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.
|Diffraction gratings, grooves/mm||2400||1800||1200||600||400||300|
|-possible spectral range of grating operation, nm||200-550||200-710||200-1000||200-1000||200-1000||200-1000|
|-multichannel array bandpass (average), nm||100||125||230||490||700||1000|
|-reciprocal linear dispersion (average), nm/mm||3,8||5,25||8,0||18,0||24,0||35,0|
|-spectral resolution (average), nm*||0,15||0,2||0,3||0,6||0,8||1,2|
EXAMPLE: If you are interested in the 1800 gr/mm grating (spectral resolution 0.2 nm), you then have to choose a location of the multichannel array bandpass 125 nm within the possible spectral range of grating 200-710 nm.
Upon Your request, the S100 spectrometer can be equipped with high-order separating compound filter designed for operation with broadband spectra.
The S100 spectrometer can be supplied with VUV or FWF optical fibers with various lengths.
The S100 spectrometer has a wide range of options and accessories that allow efficient collection of light from the sample located at a finite distance and in infinity:
Condenser PS-2 is designed for collecting light from a sample located at 40 mm distance within a wide spectral range and its effective transmission into an optical fiber or onto an entrance slit of a spectral device.
Condenser PS-3 is designed for collecting light from a sample located at 29 mm distance within a wide aperture angle and its further transmission into an optical fiber or onto an entrance slit of a spectral device.
Adapter FA-1 – achromatic adapter for focusing parallel beam to a fiber with 3D-alignment.
Adapter FA-2 – achromatic adapter for focusing parallel beam to a fiber with an axial alignment.
Cassegrain objectives allow collecting light from objects located at a distance of 3.5m to infinity.
Diffuse attenuator FA-3 is designed to attenuate the laser beam while delivering it to a fiber.
Contact a SOLAR LS specialist to select the complete set of the device that meets the requirement of your instrument complex in the best way.
