PROBLEM TO BE SOLVED: To provide a Fresnel lens capable of reducing color aberration by applying a refractive optical surface and obtaining satisfactory imaging performance, and to provide a liquid crystal projector using the Fresnel lens.鈴木 憲三郎...
I definately agree now is not the time to buy. Plus, new software means bugs(sorry, seen it a thousand times, very rare to have exceptions), which means that even more wait time is in order.I would say wait 4-6 months. I know it's not a massive amount of time. During this ...
This is in addition to the long history as Graveyard of the Atlantic for the many shipwrecks around the Diamond Shoals which stretch out into the Gulf Stream. As you walk in the front door, the overwhelming display is a partial Fresnel lens from the Cape Hatteras light. During the Civil ...
VistaPower 5.0TM represents the cutting edge of what rear screen technology has to offer today. Particularly well-suited to CRT and lower output single lens projectors, the VP5TM provides chroma-correction and incredible brightness with outstanding uniformity, maximizing your projection investment. If ...
(57)< Abstract > As for Fresnel lens (10), by raising the transmission factor via the equilibrium of the loss with raizaburokeji (riser blockage) and surface reflection, in addition, it makes optimum to overhead projector (overhead projector) business by introducing the coma of Fresnel lens...
The refractive prism section ( 11 ) includes a refractive face (e) for refracting incident light and making the light exit toward the image-watching side, a plane (f) approximately parallel to the principal plane of the Fresnel lens sheet, and a connection face (g) for continuously forming...
The present invention provides a technology that makes it possible to display high-quality images by reducing a reflection loss of the image light entering the upper left and right ends of a transmissive screen. At the image generation source side of the Fresnel lens sheet, a totally reflective...
Optical properties of the piggyback lens can be configured to improve or reduce optical errors at the location on the peripheral retina. One or more surfaces of the piggyback lens can be a tone surface, a higher order aspheric surface, an aspheric Zeraike surface or a Biconic Zernike surface...
The solar thermal power plant has solar concentrators, which have a Fresnel lens and normal lens, where the solar thermal power plant has a pipe for a heat transfer medium. The pipe is provided on its inner side, facing the heat transfer medium, in a section with a boundary layer swirling...
and a refractive face (e) on which the light that has exited from the exit face is refracted and then guided to the image-viewing side of the Fresnel lens sheet ( 6 ), are provided in the range where the incident angle of the incoming light becomes equal to or greater than approximatel...
