Omni-lambda 500

Triple Grating Spectrograph

The Omni-lambda 500 is a monochromator / spectrograph for use in applications where superior spectral resolution is required e.g. Raman, atomic emission and high resolution absorption / transmission measurements.  The package length is 500 mm with a high speed f/6.5 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.
