Omni-lambda 300

Triple Grating Spectrograph

The Omni-lambda 300 is a monochromator / spectrograph for use in applications where medium to high spectral resolution is required e.g. fluorescence, Raman, absorption / tranmission measurements and source characterisation.  The package length is 300 mm with a fast f/3.9 aperture for increased light gathering capability.  Gratings are held on a interchageable triple sided turret, mounted on to a precision kinematic mount offering unparralled repeatability and reproducibility in spectral position, with up three turrets being supplied with each system.  Various configurations are available as shown below.  System control is via USB 2.0 and the supplied software, or ActiveX for integration into your own software.
