AvaSpec-3648 Fiber Optic Spectrometer
The AvaSpec-3648 Fiber Optic Spectrometers is based
on the AvaBench-75 symmetrical Czerny-Turner design
with 3648 pixel CCD Detector Array. The spectrometer
has a fiber optic entrance connector (standard SMA,
others possible), collimating and focusing mirror and
diffractional grating. A choice of 16 different gratings
with different dispersion and blaze angles enable
applications in the 200-1100nm range. The AvaSpec-
3648 comes with a 16 bit AD converter, and USB2.0 high
speed interface. The AvaSpec- 3648 is especially
suitable for measuring high speed and high resolution applications, such as LIBS and pulsed light
sources. An optional detector coating can enhance the CCD performance for the UV range and a
detector collection lens offers high sensitivity.
Digital IO ports enable external triggering and control of shutter and pulsed light sources from the
Avantes line of instruments.
The new AvaSpec-3648 has a USB2 interface with fast data sampling of 270 spectra per second and
data transfer in 3.7 msec and supports analog in-and outputs as well. Optional Bluetooth (-BT)
communication and an SD card for on-board saving of spectra can be added. The AvaSpec-3648-USB2
runs on USB power and comes with AvaSoft-basic, a complete manual and USB interface cable.
Multiple (up to 127) USB2 spectrometers with different detector types can be
externally coupled.
