Abstract:
PROBLEM TO BE SOLVED: To provide a microscopic observation apparatus for directly irradiating supply passes with UV and performing UV-sterilization, dispensing with a process of heating the inside walls of pure water supply/recovery passes arranged in a lens barrel for an objective lens and a process of making medical fluid flow in the passes. SOLUTION: At the bright field observation, a half mirror 7 is located on the position of the optical axis (L1) of the liquid-immersion objective lens 8, and nearly half the UV emitted from an illuminating optical source 2 is vertically emitted on a wafer W. At the sterilization, a reflection mirror 30 is shifted to the optical axis (L1) of the liquid-immersion objective lens 8. Regarding the UV emitted from the illuminating optical source 2, the central UV never advance toward the liquid-immersion objective lens 8 due to the round hole 30a of the reflection mirror 30. On the other hand, the UV reflected by the ambient mirror surface 30b advances along the center axis (L2) of the pure water supply/recovery passes 21 and 22, then, enters the pure water supply/recovery passes 21 and 22 through a cover glass 25, then, the pure water PW in each pass is sterilized.

Abstract:
A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, the UV light from the UV LEDs is generated internal to a housing and is optically coupled to a transparent or translucent surface touched by the human finger, such as a touch screen, a fingerprint scanner, backlit buttons or keys, a toggle of a light switch, a door knob, etc. The UV light is emitted through the touched surface to periodically disinfect the surface. A visual indication of the UV LEDs being energized is provided for safety, such as energizing visible light LEDs or a phosphor on a portion of the touched surface.
