Abstract: A fluorescence inspection spectrometer uses a stimulated light beam emitted by a light source, passes through the first collimator, the polarization beam splitter, and the objective lens, and then focuses on a test object to detect the excited fluorescence. Through the first optical filter module, the second collimator, and the reception of the photo detector, the fluorescence is converted into an output signal for fluorescence signal analysis. The feature is that the objective lens is installed on an actuator. More accurate data can be measured by fine-tuning the actuator so that the objective lens reaches its optimal focal position.

Abstract: A fluorescent auxiliary testing apparatus includes a light source module which emits a laser light to pass through a collimator, a dichroic mirror, and a first converging lens to project a testing object. The testing object emits a corresponding testing fluorescent light which passes through a filter assembly and a second converging lens and is received by a photo detector for generating a photoelectric signal. The photoelectric signal is transferred to a data processing equipment to perform test and analysis processes. The apparatus has a small size and a simple structure, and may be fabricated at a low cost.
