Spectrelle® 20000

Spectrelle^® 20000 The Spectrelle® 20000 spectrograph

The Spectrelle 20000 model has been developed with focus on applications in fusion boundary plasma spectroscopy. It simultaneously records high resolution spectra at a frame rate of up to one Hertz depending on illumination conditions.

Through a special optical design the Spectrelle 20000 has a uniquely high throughput. Its F-number of 3.6 is better than any other commercial echelle spectrograph on the market.

The optics in the Spectrelle 20000, including entrance aperture and camera, is mounted on an INVAR framework, isolated from the outer housing. This gives the system a unique thermal stability.
