Mechanical design of SPECORD
®
The major subassemblies of the SPECORD
®
are:
Light sources
Halogen lamp and deuterium lamp generate the light that is
monochromatized in the spectrometer system. Then, it passes
through the sample.
Premonochromator
(only on SPECORD
®
250)
The premonochromator is a holographic grating that rotates
synchronously with the monochromator grating. The thus
obtained predispersion of light reduces stray light.
Spectrometer system
The spectrometer system is protected against extraneous light
and dust by cover. The desiccator regulates the humidity
inside the system.
