Abstract
The invention discloses an optical test system which comprises a broadband light source generator, an upper collimator, a lower collimator, a spectrometer and a test system. The broadband light source generator is connected with the upper collimator by a first optical fiber. The lower collimator is connected with the spectrometer by a second optical fiber. The spectrometer is also electrically connected with the test system, and a holding stage is arranged between the upper collimator and the lower collimator to hold an object that is about to be tested. According to the above technical schemes, the divergent light emitted from the broadband light source generator from the optical fiber passes through the upper collimator and becomes parallel light. The parallel light is irradiated on the object to be tested on the holding stage, and is then focused by the lower collimator. Having been focused, the light beam enters the spectrometer, where the spectrometer analyzes each wavelength of the light and the light transmittance rate. At the same time, the test system controls the spectrometer, analyzes and processes the light and displays the test results.
