Laser Diffraction System
1. Patented Technologies Driving Instrument Excellence
1.1 Combination of Fourier and Inverse Fourier Design
The Bettersizer 2600 is superior in the combination of Fourier and inverse Fourier design. Its laser system structure features 92 detectors in total, including forward, lateral, and backward detectors. Equipped with a widely distributed spherical detector array, the Bettersizer 2600 can detect light signals across a broad angular range from 0.016° to 165°, enabling precise measurement of both small and large particles.
Total internal reflection occurs when the light transitions from a denser medium (glass) to a rarer one (air) and the incidence angle exceeds the critical angle, limiting the angles at which light can escape. The Bettersizer 2600’s innovative sample cell, with its tilted design, effectively minimizes total internal reflection. This allows more light signals to reach the detectors, enhancing measurement reliability and ensuring the acquisition of more comprehensive sample information.
1.2 Refraction Index Measurement
Under Mie theory, measurements by laser diffraction can be particularly challenging for samples due to a variety of factors, including the following:
- Samples with completely unknown complex refractive index;
- Samples with heterogeneous chemical composition;
- Samples with significantly different particulate optical properties compared to the bulk material;
- Samples having a distinctly strong optical dispersion (small Abbe number).
To address these challenges, determining the refractive index is one of the most effective solutions. The Bettersizer 2600 offers the following capabilities:
- Determine refractive index for samples with unknown refractive index;
- Measure samples with unknown properties;
- Verify the known data of a material at a specific light wavelength;
- Provide key parameters to calculate particle size distribution in real-time
