SC82 MINIATURE SPECTROMETER
FEATURES
The new compact spectrometer SC82-S13496 utilizes high sensitivity CMOS linear image sensors S13496 and S11639. Highly sensitive (photosensitivity up to 650 V/lx*s), the S13496 image sensor allows using the SC82 spectrometer for low light applications such as Raman scattering, fluorescence, multi-channel spectrophotometry etc. The embedded IMAGING capability features an astigmatism compensator thus further enhancing system sensitivity. Standard Toshiba CCD image sensors TCD1304 and TCD1205 are also available

1) signal level reaches 50% of dynamic range.
2) antiblooming – sensor’s feature eliminating overflow of charges from over-exposed pixels to the neighboring ones.
3) max exposure time is the time at which dark signal makes up 25% of the dynamic range at +25°C ambient temperature
At the time of placing your order you should choose a grating grooves density (i.e. spectral resolution of your instrument), as well as the spectral range for operation. For your convenience, the table below lists the average values of grating dispersion, spectral resolution and multichannel array bandpass. Contact a SolarLS specialist for more precise calculation of parameters for your instrument.
