Latest Patents

Yamada holds a patent for an optical illumination device. This device reflects and condenses light from a mercury-arc lamp using a light reflecting and condensing member. The design allows for the reflection and deflection of light, which is then transferred to a relay-lens system through a collimator lens or input lens, band-pass filter, and fly-eye lens. Additionally, gas that has had impurities removed by a filter is circulated around the optical elements. This process separates the optical elements from air that contains materials causing clouding, thereby restraining the clouding of the optical elements. Furthermore, the reflectance of the light reflecting and condensing member is minimized for light in the absorption band of sulfur dioxide to prevent clouding.
