DLS

Dynamic light scattering

Modes

Static (SLS) | Dynamic light scattering (DLS) | depolarized DLS | 3D cross-correlation scattering (3D-DLS) for optically turbid  samples.

Laser

Cobolt 05-01 diode pumped solid state laser
λ = 660 nm | P max. = 500 mW | linearly polarized and collimated

Light collection

• Single-mode optical fibres  with integrated collimation optics and laser-line filters
• Scattering angles: 10° to 135°
• Q-range for aqueous suspensions: 2.2 10⁶  to 2.3 10⁶ m^-1
• Two high-sensitivity APD detectors  (Perkin Elmer, Single Photon Counting Module)
• Single processing via a two-channel multiple-tau correlator
