Omni-λ300 Monochromator

The Omni-λ300 monochromator system is a versatile system with a precision direct drive and a triple grating turret that offers unparalleled repeatability and reproducibility in any spectral position for selecting a particular wavelength of light ranging from the UV range through to the NIR range from a continuous source.


The system is constructed using a single piece casting for superb structural rigidity and also features flexible input and output port options that allow it to be configured as either a monochromator or a spectrograph system with a two-dimensional array detector. Flexible grating options make this monochromator an ideal general purpose unit that can cover a wide range of application requirements for UV and IR and from medium to high spectral resolution depending upon grating choice with excellent optical throughput and low stray levels.

The Omni-λ300 features a fully interchangeable grating turret utilising a high repeatability kinematic mount. The microprocessor controller can accommodate up to three turrets each with different gratings, 9 gratings in total, for the ultimate in flexibility, and uses a USB 2.0 interface for easy connection.
