An automated computer-controlled tri-grating mount is standard. Up to three gratings can be placed on the mount for continuous scanning over extended wavelength ranges. Additional user interchangeable tri-grating turrets are available for covering extremely wide wavelength ranges when more than three gratings are required. An automated computer-controlled, 11-position second order blocking filter wheel is also standard. The wheel has sufficient filter positions to cover the entire 0.2 mm to 30 mm wavelength region and also provides shutter and open positions.
