Laser particle size analyzer

The Truth Optics Technology team adheres to the consistent scientific spirit and technological innovation ability. Based on more than 30 years of theoretical research, technological innovation, and application experience in particle characterization, they have further improved the original LT3600 Plus and LT2200 technologies and proudly launched themLT3900Laser particle size analyzer.

The unique innovative technologies and features of LT3900 include:

●Non diffractive illumination optical module

●Ultra large angle scattering light enhancement technology

●Weak scattered light anti-interference technology

●Backscatter angle extension technique

●Refractive index calculation function

●User generated editing function for test report format

●AI optimization function

●Automatic data backup function (backup path and time can be specified by the user)

LT3900 continues to retain the excellent design of LT3600Plus and LT2200:

●Unified granularity analysis model (users do not need to select "analysis model")

●Compensation and correction techniques for anomalous changes in diffraction Airy spots (ACAD)

●Oblique measurement window technology

●Fiber optic polarization filtering technology

●Single light source avoids the problem of data stitching caused by multiple light sources

●Full range 'one mirror to the end', no need to replace lenses

●The sampling rate of scattered light can reach up to 20kHz, without missing any shape or size of scattered light information

●The ultra-high stability solid-state laser light source module using automatic constant temperature technology completely overcomes the disadvantages of long preheating time and short service life of helium neon gas lasers, greatly improving the repeatability of particle size measurement

●Fully comply with the international standard ISO13320 for laser diffraction particle size analyzer and the national standard GB/T 41949-2022

●Suitable for all injection devices produced by Truth Optics

Experimental data verification of LT3900's excellent performance

●The D50 values of the tested samples range from 40nm to 3000 μ m, with types including monodisperse latex balls and glass microspheres. A unified inversion model (which users do not need to choose, therefore it is insensitive) is used to accurately measure the D50 values in one mirror.

●According to the national standard GB/T 41949-2022 Technical Requirements for Laser Particle Size Analyzer, the D50 value of monodisperse standard sample reaches 40nm, and the upper limit based on this standard is 3000 μ m.

Summary of the * of LT3900

●Accurately measure from 10nm (D50 value 40nm) to 4000 μ m (D50 value 3000 μ m) with one mirror to the bottom

●The repeatability is excellent, and the repeatability deviation of D50 is mostly much less than 1%

●For any type of sample, including but not limited to traceable monodisperse latex microsphere standards and various user samples, a unified data analysis model is adopted to ensure the scientific nature of the measurement process
