MultiSpec® NIR: NIR Detector Array Spectrometer System

MultiSpec 
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.

Features
❚t (Extended) InGaAs technology
❚t Available spectral range: 960 – 2170 nm
❚t Fast, precise, robust
❚t Longlife halogen light source (>12,000 h)

❚t Standard fiber-optic connection
❚t Multi-component analysis
❚t Up to 8 measurement channels
❚t High reproducibility and long-term stability

MultiSpec NIR
Light Source
The MultiSpec NIR systems is equipped with a highly stable
longlife halogen lamp. The light source is software controlled
and holds a shutter for automatic dark current correction.
tec5 uses only pre-aligned lamps for easy replacement.
Multiplexer
The optional multiplexer module MUX-FSM is based on
piezo technology and allows measurements of up to 8 channels. Fast switching time, low intensity reduction, a very
good reproducibility and a high lifetime are characteristic of
this module.
Alternatively, we offer a 2-channel optical multiplexer, which
