AvaSpec-128
The AvaSpec-128 Fibre Optic Spectrometer is the replacement of the AvaSpec-102 and based on the AvaBench-45 symmetrical Czerny-Turner design with 128 pixel Photo Diode Array. The spectrometer has a fibre optic entrance connector (as standard SMA - others types are possible), collimating and focusing mirror and diffractional grating. A choice of 11 different gratings with different dispersion and blaze angles enable applications in the 360-1100nm range. The AvaSpec-128 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-128 is especially suitable for low cost colour measurements.
Digital IO ports enable external triggering and control of shutter and pulsed light sources from the Avantes line of instruments.
The AvaSpec-128 is also available as dual channel or multiple channel instrument (up to 8 channels), where all spectra are taken simultaneously.
The AvaSpec-128 is supplied as standard 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-128-SPU has a switch to run on USB power or external power.
The new AvaSpec128-USB2 has a USB2 interface with ultrafast datasampling of 8000 spectra per second (with on board averaging) and datatransfer in 1.1msec and supports both analog in-and outputs.
Optional Bluetooth ® (-BT) communication and an SD card for on-board saving of spectra can be added.
The AvaSpec-128-USB2 runs on USB power and comes with AvaSoft-BASIC, a complete manual and USB interface cable.
For USB2 platform devices, multiple (up to 127) spectrometers with different detector types can be externally coupled (for further information, please view the section 'Multichannel Spectrometers').
