Abstract

The invention discloses a high-precision optical lens eccentricity adjusting structure and method. The high-precision optical lens eccentricity adjusting structure comprises a lens body, at least twolantern rings, a lantern ring fixing piece, a plurality of lens assemblies and a lens fixing piece. A lens mounting hole is formed in the lens body; the at least two lantern rings are positioned in the lens mounting hole, are eccentrically arranged with the lens mounting hole, and are sequentially distributed along the axis direction of the lens mounting hole; the lantern ring fixing piece is usedfor fixing the lantern rings and the lens body; the plurality of lens assemblies are respectively arranged in the lantern rings and are movably matched with the lantern rings; and the lens fixing piece is used for fixing the lens assemblies and the lens main body. The cost of the high-quality optical imaging system is reduced, maintenance and replacement are convenient, and part interchangeability is excellent.

Description

technical field [0001] The present application relates to the field of optical imaging equipment, in particular to a high-precision optical lens eccentricity adjustment structure and method. Background technique [0002] At present, high-precision optical imaging systems, in addition to the high-precision requirements of optical lens parts, mostly use centering car technology in production, through ultra-high-precision centering cars to ensure the position and size accuracy of the optical lens axis and optical frame, plus follow-up special design The fine-tuning mechanism realizes the assembly of high-precision ultra-high-precision optical imaging system. This kind of high-precision optical imaging system requires large investment, high processing and assembly costs, difficult assembly and adjustment technology, requires high-precision special equipment, and high maintenance costs. It is only suitable for single-piece and small-quantity production. Contents of the inventio...
