LT2100 Series Laser Particle Size Analyzer
Product Overview
The LT2100 Series Laser Particle Size Analyzer is a high-performance particle size measurement system based on laser diffraction and static light scattering technology. It is designed for accurate and efficient particle size distribution analysis of powders, suspensions, and other particulate materials.
The LT2100 series uses a newly optimized optical system, improved optical models, and advanced inversion algorithms to reduce the influence of Anomalous Change of Airy Disk (ACAD) on particle size analysis results. The system uses a unified particle size analysis mode, eliminating the need for users to select different analysis modes according to particle size.
The series provides particle size measurement ranges of 0.1–800 μm for LT2100 and 0.05–1200 μm for LT2100 Plus, covering a wide range of laboratory and industrial particle size analysis applications.
The optical measurement system complies with ISO 13320 requirements for laser diffraction particle size analysis and incorporates multiple patented technologies for optical filtering, diffraction correction, inverse Fourier optical configuration, large-angle detection, liquid-level control, and optical signal stabilization.

Key Features
• Wide Particle Size Measurement Range
LT2100 provides a measurement range of 0.1–800 μm, while LT2100 Plus extends the range to 0.05–1200 μm.
The wide measurement range allows the system to analyze fine powders, micron-scale particles, and relatively coarse particulate materials without changing lenses.
• Advanced Laser Diffraction Technology
The system uses laser diffraction/static scattering technology together with optimized optical models and inversion algorithms.
The full-range Mie theory and Fraunhofer theory can be selected according to analytical requirements, providing a flexible approach for particle size distribution analysis.
• ACAD Compensation and Correction Technology
LT2100 incorporates technology for compensating and correcting the Anomalous Change of Airy Disk (ACAD) effect.
This helps reduce the influence of abnormal Airy disk behavior on particle size calculation and improves the reliability of particle size distribution results.
• Polarization Filtering Technology
The patented polarization filtering technology improves optical signal quality and helps suppress unwanted optical interference during measurement.
• Inverse Fourier Optical Configuration
The system adopts an oblique-incidence inverse Fourier optical configuration, providing an optimized optical path for wide-range particle size measurement.
• Large-Angle Detection Array
The grating-type large-angle detection array technology expands the optical detection capability and supports measurement of fine particles requiring large-angle scattering information.
• Unified Particle Size Analysis Mode
LT2100 uses a unified particle size analysis mode, eliminating the need to manually select different analysis modes according to the particle size range.
This simplifies operation and improves measurement consistency.
• High-Speed Real-Time Measurement
The optical measurement system provides a real-time measurement rate of up to 2 kHz, enabling rapid acquisition of measurement data and supporting dynamic observation of particle size changes.
• Stable Solid-State Laser Source
The system uses a high-stability semiconductor solid-state laser with automatic temperature stabilization.
Compared with conventional helium-neon gas lasers, the solid-state laser source avoids long warm-up times and relatively short operating lifetimes, improving overall usability and stability.
• Automatic Optical Alignment
LT2100 uses an automatic alignment system to help maintain the correct optical configuration and reduce manual adjustment requirements.
• No Lens Replacement or Standard Sample Calibration
The system covers its specified measurement range without requiring lens replacement. It also does not require calibration using standard reference samples for routine operation.

Working Principle
The LT2100 Series uses the laser diffraction/static light scattering principle for particle size analysis.
During measurement, a laser beam passes through the dispersed sample. Particles scatter the incident laser light at angles related to their particle size. Generally, larger particles produce stronger scattering at smaller angles, while smaller particles generate relatively larger-angle scattering.
The optical detection array collects scattered light over a broad angular range. The instrument then applies an appropriate optical model, including Mie or Fraunhofer theory, together with its optimized inversion algorithm to calculate the particle size distribution.
The LT2100 optical system incorporates polarization filtering, ACAD compensation, inverse Fourier optics, and large-angle detection technologies to improve the quality of the scattering signal and the reliability of particle size calculations.
