But in this test system, the test sample is placed in the integrating sphere, which limits the state of the sample and is not convenient for testing liquid samples
In addition, the test system does not contain light-shielding accessories. In order to eliminate the influence of external light, it needs to be used in a dark room or a dark box, and the number of integrating spheres and detectors in this detection system is large, which will increase the cost

The invention relates to an optical test system and test method. The system comprises a base, a light input unit, an integrating sphere and a reflectivity detection room, wherein the light input unitcomprises an input port as well as an input light modulator, a spectroscope and a light output port successively located behind the input port. The system also comprises an input light detector for detecting light split by the spectroscope; the integrating sphere is provided with an input hole, an output hole I and an output hole II; an output light detector is mounted corresponding to the outputhole II; the reflectivity detection room comprises a fixed rack and a lens hood covering the periphery of the fixed rack; the fixed rack is provided with a fixed groove for fixing a sample supportingrack and an optical window where light passes through; a to-be-tested article is arranged in the sample supporting rack, and the lens hood does not shield the optical window. The system is simple in equipment structure and low in cost, and the test method is convenient and rapid, is suitable for all samples which can be represented by transmittance and reflectivity parameters, and is not limited by the state of the sample, so that the system and method are wide in application range.
Description
technical field [0001] The invention belongs to the field of optical testing, and in particular relates to an optical testing system and a testing method. Background technique [0002] The existing method of testing transmittance and reflectance is to take the sample out of the solution after preparing the sample and load it on the tester for testing. There is a process of transferring the sample, especially when testing the effect of some reaction time on the transmittance and reflectance of the sample. In the test of the influence of reflectivity, it is necessary to prepare samples with different reaction times before testing. Multiple samples of the same series with different reaction times need to be prepared, resulting in wasted sample preparation time and reagent costs. Moreover, there may be differences in reagent quality, dosage, and sample itself among different samples, which increases the uncertainty of the experiment. [0003] The invention patent with applicat...
