The Method of Determining Fitting Optical Axis of Transmission Spherical Wave Lens

Abstract

The method for determining the fitting optical axis of a transmitted spherical wave lens belongs to the field of optical integration technology, and the method for determining the fitting optical axis of a transmitted spherical wave lens is determined by devices such as an interferometer, a calibration spherical mirror, a plane reflector, and a centering instrument. In this method, the incident light direction when the spherical wavefront error is the smallest is taken as the fitted optical axis direction of the transmitted spherical wave lens, and the position of the center of the spherical wavefront at this time is taken as a point of the fitted optical axis, thereby determining the fitted optical axis direction and position. Finally, the optical axis reference of the transmitted spherical wave lens is transferred to the rotation axis of the precision turntable, thereby facilitating the integration and assembly of the transmitted spherical wave lens with other optical lenses. The fitted optical axis of the transmitted spherical wave lens determined by the above method can not only reflect the influence of each surface tilt on the optical axis of the lens, but also directly reflect the influence of each surface tilt on the final optical performance of the lens. Therefore, in the above simulation The transmitted spherical wave lens working under the common optical axis can exert its best optical performance.

Background technique [0002] A high-precision optical system is usually composed of multiple groups of optical lenses. High-precision integration and assembly between optical lenses is an important link to ensure the final performance of the optical system, and the reasonable determination of the fitting optical axis of each group of optical lenses is the integration between the lenses. Prerequisites and basis for assembly. The transmitted spherical wave lens is a commonly used lens type to form a high-precision optical system.

Problems solved by technology

Using the above method to determine the fitting optical axis of the transmitted spherical wave lens can reflect the influence of each surface tilt on the ideal optical axis of the lens to a certain extent, but it cannot directly reflect the influence of each surface tilt on the final optical performance of the lens, so Transmissive spherical wave lenses operating at the above fitted optical axes may not be performing at their optimum optical performance
