Optical Spectroscopy
The equipment available permits optical emission spectroscopy in
the UV, visible and near infrared ranges from 185 to 1100 nm. A
spectrometer with CCD camera permits to record the whole range in
one shot, while a classical spectrograph with cooled photo
multiplier has a resolution better than 0,2 nm and single photon
detection capability. An optional integral Fabry-Perrot
interferometer is used for line shape studies with pico-meter
resolution.
CCD-Spectrometer: OceanOptics
HR4000 with HC-1
grating time resolution of 10μs and spectral resolution of
0,5nm is achieved in the range of 185 to 1100 nm.
Our interferometer.
Spectrograph: 1 m focal length Cerny-Turner Spectrograph with a
spectral range of 185 to 900 nm and a resolution of 0,02 nm or
better. A cooled photo multiplier detects singe photons with a time
resolution better than 5 ns.
The Fabry-Perrot interferometer can be inserted into the
spectrograph for very high resolution studies.
Remark: The use of fiber optical cables restricts the lower wave
length limit to 230 nm.
