|Miniature spectrometer getSpec 2048 x 14 for UV, VIS and NIR range|
| Request for information|
The getSpec-2048x14 Fiber Optic Spectrometers is a back-thinned type CCD spectrometer with high quantum efficiency and high UV sensitivity. The optical design is based on the getBench-75 symmetrical Czerny-Turner design with a 2048x14 pixels high UV sensitive CCD image sensor. The image sensor is used as a linear array of 2048 pixels binning the vertical 14 pixels to optimize efficiency. The spectrometer has a fiber optic entrance connector (standard SMA, others possible), collimating and focusing mirror and a diffractional grating. A choice of 16 different gratings with different dispersion and blaze angles enable applications in the 200-1160nm range. The getSpec-2048x14 comes with a 16 bit AD converter, and USB2.0 high speed interface.
The getSpec-2048x14 is especially suitable for measuring low light, fluorescence and UV- applications. Digital IO ports enable external triggering and control of shutter and pulsed light sources from the getSpec product range.
The new getSpec-2048x14 has a USB2 interface with fast data sampling of 450 spectra per second and data transfer in 2.24 msec and supports analog in-and outputs as well. Optional BluetoothÒ (-BT) communication and an SD card for on-board saving of spectra can be added. The getSpec-2048x14-USB2 runs on USB power and comes with getSoft basic, a complete manual and USB interface cable. Multiple (up to 127) USB2 spectrometers with different detector types can be externally coupled.
