  • OPTICAL MULTILAYER THIN-FILM SYSTEM
    Publication number: 20060285208
    Abstract: An optical multilayer thin-film system (11) includes a number of high refractive index layers (13), and a number of low refractive index layers (14) alternately laminated with the high refractive index layers. Each high refractive index layer has an optical thickness larger than that of each low refractive index layer. When such a multilayer thin-film system is applied to an optical element, spectral shift with respect to variation of the incident light angle is significantly reduced.

  • Heat radiation device capable of resisting light leakage
    Publication number: 20060274280
    Abstract: A heat radiation device capable of blocking light leakage, which applied to a projection system with at least a light source, includes a fan wheel, a fan frame and a stop part. The fan frame defines a flow passage to receive a hub seat for being attached with the fan wheel. The fan wheel has a plurality of fan blades extending outward from the hub radially with each of the fan blades spacing apart from each other and overlapping to another one of the fan blades next to it. A clearance is kept between the flow passage and the fan wheel. The stop part is disposed at the rim of the fan frame to extend toward the center of the fan frame with a length at least covering the clearance between the flow passage and the fan wheel. Hence, light projecting to the heat dissipation device from the light source is shaded by way of the stop part and the overlapped fan blades to avoid light leakage.
