Omni-λ500 Monochromator

The Omni-λ 500 is a superior spectral resolution monochromator for more demanding spectroscopic applications in a 500 mm focal length package and high speed f/6.5 aperture for excellent light gathering capability.

Like the other members of the Omni-λ family, it utilises a single piece cast construction and an interchangeable triple grating turret on a precision kinematic mount that provides unparalleled repeatability and reproducibility in spectral position. Up to three turrets can be supplied per system and recognised by the microprocessor controller.

The system is controlled through a USB 2.0 interface making it easy to integrate to your experiment control system either using our spectroscopy software or through an Active X control for integration into your own software.

Versatile entrance and exit port configurations and a large field area on the array output makes the spectrograph ideal for multichannel detector use. This is an excellent analysing system for applications where enhances spectral resolution combined with very low stray light levels are important such as Raman, atomic emission, laser fluorescence and high resolution absorption/transmission measurements.
