(MINI
VIS SPECTROMETER WITH LIGHT SOURCE)
Miniature VIS Spectrometer with Internal Light Source - SPECTRA
2000
 SPECTRA 2000 (download datasheet (134kB)) is a fiber coupled VIS
spectrometer with an internal light source. It is characterized by an excellent
straylight performance, a high sensitivity and small dimensions.
SPECTRA 2000 is offered in two versions:
The RS232
version supplied with a PC cable and a power supply. The instrument
automatically detects the COM port. Thus problems during installation are
avoided.
The USB version (under development) can easily be connected with an
USB
port of the PC and the measurement can be started immediately - a real plug
and play solution. The device is bus powered.
The software ATX SPECTRA is
suited for spectra acquisition and transmission/ reflection calculations. Single
and continuous measurement modes as well as averaging are possible.
Data can
be exported to Excel spread sheets and to ASCII files.

|
The device can be delivered with
various
fiberoptic measuring heads,e.g. dip and reflection probes.
