Omni-lambda 150

Dual Grating Spectrograph

The Omni-lambd 150 is a monochromator / spectrograph for use in applications where high spectral resolution is not required i.e. illuminators, light filtration, low resolution spectral analysis, etc.  The package length is 150 mm with a fast f/4.2 aperture for increased light gathering capability.  Gratings are held on a double sided turret, mounted on to a precision kinematic mount offering unparralled repeatability and reproducibility in spectral position.  Output is either through an exit slit or directed to either a linear or area CCD detector.  System control is via USB 2.0 and the supplied software, or ActiveX for integration into your own software.
