1results about How to "Guaranteed clear imaging" patented technology

The application relates to the technical field of optical systems, and provides a high-magnification line scanning imaging system and an imaging device, which solve the problem of small depth of field of an existing high-magnification line scanning imaging system, and comprise object surface one and object surface two, a first lens group arranged in sequence from the object side to the image side along the optical axis, the optical power of the first lens group being positive; a diaphragm; a second lens group, the optical power of the second lens group being negative, and a light splitting prism; the object surface one is imaged on the image surface one after sequentially passing through the first lens group, the diaphragm, the second lens group and the light splitting prism and being subjected to defocusing treatment; and the object surface two is imaged on the image surface two after sequentially passing through the first lens group, the diaphragm, the second lens group and the light splitting prism and being subjected to defocusing treatment. The application can expand the depth of field without assembling other devices, reasonably distribute the optical power, better balance the aberration, realize high magnification and high resolution, and guarantee clear imaging in a large range.
