The Spectrelle®
spectrograph
 In cooperation between Systematix AB in Sweden and
GWU Laserteknik
GmbH in Germany, a new echelle spectrograph with CCD
detection has been launched on the market.
The spectrograph called Spectrelle® is the first model in a
series of future application dedicated
Spectrelle models. The present model, Spectrelle 20000, 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 Spectrelle
20000 has the
following main features:
|
Focal
length: |
110
mm |
|
F-number: |
3.6 |
|
Spectral range: |
365 -
705 nm (simultaneous) |
|
Spectral resolution: |
20000
FWHM with 3 channels/FWHM |
|
Number of spectral channels: |
47000 |
|
Detector: |
ALTA
47+ Broadband (1024 x 1024 pixels) |
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.
The control software, developed in C# for the .NET platform
under Windows XP is integrated with the
Peax™
spectral viewer and analysis software which includes a database
for displaying searching and identifying elements and molecules in a spectrum.
A LabVIEW SDK (software development kit) for operating the
spectrograph is also available.
