Modular concept
The Cary 3500 UV-Vis introduces a modular concept to the Agilent Cary range of
high performance spectrophotometers. Modularity splits instrument function
between light generation and light measurement. The Cary 3500 UV-Vis engine
produces monochromatic light which is measured by the various Cary 3500 UV-Vis
sample measurement modules. This allows for the tailored development of specific
modules for applications while maximizing the flexibility of the system.
The Cary engine is based around Xenon flash lamp technology coupled with a
compact dual out of plane monochromator. As with any spectrophotometer
photometric performance is largely determined by the quality of the
monochromator. With UV-Vis instruments, the monochromator design is aimed at
providing a desired wavelength resolution while maintaining high light throughput
and low stray light.
Modules
Cary 3500 UV-Vis modules couple with the engine to provide measurement
functionality for target applications. The Multicell and Compact UV-Vis modules
provide measurement solutions for cuvette-based applications.
