仪器简介：
The compact spectrometer system DEMON consists of a high-resolution CCD Echelle spectrometer in sequence with a prism monochromator which is used for the selection of the inspection range. For this purpose the width of the prism monochromator exit slit, which serves also as entrance slit of the Echelle spectrometer, is adjustable. The prism and the Echelle grating are both arranged in a Littrow mounting and use the high imaging quality of parabolic mirror optics.
技术参数：
Specifications DEMON Series
Optical design: Echelle spectrometer with pre-monochromator and
active wavelength stabilization
Wavelength range: 190 nm - 900 nm ( 190 nm - 150 nm on request)
Linear dispersion*: λ/225,000
Resolution(3 pixels): 2.7 pm @ 200 nm; 8.9 pm @ 670 nm
Absolute accuracy: λ/1,000,000
Dynamic : 16 bit
Detector: CCD line-array detector 1,024 Pixel or ICCD
Input aperture: F/10
Exposure Time: 1 ms - 10 s with CCD; 5 ns - 1s with ICCD
Light coupling: UV fiber down to 240 nm or mirror optics down to 190 nm
Control: control of motors and calibration lamp via PC
Dimensions: 600 x 200 x 300 mm3 , 15 kg
Software: Sophi; LabView driver optional
Integrated mechanical shutter and a motorized slit
主要特点：
Advantages of this concept compared to Echelle spectrographs with internal order separation which generate a two-dimensional spectrum are the extremely high spectral resolution, the high optical throughput obtained by exploiting the full height of the slit and the short read-out time of the detector due to “on-chip-binning”. Further advantages of the system are the low stray light level resulting from the double monochromator arrangement and active wavelength stabilization using internal calibration lamps. Thus, highest absolute wavelength accuracy can be achieved without extensive temperature stabilization. The system is compact and extremely thermally and mechanically stable. By applying reflection optics with broad-band UV coating and a CaF2-Prism chromatic aberrations are avoided and a large wavelength range from the deep UV up to the IR is provided . The spectrometer illumination is realized using SMA fiber coupling or mirror transfer optics.
The DEMON can in principle be coupled with all cameras using 1/2” or longer CCD or ICCD arrays.
The full motorization and an electro-mechanical shutter allow a very comfortable software-based operation. The spectrometer software Sophi provides for the complete control of the spectrometer as well as for the display and evaluation of the spectrum.
An optional LabView driver allows the remote control of the DEMON and thus the integration into complex test stands.
