Abstract

The invention discloses an optical path regulating and illuminating device. The optical path regulating and illuminating device comprises a tube lamp, a base and an optical bench guide rail, wherein the tube lamp is cylindrical, the end face of the head portion of the tube lamp is circular, a laser device is arranged in the position of the circle center, a set of LED lamps are evenly distributed around the laser device, the tube lamp is connected with the base through a stand rod at the bottom of the tube lamp, the base is arranged on the optical bench guide rail, a transverse movement rotary knob and a height regulating rotary knob are arranged on the base, and the laser device is a cross curve laser device. Coaxial regulation of an optical path is achieved through cross-curve-shaped laser rays emitted by the laser device, the LED lamps serve as an experiment light source, and the optical path regulating and illuminating device is simple in structure, practical and convenient to use and has both the function of an energy-saving light source and the function of optical path regulation.

Description

technical field [0001] The invention belongs to the field of optical experimental instruments, in particular to an optical path adjustment and lighting device. Background technique [0002] When performing optical experiments such as lens focal length measurement on the optical bench, the coaxial adjustment of the lens and other optical devices placed on the guide rail of the optical bench must be performed to ensure accurate imaging. The method of visual inspection is generally used for coaxial adjustment, and the center of each optical device is at the same height and on the same straight line as the guide rail. This method of visual inspection is generally not accurate enough, which often affects the image quality, and sometimes even cannot find the image. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an optical path adjustment and lighting device that can be used not only as a light source but also for opt...
