Omni-λ750 Monochromator

The Omni-λ750 monochromator is a 750 mm focal length instrument that is designed to provide a dispersion of 1.1 using a 1200g/mm grating across the large flat field exit port. The system features the Omni- triple grating turret on its precision kinematic mount that allows easy interchangeability and automatic realignment of the turret

Each turret can accommodate up to three gratings. The USB 2.0 interface to the microprocessor controller allows easy connection to your experiment control system or user programming using the Active X control. Thanks to the microprocessor controller, up to 9 grating conditions, linearisation functions and spectral calibrations can be stored providing a highly versatile research instrument for a wide variety of spectroscopy applications.

With a 1200 g/mm grating the spectral resolution of the Omni-λ 750 is better than 0.03 mm making it an ideal monochromator for high resolution spectroscopy, especially since it also features a high aperture of f / 9.7 and excellent light gathering capability. This is an excellent system for demanding measurements, for examples; photoluminescence, laser fluorescence and atomic emission.
