High quality optical components ensure reliable
analytical data with low stray light achieved using
very low noise electronic circuits.
Deuterium and tungsten light sources deliver superior
stability across the full wavelength range. Both types
of lamp have self timers and are inexpensive and easy
to replace when required.
The monochromator is completely sealed and the
optical surfaces can be easily cleaned to maintain
optimum reflectivity over the lifetime of the instrument.
A maintenance free high resolution direct stepper
drive positions the grating precisely, which ensures
reproducible wavelength scanning at different scan
speeds, thus negating any wavelength peak shift.
The spectrophotometer shell is made from an
environmentally friendly non corrosive material and a
simple retaining mechanism on the base allows easy
access for air filter changes and routine maintenance.
