    TopSizer is a high-performance laser particle size analyzer that OMEC develops it with 20 years profound research and development experience. Its advantages contain wide measurement range, good repeatability, high accuracy, true test result and high reliability. OMEC represents the most advanced technology in China’s measurement and analysis area, and also represents the leader role in particle measurement area.
    Application: measure the particle distribution of the powder and latex
    Principle: Using the phenomenon of light scattering of particle, according to the distribution of scattering light energy, to calculate the size distribution of particles measured. OMEC’s instruments own the advantages of wide measurement range, good repeatability, simple operation and etc. through OMEC’s system integration and optimization for optics, mechanics, electronics and computer.

    1.Exclusive adoption of dual light resources design, red light is imported He-Ne laser with 0.6328μm wavelength; and solid blue laser with 0.466μm wavelength, it improves the resolution ratio of the nanometer particle and big particle;
    2.Shorter preheating time, stable power , and fluctuation of powder is less than 0.5%, to make the background of instrument stable, improved the resolving power of system to effective signal;
    3.Adopts the folding light path design with compact and artistic structure, and it is made of high accuracy aluminum alloy light stage to insure the light path’s steadiness;
    4.Single lens design, adopts the structure of lens back Fourier change, and breaks the restrict the pupil of the Fourier lens, to insure the maximum acceptance angle won’t be restricted by the Fourier lens caliber;
    5.Adopts Fourier lens of long focal length, effective focal length reaches 550 mm, greatly enhance the measurement capability for large particles, make the test limit of 2000 microns.
    6.Detector numbers up to 98, the forward, lateral and large Angle and backward photoelectric detector compose three-dimensional detection system, maximum detection Angle of 140°, minimum detectable Angle of 0.016°, the combination with blue light scattering signal, realized the full  Angle space range of seamless scattering light signal reception;
    7.Intelligent software control the automatic centering system, ensures the precise optical centering;
    8.Advanced circulation loop design, the use of high-power precision centrifugal pump, mixing speed can reach 4000 RPM, stepless control, highly efficient cleaning and draining capacity; ultrasonic probe built-in, the maximum power of 100w, stepless control of ultrasonic intensity.

    The Application of Patents and Proprietary Technology

    Scattered light detection around a sphere surface (DAS) The large angle detectors are placed in a spherical surface to get accurate focusing of large angle scattered light.
    Integrated laser emitter The beam expander and the pinhole filter are integrated in several concentric tubes, and then jointed into one tube with both ends enclosed. It is shock proof, easy to maintain and with stable laser output.
    Software Function:
    1.Software design modularization, invisible instrument state, humanized operation interface.
