Latest Patents

Negishi holds a patent for a "Projector lens system having three lens groups for image projector." This invention discloses an image projector designed to project a tri-color composite optical image onto a screen as a magnified optical image. The system separates a reading light beam emitted from a light source into three color beams—Red, Green, and Blue—using a tri-color separation and composition optical system. The separated color beams are directed onto image forming devices that correspond to each color, allowing for the reading of color images. The reflected light beams from these devices then recombine to form a composite image beam, which is projected onto the screen through a carefully arranged optical lens system.
