3D 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 10m-1
  • Two high-sensitivity APD detectors  (Perkin Elmer, Single Photon Counting Module)
  • Single processing via a two-channel multiple-tau correlator

  • Reservation via the booking platform is mandatory.
  • Reservations cannot be placed more than 2 weeks (14 days) in advance.
  • Cancellations must be announced at least 24 hours in advance, in order to give other users a chance to use the opened time slot.
  • Early finished: inform the user that is coming after you (email and phone in the booking)
  • Before starting the session, the user must check the instrument and report any damage or incorrect state immediately to the Responsible.
