Problems solved by technology

As an important optical element in the optical system, the position accuracy of the lens has a great impact on the optical path directly. In the prior art, errors caused by optical path calculation, machining technology and assembly technology often cause The deviation of the optical system on the optical path will affect the performance of the optical system, making the consistency of the optical axis of the entire optical system poor
[0003] A projector is a device that can project images or videos onto a screen. The key to determining the quality of projection often lies in the optical system of the projector. The projection optical system in the prior art has the following problems: due to the poor consistency of the optical axis , causing loss of light energy, which may result in missing projected images

Description

technical field [0001] The invention relates to an optical element adjustment device and an optical system with the optical element adjustment device, in particular to a lens adjustment device and a projection optical system. Background technique [0002] The optical system is a system composed of various optical elements in a certain order. It is generally used for imaging or optical processing. It can meet a series of requirements and obtain a high-quality optical system that meets the needs. It is not a simple combination of several optical elements. The parameters of each optical element must be reasonably configured and properly determined. As an important optical element in the optical system, the position accuracy of the lens has a great impact on the optical path directly. In the prior art, errors caused by optical path calculation, machining technology and assembly technology often cause The deviation of the optical system on the optical path further affects the pe...
