High Resolution Spectrometer UV/VIS - getSpec 3648



Request for information



  • High resolution - 3648 pixel detector
  • USB 2.0 interface – 480 Mbps
  • Data transfer speed: 3.7 ms/Scan
  • Optional: Bluetooth-communication
  • Saving on internal SD RAM-card

The new getSpec-3648 spectrometers were developed for fiber optic spectroscopy applications in the UV/VIS and shortwave NIR range. These instruments are suited for laboratory, industrial, biotechnology, medical and environmental (mobile) use. The spectrometers are based on a revolutionary electronics design with a 14-bit multi-channel AD converter, on-board microprocessor and USB 2.0 high speed interface. The detector of the spectrometer is a 3648 pixel, high sensitive CCD SONY detector. The optical bench has 75 mm focal length and can be used for measurements from 200 – 1100 nm, with high spectral resolution of up to 0,025 nm FWHM. This spectrometer can be configured as a multi channel instrument, taking spectra from up to 8 channels simultaneously with a minimal integration time of 10 Ás. 14 (2 in, 12 out) programmable digital IO ports can be used for external triggering, control of external light sources, shutters or process applications.


The spectrometer has a fiber optic entrance connector (Standard SMA, others possible), collimating and focusing mirror and diffractional grating. A choice of 12 different gratings with different dispersion and blaze angles enable applications in the 200-1100nm range.
The new getSpec-3648 has an USB 2.0 interface with fast data sampling of 270 spectra per second and data transfer in 3.7 msec and supports analog in- and outputs as well. Optional Bluetooth (-BT) communication and an SDRAM card for on-board saving of spectra can be added. The getSpec-3648-USB 2.0 runs on USB power and comes with getSoft-basic, a complete manual and USB interface cable.
