Three-lens optical system (patented technology)

The optical path is purer and the background level is lower, enhancing measurement accuracy and instrument sensitivity. The 110-mm large-aperture lens expands the detection angle, while the increased number of detectors improves resolution. The three-lens optical system comprises an imported high-power fiber-optic laser source, a patented Fourier lens, a filtering lens, a standard Fourier-transform lens, a forward detector, and a lateral detector. The fiber-optic interface connects to a high-power fiber laser; the Fourier lens transforms the diverging laser beam into a converging one. The filtering lens primarily eliminates scattered stray light, ensuring that the converged light on the optical path is even purer, thereby reducing the instrument’s background level and improving measurement accuracy and sensitivity. When a sample is illuminated by the laser beam, it generates scattered light signals. The standard Fourier-transform coated lens focuses these scattered signals onto the detector, resulting in a stronger and more sensitive detection signal.

The three-lens optical system consists of an imported high-power fiber-optic output laser, a patented Fourier lens, a filtering lens, a standard Fourier transform lens, a forward detector, and a lateral detector. The fiber optic interface connects to a high-power fiber laser; the Fourier lens transforms the diverging laser beam into a converging one. The filtering lens primarily eliminates stray ambient light, ensuring that the focused light on the optical path is purer, thereby reducing background noise and enhancing the instrument's accuracy and sensitivity. When the sample under test is illuminated by the laser beam, it generates scattered light signals. The standard Fourier-transform coated lens then focuses these scattered signals onto the detector, resulting in a stronger and more sensitive detection signal.
