SPEC SENSE+ / SPEC SENSE+ UV/Vis/NIR
• Wavelength range: 200-1050 nm
• Wide range and high sensitivity in one unit
• Back thinned 2048 CCD array detector
• 500 grooves/mm grating blazed at 300 nm
• 1 mm pixel height for a large detection area
• LightScan software included
The SPEC SENSE+ UV/Vis/NIR is a wide range, high sensitivity spectrometer that uses a back thinned CCD linear array from Hamamatsu with 1mm height pixels for the best sensitivity. This configuration uses a 500 grooves/mm grating blazed at 300 nm, a 200 µm slit allowing a significative amount of light collection, collecting lens, order sorting filters and SMA 905 optical fiber connector.
This configuration allows light collection from low light emitting sources in Irradiance measurements being also a good choice for Fluorescence, Phosphorecence and Chemiluminescence determination.
With minimum integration time of 1ms allows up to 1000 spectra per second making it possible to follow with high sensitivity fast events such as Kinetics measurements in Chemistry and Biology R&D.The high dinamic range also allows determination of Absorbance on high optical density samples.
Due to its flexibility and sensitivity can be used in a wide range of applications: the example below shows the spectra with the variation of the gas mixture with time in spectroscopy of flames.
In this case, the kinetics module from LightScan software was used to obtain spectra at 0, 20, 40 and 60 seconds.
