IIOMEC Opsizer Plus Laser Particle Size AnalyzerWorking Principle:

A beam of parallel light encounters obstacle particles during propagation, and the light wave will undergo scattering (diffraction) deflection. The deflection angle is related to the size of the particles, and the scattering (diffraction) phenomenon can be described by the "Mie scattering theory". The larger the particle size, the smaller the angle of light wave deflection; The smaller the particle size, the greater the angle of light wave deflection. Laser particle size analyzer utilizes the scattering phenomenon of particles on light to calculate the particle size distribution of the measured particles based on the distribution of scattered light energy.

OMAX combines advanced technologies from both domestic and international sources, integrating and optimizing optical, algorithmic, mechanical, electronic, and computer systems to provide the OMAX laser particle size analyzer with advantages such as good repeatability, wide dynamic measurement range, and simple and convenient operation.

3、 Advanced optical system

The Topsizer Plus laser particle size analyzer adopts a dual light source design, with the main red light source being an imported helium neon laser with a wavelength of 0.6328 μ m; And there is a semiconductor blue light auxiliary light source with a wavelength of 0.466 μ m, which improves the resolution of nanoscale particles and a small amount of large particles. In domestic laser particle size analyzers, the red and blue dual color light source technology is adopted by OMAX.

Imported high-performance helium neon laser and power supply

We use imported brand helium neon lasers known for their long lifespan, low noise, and high stability, as well as matching laser power supplies, to provide ideal optical quality polarized light sources for the instrument. On the basis of the stable wavelength brought by the gas laser itself, the Topsizer Plus laser particle size analyzer adopts a high-performance light source system that has the necessary optical characteristics of power stability, short preheating time, high polarization ratio and stability, and high mode purity for high-performance laser particle size analyzers. Ensure that the instrument can maintain stable operation in different working environments and provide accuracy performance without calibration.

Linear optical path design

The optical path system of Topsizer Plus laser particle size analyzer adopts a closed linear optical path design, which eliminates stray light caused by redundant reflective optical components and dust pollution interference. At the same time, a high-precision all aluminum alloy optical platform is used to ensure stable and reliable optical path.

Post Fourier Transform Single Lens Design

Single lens design, using a Fourier transform structure behind the lens, breaks through the pupil constraint of Fourier lenses, allowing the scattered light receiving angle to be unrestricted by the Fourier lens aperture; Moreover, the reduction of refractive and reflective surfaces in the single lens optical path can further reduce the background noise during instrument operation to a low level, improving the signal-to-noise ratio during instrument measurement.

Fourier lens with long focal length

The Topsizer Plus laser particle size analyzer uses a Fourier lens with a longer focal length, which increases the distance from the measurement window to the photodetector plane (i.e. the effective focal length), allowing the photodetector to accurately detect scattered light signals with smaller scattering angles, greatly enhancing the instrument's testing ability for large particles. The instrument's measurement upper limit reaches 3600 μ m.

Reasonably distributed and highly sensitive imported photodetectors

The Topsizer Plus laser particle size analyzer photodetector is a specially customized imported photodetector that ensures high resolution and sensitivity of the instrument. There are up to 103 detection channels, consisting of forward, lateral, large angle, and backward photodetectors forming a three-dimensional detection system, with a detection angle range of up to0.016-140 degrees. By combining blue light scattering signals, seamless reception of scattered light energy signals across the entire spatial angle range has been achieved, effectively ensuring comprehensive and accurate acquisition of particle scattered light energy information.
