AvaSpec Multichannel Fiber Optic Spectrometers
AvaSpec-4 channel in desktop
AvaSpec –USB1 platform
The AvaSpec USB1.1 platform Fiber Optic
Spectrometers can be configured as single,
dual, triple, quadruple or multi-channel
instrument with up to 8 different
spectrometer channels, all read out
simultaneously, controlled by a master´s
board microprocessor.
The simultaneous data-sampling allows fast
read-out and enables monitoring of pulsed
light sources with different channels looking
at the same pulse.
Multi-channel spectrometers all consist of the
same detector type (102/128, 256 or 1024 or 2048 pixels), the spectrometer channels can of course
cover different wavelength ranges or have different resolution specifications. For each channel
grating, wavelength range and options need to be specified.
The multi-channel spectrometers all run with one USB interface and under AvaSoft software.
Multi-channel housing can be in 9.5” desktop (for 1-4 channels) or 19” rack mount housing (1-8
channels) The pinout of the backplane connector can be found in section 2.8.1.
AvaSpec –USB2.0 platform – maximum modularity
The new AvaSpec-USB2.0 platform offers maximum modularity for multi-channel applications. For
each channel a different wavelength range, detector and integration time can be selected, without
loosing the advantage of synchronization between the different channels. The AvaSpec-USB2.0
platform uses the USB2.0 bus to connect the different channels to the PC platform and supports up
to 127 channels. New applications that can be realized with the AvaSpec-USB2.0 multi-channel
platform:
Different integration times or averaging setting per channel, still start each scan
simultaneously for all synchronized channels
Different detector types, such as UV/VIS and NIR detectors possible to cover a wide
wavelength range with one spectrometer system
More than 8 channels (even up to 127 channels) can be connected through USB2 hubs.
To order a USB2.0 multi-channel, please specify the different spectrometers (-RM) and options and
the housing (up to 4 channels in desktop, up to 10 channels in rack mount).
The spectrometer units are internally connected by a synchronization cable, which allows
simultaneous data-sampling. The synchronization enables monitoring of pulsed lightsources with
different channels looking at the same pulse.
The pinout of the backplane connector can be found in 2.9.2
