The present invention discloses an optical measurement system and an optical imaging system. The optical measurement system comprises a lens module, a light source module and a photosensitive element, wherein the lens module comprises a first lens assembly and a second lens assembly, the first lens assembly is arranged between the second lens assembly and an object side, the first lens assembly and the second lens assembly co-have an optical axis, the light source module is arranged between the first lens assembly and the second lens assembly and is provided with an opening, the optical axis penetrates through opening, the light source module is used for emitting light to the object side through the first lens assembly, the photosensitive element is positioned on the lens module side opposite to the object side, and is used for receiving the object light from the object side, wherein the object light passes through the lens module and the opening of the light source module. In the optical measurement system of the present invention, the light source module can be close to the optical axis as more as possible in the case of no influence on the object light so as to provide the light close to the optical axis.
Description
technical field [0001] The invention relates to an optical measuring system and an optical imaging system. Background technique [0002] In recent years, due to the reduction in the size of components, many automated high-precision testing equipment have been developed to detect various tiny parts and even various samples. These detection devices obtain the information of the sample to be tested by detecting the light reflected by the sample to be tested. Among them, how to arrange both the light source and the photosensitive element on the optical path of the detection device is an important issue. [0003] In some detection devices, a beam splitter is usually provided to couple the light transmission path of the light source and the transmission path of the light received by the photosensitive element, so that the reflected light can be effectively captured by the photosensitive element. However, the setting of the beam splitter often reduces the light intensity, resulti...
