MultiSpec® UV-NIR: UV-NIR Detector Array Spectrometer Systems

MultiSpec UV-  NIR is part of the modular MultiSpec
instrument family of fast simultaneous readout spectrometer systems. Based on flexible
19“ chassis technology, it is the perfect tool for
process applications. The integrated spectrometers are high-sensitive modules without moving

parts and with outstanding long-term stability. The
detector array design allows acquisition of whole
spectra in milliseconds. Multiplexing technology
offers multichannel operation. The standardized
SMA connectors on the front allow easy coupling
of fiber optics with all types of probes and cells.

Multiplexing – Multi Channel Systems
The electronic spectral sensor multiplexer MUX-8A (for
Si-PDAs) provides important advantages. For multi-point
applications, spectra of up to 8 channels can be taken
simultaneously therefore, the costs per measurement point
is reduced dramatically. Variations and drifts of the light
source are compensated perfectly by using 1 channel as
reference channel. The tec5 multiplexer has no moving
parts and is fast and reliable.
For NIR applications an optical multiplexer based on piezo
technology is available. Fast switching time, low coupling
looses, very good reproducibility and a high lifetime are

Plug-In Cassette Design
MultiSpec systems follow a modular concept. All the components, such as spectrometers or light sources, are integrated into cassettes, which can be changed easily.
