AvaSpec-2048 Fiber Optic Spectrometer
AvaSpec-2048
The AvaSpec-2048 Fiber Optic Spectrometer is
based on the AvaBench-75 symmetrical Czerny-
Turner design with 2048 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-2048 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-2048 is especially suitable for low light
level and high resolution applications. An optional detector coating enhances 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 AvaSpec-2048 is also available as dual channel or multiple channel instrument (up to 8
channels), where all spectra are taken simultaneously.
The AvaSpec-2048 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-2048-SPU has a switch to run on USB power or external power.
The new AvaSpec2048-USB2 has a USB2 interface with ultrafast datasampling of 500 spectra per
second and datatransfer in 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-
2048-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.
