Laser fitted
The Zetasizer Nano series is available with either a 633nm ‘red’ laser or a 532nm
‘green’ laser fitted. The laser fitted is identified by the colour of the oval badge on
the cover.
.
The 633nm laser is least suitable for blue samples.
.
The 532nm laser is least suitable for red samples.
90° optics
The instruments above with the suffix 90 indicate the optics have a 90° scattering
angle. These models have been included in the Zetasizer Nano instrument range
to provide continuity with other instruments with ‘classical’ 90° optics.
Instrument options
A range of accessories and options are also available for more advanced
measurement strategies.

Narrow band filter
This filter improves the signal for samples that fluoresce at the wavelength
of the laser fitted. If fitted an option label will be attached to the front of the
cuvette holder.
