1）Fourier and Reverse Fourier Optical System

The Bettersizer 2600 is superior in the combination of Fourier and inverse Fourier designs. This smart design allows, on the one hand, the detection of scattered light in a very wide angular range from 0.016° to 165°. On the other hand, in contrast to the inverse Fourier design, the particles do not have to lie on one plane – the simultaneously accurate measurement of small and large particles is therefore achieved.

Features of the combination of Fourier and inverse Fourier design 

• Spherical detector array: Forward, lateral and backward detectors in 92 pieces in total; 
• Super large Fourier lens; 
• Small footprint: Compact design to save space.

2）Intuitive and Powerful Software

• Intuitive user interface and orderly operation
• Real-time PSD curve for determining the optimal measurement conditions 
• Fully automatic measurement routine 
• Automatic cleaning routine 
• Automatic data backup and highly customizable reports 
• Direct conversion according to Fraunhofer and Mie evaluation models 
• Switch between wet and dry dispersion modules with one click
