Abstract

The invention relates to a laser focusing device for a lens during the process of manufacturing a stage lamp, comprising a guide rail, a first slide carriage, a second slide carriage and a third carriage which are arranged on the guide rail; one side of each slide carriage is respectively provided with a fixing button, so that each slide carriage can slide and be fastened on the guide rail; the third slide carriage is provided with an L-shaped support having an upper end provided with a laser emitter module which is provided with a laser; the second slide carriage is provided with a lens support above which a lens is arranged; and the first slide carriage is provided with an L-shaped support having an upper end provided with a laser receiver module which is provided with a laser receiver. The device has the advantages of convenient and simple operation, accurate and direct measurement, low cost, simplified calculation during the designing process, reduced error, improved work efficiency, and accurate measurement for both spherical lens and non-spherical lens.

Description

Technical field [0001] The invention relates to a device for measuring focal length, in particular to a lens laser focus measuring device in the manufacturing process of stage lamps, which belongs to photoelectric lighting technology. Background technique [0002] When manufacturing stage lighting, it is not only necessary to design the shell of the lighting, but also the light source components. The light source and the lens must be in a horizontal line to form a main optical axis, especially a lamp with multiple lenses, which must be composed of multiple lenses with different focal lengths, so it is necessary to accurately know the focal length of each lens. [0003] Usually, the focal point of the lens is measured when the lamp is manufactured. The original measurement method is manual measurement. Generally, the design engineer holds the curvature meter to measure the focal length, and aligns the three fulcrums on the curvature meter with the lens sphere to read the value on ...
