Spectrometer LTB Demon
High spectral resolution Double Echelle Monochromator series in Littrow configuration for the measurement of emission and absorption lines from the UV up to the NIR range.
- High absolute wavelength accuracy
- High spectral resolution (75,000-200,000)
- High optical throughput
- Suitable with various detectors (CCD, ICCD)
- Motorized optomechanics
By applying reflection optics with broadband UV layers and a CaF2 prism, chromatic aberrations are avoided and thus a large wavelength range from the UV to the NIR is provided. The light coupling into the DEMON spectrometer is realized via SMA fiber or reflection transfer optics. Various CCD and ICCD cameras are suitable for the designed detection area.
The supplied operating software Sophi with optional LabVIEW library for complete remote control of the DEMON allows fully access of all spectrometer-detector functions via graphic user interface and provides automated measurement routines with an integrated scripting language. All measured spectra are automatically plotted for comprehensive analysis that can easily be performed with Sophi.
