Abstract

The invention discloses an eccentric adjusting device which comprises a bearing device, a moving device, eccentric adjusting assemblies, a lens module and a base, the moving device is arranged on the base, the bearing device is arranged above one end of the base, the eccentric adjusting assemblies are arranged around the bearing device and fixed to the base, and the lens module is fixed to the moving device. According to the device, the eccentric adjusting assemblies ensure that the adjusted aspherical lens is good in follow-up performance, high in adjusting precision and high in efficiency, a downward pressing force is applied to the adjusted aspherical lens, and the lens cannot float. The problems that according to an existing eccentric aligning technology, a clamping sleeve with the same shape as a lens is used for clamping the lens, and then an X axis and a Y axis of a sliding platform are used for adjusting the position of an aspheric lens of an adjusted group, the machining requirement for the adjusting clamping sleeve is high, and the follow-up performance of movement of the adjusted aspheric lens is poor, and thus adjustment time is relatively long and the adjusted aspherical lens is easy to float are solved.

Description

technical field [0001] The invention relates to the field of optical adjustment, in particular to an eccentric adjustment device. Background technique [0002] In the optical industry, the lens is an indispensable part. It has superior optical properties, light transmittance and mechanical and chemical properties, and has a constant refractive index and stable physical and chemical properties. However, in the optical system, each lens will inevitably have an optical axis shift. The eccentricity of the aspheric lens in the optical system has the greatest impact on the imaging quality, thereby reducing the contrast of the entire optical system, deteriorating resolution and clarity. become bad, and even cause the optical system to fail. In order to improve the imaging quality of the optical system, the optical decentering adjustment is usually performed on the sensitive aspheric lens. [0003] The existing eccentric centering technology is to use a ferrule with the same shape...
