A Guided Tour of the Spectrum Two N
PerkinElmer Spectrum Two N spectrometers are compact, robust instruments that can be
used in non-laboratory environments.

• Spectrum Two N FT-NIR spectrometers with standard detector:
– Standard, high-performance, room-temperature LiTaO
3
(lithium tantalate) NIR
detector.
– Optical system with CaF
2
windows enables you to collect data over a total range
of 14,700 to 2,000 cm
−1
at a best resolution of 1.0 cm

.
– Standard APV/AVI configuration.
For APV, an internal, software-controlled filter wheel comes complete with traceable
reference materials for automatic performance verification. Also, the methane cell
provided enables the production of standard data to be referenced to fundamental
band positions using the Absolute Virtual Instrument (AVI) feature.
• Spectrum Two FT-IR spectrometers with temperature-stabilized detector:
– Temperature-stabilized, high-performance, InGaAs (indium gallium arsenide) NIR
detector for enhanced signal-to-noise.
– Optical system enables you to collect data over a total range of 14,700 to
3,800 cm

The instrument is connected to a PC, either point-to-point (USB 2.0 or Ethernet), over a
network, or via a wireless network using the optional wireless router.
The Spectrum software supplied enables you to control the instrument and to manipulate the
spectra that you collect. The spectrometers can operate in ratio, single-beam, or
interferogram mode.
