Multifunctional focusing test light box

Abstract

The invention relates to the technical field of camera focusing equipment, in particular to a multifunctional focusing test light box, which comprises a light box frame, a light box, a light source module, a light source module, a light source module and a light source module, and is characterized in that two opposite ends are provided with a top plate and a bottom plate; the substrate is arranged in the light box frame and is positioned between the top plate and the bottom plate; the light source module is arranged in the light box frame and located between the top plate and the substrate, the light source module comprises a light source assembly, and the light source assembly comprises light source parts with different light wave bands; the light transmitting assembly is arranged in the light box frame and located between the substrate and the light source module; the controller is arranged on the bottom plate and connected with the light source part, and an adjusting assembly for adjusting the light source part is arranged on the controller. The confocal test of the multiple lenses of the camera can be met, and the multi-band confocal test efficiency and the test accuracy of the multiple lenses are improved.

Description

technical field [0001] The application relates to the technical field of camera focusing equipment, in particular to a multifunctional focusing test light box. Background technique [0002] At present, with the development of electronic technology, the demand for various electronic products, such as cameras on mobile phones and notebook computers, is increasing, the dependence on image technology is getting higher and higher, and the pixel value of the corresponding camera is also increasing. In order to make the optical lens of the camera have an optimal imaging surface, the tester needs to adjust the focal length of the multiple lenses of the camera in different bands, but now There are devices that generally only have a light box with a single band (650NM / 850NM / 940NM) light source, which can only meet the focusing test of a single lens of the camera, and it is difficult to meet the confocal test of multiple lenses of the camera in different bands at the same time.

[0002] At present, with the development of electronic technology, the demand for cameras on various electronic products, such as mobile phones and laptop computers, is increasing, and the dependence on image technology is getting higher and higher, and the pixel value of the corresponding cameras is also getting higher and higher. The higher the higher, the higher the resolution of the images taken by the camera is, the more stringent the requirements are. In order to make the optical lens of the camera have an optimal imaging surface, the testers need to adjust the focal lengths of the multiple lenses of the camera in different bands, but now Some equipment generally only have a light box with a single-band (650NM / 850NM / 940NM) light source, which can only meet the focus test of a single lens of the camera, and it is difficult to meet the confocal test of multiple lenses of the camera in different bands at the same time. Switch the focusing equipment of different bands for confocal testing to find the best confocal. This operation is not only inefficient, but also not accurate enough
