Each sCAL device
is individually numbered to allow spectra to be linked directly to
each calibration chip. The silicon is mounted on standard 3"
glass microscope slide for easy handling and maximum ease of use with
Raman systems.
As silicon is a single crystal, the calibration spectra are also identical
irrespective of the magnification under which the Raman spectra are
recorded, making sCAL highly suited for calibrating micro Raman systems.
Silicon is also a very strong Raman scatterer, which means that calibration
spectra can be recorded quickly and easily, speeding the verification
process.
Using similar production processes to Mesophotonics Klarite SERS substrates,
sCAL substrates offer a quick and easy to use calibration standard.
Multiple sCAL slides can can be supplied from the same original single
crystalline piece of pure silicon. These can then be used for calibrating
multiple instruments in multiple sites, offering the reassurance that
they are all calibrated to the same original source material.
