Latest Patents

One of Thiel's latest patents is a lens system designed for document scanning. This lens system operates in conjunction with apparatuses that scan a beam of illuminating light across a document placed on a flat support. The system includes a scanning mirror that directs reflected light from the illuminated document toward an array of photodetectors. Positioned between the scanning mirror and the photodetector array, the lens system features a movable doublet lens and a fixed doublet lens. The movable doublet lens collimates the light through the lens system, while the fixed doublet lens focuses an image of the scanned document portion onto the photodetector array. Additionally, a set of six correcting lenses is arranged symmetrically with respect to a plane of symmetry between the two doublet lenses. A barrel cam and follower arrangement is incorporated to move the movable doublet lens in synchronism with the image scanning mirror, achieving optical field flattening.
