Scope
FDQ-0301
laser particle size analyzer based on physics Fraunhofer diffraction and Mie
scattering theory basis. This theory can be simply understood as: travels in
straight lines parallel laser beam blocking particles encountered in the
communication process, the phenomenon of diffraction and scattering, and small
angle light scattering large particles, small particles of light scattering
angle is large.
Figure 1-1
shows the diffraction pattern formed by individual particles, the larger the
particle diameter, the smaller the center of the bright ring, the smaller the
particle diameter, the larger the center of the bright ring. Use photo detector
array receiving light at different angles, for the corresponding angle, its
energy is set corresponding to the diameter of the particles occurs diffraction
(scattering) caused by the respective other angle light will reflect the
strength of the corresponding diameter of the particles throughout the assembly
of particles occupies proportion, according to the intensity of the received
scattered light at different angles, you can perform anti-particle distribution
of the sample between the relative content and various size fractions.
Features
1. Up to 82 sampling channels to improve the resolution of the test
results; all the photovoltaic device fabricated on a single silicon chip, to
ensure the life of the photovoltaic array; cross-sector arrangement, increasing
the light receiving area, improves the sensitivity ;
2. micro injection method, using a peristaltic pump automatic loop
injection mode, using siphon pump automatic cycle injection mode, to meet
different customer test requirements, the instrument comes standard MS-01
micro-injector device;
3. The single lens full scale measurements, all optical components are
mounted on reinforced base before fastening a good optical system is shipped,
the instrument more stable performance;
4. Imported semiconductor lasers, has a long life, stable optical
parameters, not afraid of vibration and a series of advantages, continuous
working time of up to 24 hours, to meet user requirements for large continuous
load test.
