Detection device of light sensing component

Abstract

The invention provides a detection device of a light sensing component. The detection device comprises a light source, a first convex lens, a second convex lens and a light sensing component, wherein the first convex lens and the second convex lens are arranged in parallel, so that the light source penetrates through the first convex lens to emit a parallel light source onto the second convex lens, and centrally focuses and irradiates the light sensing component through the second convex lens to achieve the effect of effectively testing various photoelectric characteristics of the light sensing component.

Description

【Technical field】 [0001] The invention relates to a detection device of a light-sensing component, especially a device that can irradiate a light source on the light-sensing component in a concentrated manner, so as to effectively test various photoelectric characteristics of the light-sensing component. 【Background technique】 [0002] Generally, a conventional photosensitive component detection device is usually composed of a photosensitive component and a light source module arranged at an appropriate distance on one side of the corresponding photosensitive component; the distance between the photosensitive component and the light source module can be adjusted , so that the parallel light emitted by the light source module is irradiated on the photosensitive component, so as to achieve the effect of testing the photoelectric characteristics of the photosensitive component.

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned conventional photosensitive component detection device can test the various photoelectric characteristics of the photosensitive component, it is limited by the light irradiation situation of the light source module when the light source is irradiated, so the light source module must be installed with the light Only by forming a relatively long distance between the sensor components can the light source module have the effect of simulating parallel light when irradiating, which causes problems such as setting the light irradiation distance of the light source module is too far and the light irradiation position is not easy to align.

And because the light irradiation distance is too far, it will lead to serious attenuation of light source intensity, and most of the light sources will not be able to concentrate on the photosensitive components. Unless the intensity of the light source is greatly increased, otherwise the test work will be difficult to implement; and in order to match the light source module In order to achieve the effect of simulating parallel light under the light irradiation situation, a considerable space must be used between the whole set of photosensitive component detection device and the photosensitive component to be tested, thus resulting in an increase in the cost of the testing process

[0004] Therefore, the conventional photosensitive component detection device cannot meet the needs of actual use
