Abstract

The invention discloses a high-precision laser nanometer particle analyzer which comprises a computer, a first data acquisition module, a first photodiode, a first optical fiber, a first wiring terminal, a mounting plate, a convex lens, a sample chamber and a laser source, the mounting plate is arranged on one side of the convex lens, and the sample chamber is arranged on the other side of the convex lens; the laser source is opposite to the convex lens, and laser emitted by the laser source penetrates through the convex lens and irradiates the middle part of the mounting plate; the first wiring terminal is arranged at the end part of the mounting plate; a stepping motor, fan blades and concave lenses are arranged, and the concave lenses are embedded in the fan blades; when the stepping motor rotates and the concave lens covers the first wiring terminal, scattered light can be amplified, and the value of particles in the sample chamber can be obtained through calculation of the computer. When the stepping motor rotates and the convex lens deviates from the first wiring terminal, the normal measurement mode can be recovered.

Description

technical field [0001] The invention relates to a high-precision laser nanometer particle size analyzer, in particular to an optical amplification structure of the high-precision laser nanometer particle size analyzer. Background technique [0002] Because the laser particle size analyzer is not affected by many factors such as temperature change, medium viscosity, sample density and surface state, as long as the sample to be tested is evenly displayed in the laser beam, accurate test results can be obtained. It has the characteristics of fast test speed, wide range, good repeatability and accuracy, so it is widely used. The laser particle size analyzer uses the scattering effect of light generated by the laser irradiation on the micropowder particles. The difference in the number of particles causes the change of the scattering intensity. The optical signal is converted into an electrical signal through a photoelectric conversion device, thereby calculating the particle siz...
