    Technical Features:

    A.- Reliable optical platform:
    1. Use horizontal straight light path layout, no reflecting prism, light path is stable and reliable.
    2. Good designability for base, good consistency of light path.
    3. GB/T4857.18 drop test has been passed.
    4. Anti-moist ability of laser power module and the stability of electric are better.
    5. Modular construction design, maintenance is more convenient.
    6. The testing performance for small particles is improved.
    7. The all-in-one housing design, it’s dust-protected and water-proof.

    B.- Schematic diagram of optical path:
    1. Totally enclosed design of light path system, dust pollution and external light pollution can be prevented.
    2. Light path adopts lens back Fourier transform structure.
    3. Optical source adopts He-Ne laser emitter which owns better monochromaticity, high coherence, small divergence angle and good stability compared to other laser emitters, we also adopt the patent design of integrated laser emitter(patent no.: 00228952.0) which reduces heat   distortion of laser tube and external mechanical vibration.
    4. For laser emitter, except for traditional detection of output power value, we add the stability test of output power.
    5. Smoothing processing technology is used to reduce the impact of power fluctuation to measurement.
    6. Constant current limit and filling process of laser tube are used to reduce the flash frequency to the minimum.
    7. Backward detector is added, the lower limit of measurement is extended to 0.1micron.
    8. Spatial filter is fixed by powerful permanent magnet, the pinhole is not easy to shift under the disturbance of external force, so the  stability of the optical path has been greatly improved. Besides, the new designed spatial filter eliminates the laser diffraction ring   more effectively, the light background of the instrument is lower, optical energy data  is more accurate, it is helpful to improve the  testing capability for large particles.
    9. Detector array adopts unique scattered light detection around a sphere surface (DAS) (patent no.: 95223756.3), the large angle detectors  are placed in a spherical surface to get accurate focus of the large angle scattered light.

    C.-Advanced data collection and processing technology:
    1.New designed data collecting board uses 32 bit CPU from famous chip design company-ARM,the CPU has the advantages of high-effective signal processing capacity and low power consumption.
    2.Using 8-channel simultaneous sampling to sample 16 bit ADC, the sampling frequency of frame data can reach 1 kHz.
    3.Using 64-channel simultaneous sampling technology and sample & hold switch with ultralow leakage current, the full scale accuracy can  reach 0.15%.
    4.Easy to update the firmware and layout data, more convenient for maintenance and operation
    5.Offset function of electric background, it can help to get more accurate optical energy data.

    Friendly & practical software Functions:
    1. SOP standardization operating procedure function, analysis & testing process standardization
    2. Multiple distribution models:Rosin-Ramler mode, general mode, enhanced mode, Single mode
    3. Two report models:General purpose, statistics
    4. Two accumulative directions: small to large, large to small
    5. Reports in two languages:Chinese, English
    6. Data input function
    7. Reports can be exported as Word, Excel format or other text format files
    8. Multiple reports can be opened at the same time, easy to compare among reports
    9. Report items can be set/ selected according to customers’ requirements, also can be set as fixed report format.
    10. Users can define refractive index parameters by themselves, including real part and imaginary part (correspond to the absorption of sample)
    11. Automatic clear of electric background
