SC125  HIGH SENSITIVITY COMPACT SPECTROMETERHIGH SENSITIVITY COMPACT SPECTROMETER
SC125

The compact high-sensitivity spectrometer SC125 is developed
for low light applications such as measurements of Raman
scattering, fluorescence, etc., which require especially highsensitivity or enhanced specifications in the UV spectral range.

FEATURESAPPLICATIONS Up-to-date model based on back-thinned arrays for
operation with low signals

 Raman scattering, fluorescence measurements
 Application with high sensitivity requirement Enhanced UV sensitivity

 Analysis of any light source in the 190-1100 nm spectral range

 Monolithic housing for optimum stability
 Internal light traps to reduce stray light

The high-aperture optical bench of the SC125 has no moving partsand minimises the number of reflective surfaces. The SC125 featuresa monolithic housing, thus ensuring long-time measurement
stability. The housing has internal fins: light traps that allow reducing
stray light – a typical problem of compact short-focal length
instruments.

arrays have wide spectral range and excellent sensitivity in the UV(see below for the curves of each detector spectral sensitivity andtheir specifications). These two arrays differ in quantum efficiency,
data reading rate, dynamic range, and in pixel active area size.

The IMAGING Version (Optional) features an astigmatism
compensator – cylindrical lens – installed after the entrance slit. Thisfurther enhances of system sensitivity.

The detector based on the S7030-1006 CCD-array is more sensitive,
has lower noise, better dynamic range and uniformity. The detector
based on the S10420-1106 CCD array is faster, has anti-blooming
and, since it has a greater number of pixels and smaller pixel size,ensures better spectral resolution than the S7030-1006.

The SC125 may contain as a detector either one of two non-cooled
Hamamatsu back-thinned CCD-arrays without a charge-storage
section (back-thinned FFT CCD), operating in the binning mode. BothUpon your request, SC125 may be supplied with an order-sorting
filter installed. We recommend this option for operation withbroadband spectra.

2) Anti-blooming – sensor’s feature eliminating overflow of charges from over-exposed pixels to the neighboring ones.
3) Maximum storage time is deemed to be the time at which dark signal reaches 25% of the dynamic range at the ambient temperature +25°С.
4) As an option.

At the time of placing your order you should choose grating grooves density (i.e. spectral resolution of your instrument), as well as the spectral range for operation. For yourconvenience, the table below lists the average values of grating dispersion, spectral resolution and multichannel array bandpass (average).
