Abstract

The invention provides a balanced optical element group, which includes an optical element, a motor and a bearing element. Wherein, the motor can drive the optical element to rotate, the carrying element is used to carry the optical element, and the carrying element is located between the optical element and the motor, and there is at least one weight balance area on the carrying element.

Description

technical field [0001] The invention relates to an optical element group, in particular to a balanced optical element group with a weight balance area. Background technique [0002] In recent years, with the advancement of science and technology, the application of optical components has also continued to develop and popularize. These optical components include changes in the wavefront of light behavior (such as grating-Grating), path turning (such as mirror-Mirror, prism -Prism, beam splitter-BS orPBS), color selection (such as color filter-Filter), polarization state selection (such as polarizer-Polarizer, wave plate-Retarder), etc. [0003] In the following, optical elements used in barcode scanners are used as representatives, such as a polygon mirror, a color wheel, or a color drum, to illustrate related technologies of such optical elements. [0004] Bar codes can mark the country of production, manufacturer, product name, production date, book classification number, ...
