber having a diffuse reflective material and a volume formed within the portions when coupled together. The portions are separable to allow insertion and removal of at least one light treatable object in and out of the chamber. At least one aperture is formed in the chamber to couple to a light source and to direct light from the light source to at least a first portion of the diffuse reflective material. At least one holding structure supports the object within the volume at a location, wherein the diffuse reflective material, the aperture and the location ensure that the light is diffusely reflected to integrate the light and impact the object with substantially uniform light without movement of the object.

  • Patent number: 8404186
    Abstract: An ultraviolet flux multiplying air sterilization chamber comprises inner surfaces having a diffuse reflective behavior. The sterilization chamber includes an inlet aperture and an outlet aperture for air to flow through said chamber and a light source emitting an ultraviolet light. Due to the reflectivity of the inner surfaces of the chamber, a flux of the ultraviolet light is multiplied by reflecting multiple times from the inner surfaces of the chamber. The inlet and outlet apertures are advantageously configured to reduce the amount of light that escapes from the chamber and increase the amount of photons available in the chamber. In an exemplary embodiment, perforated end panels having diffuse, reflective interior surfaces may be provided over at least a portion of the inlet and outlet apertures.

The sterilization chamber includes an inlet aperture and an outlet aperture for air to flow through said chamber and a light source emitting an ultraviolet light. Due to the reflectivity of the inner surfaces of the chamber, a flux of the ultraviolet light is multiplied by reflecting multiple times from the inner surfaces of the chamber. The inlet and outlet apertures are advantageously configured to reduce the amount of light that escapes from the chamber and increase the amount of photons available in the chamber. In an exemplary embodiment, packed arrays of fibers, spheres, or other small particles are placed at the inlet and/or outlet to the chamber. These packed arrays provide light scattering events such that the light incident on the packed arrays reflects back with high reflectivity.
