​• Wavelength range: 200-1050 nm
​• Fast acquisition: 2857 spectra/sec (full spectra)
​• Back thinned 2048 CCD array detector
​• 500 grooves/mm grating blazed at 300 nm
​• Enhanced sensitivity option
​• LightScan+ software included

The SPEC SPEED+ UV/Vis/NIR is a wide range, high speed spectrometer that uses a back thinned CCD linear array from Hamamatsu allowing up to 2857 spectra per second. The full configuration includes a 25 µm slit, 500 grooves/mm grating blazed at 300 nm, order sorting filters and SMA 905 optical fiber connector.

This standard configuration has great specifications either for its wide wavelength range (200-1050 nm) and resolution (1.7 nm), for its speed and for the possibility to control additional parameters with LightScan+ software.

Ther spectra below show the full range obtained with a Mercury Argon light source. Even with a wide range configuration, the separation between doublet 576.960 and 579.066 is achieved.
