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 15 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 with 14 bit AD converter; either with USB1.1 or the new USB2.0 interface. 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 is available as an option to run on USB power and does not need an additional power supply.
The new AvaSpec-2048-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 BluetoothŇ (-BT) communication and an SDRAM 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 (see section multi-channel spectrometers).
