The AvaSpec-3648 Fibre Optic Spectrometer is based on the AvaBench-75 symmetrical Czerny-Turner design with 3648 pixel CCD Detector Array. The spectrometer has a fibre optic entrance connector (as standard SMA - other types are 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-3648 is delivered with a high speed USB2 interface and 14bit A/D converter.

The AvaSpec-3648 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 a shutter and pulsed light sources from the Avantes line of instruments.

The AvaSpec-3648 is also available as a multiple channel instrument (up to 8 channels), where all spectra are taken simultaneously.

The AvaSpec-3648 is supplied as standard with AvaSoft-BASIC, a complete manual, USB interface cable and will run on USB power (-SPU option). However, a PS-12V/1.0A power supply can be ordered separately for mains power use if this is preferred. In this case, the user will then have both options available. AvaSoft-FULL and application specific software can be ordered separately from the AvaSoft software library.

The AvaSpec-3648 has a USB2 interface with ultrafast datasampling of 270 spectra per second, data transfer in 3.7msec and supports analog inputs and outputs.

Optional Bluetooth® (-BT) communication and an SDRAM card for on-board saving of spectra can be added.

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').
