AvaSpec-1024 Fiber Optic Spectrometer
AvaSpec-1024
The AvaSpec-1024 Fiber Optic Spectrometer is
based on the AvaBench-75 symmetrical Czerny-
Turner design with 1024 pixel CMOS 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-1024 can be delivered with 2
platforms of electronics; either with USB1.1 with
14 bit AD converter or the new USB2.0 interface
with 16 bit AD converter.
The AvaSpec-1024 is specially suitable for low
noise applications with good resolution. Digital IO ports enable external triggering and control of
shutter and pulsed light sources from the Avantes line of instruments.
The AvaSpec-1024 is also available as dual channel or multiple channel instrument (up to 8
channels), where all spectra are taken simultaneously.
The AvaSpec-1024 comes with AvaSoft-basic, a complete manual, USB interface cable and a PS-
12V/1.0A power supply. AvaSoft-full and application software can be ordered separately.
Alternatively the AvaSpec-1024-SPU has a switch to run on USB power or external power.
The new AvaSpec1024-USB2 has a USB2 interface with ultrafast datasampling of 450 spectra per
second and datatransfer in 2.2msec 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-1024-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
