Three versions of the spectrometer are available:
•
DTS™-1700 which covers the 900 - 1700 nm region
•
DTS™-2500 which covers the 1700 - 2500 nm region
•
DTS™-NB which covers the 1100 - 1300 nm region
Operation of the three systems is identical, except for the wavelength range
that each spectrometer covers.
The spectrometer provides the user with a number of important benefits
including:
•
Rapid data acquisition - A spectrum can be acquired in 1 second.
•
A minimum power requirement - The spectrometer is driven by a standard
USB port of a personal computer.
•
Rugged design - There are no moving parts.
•
The performance is unaffected by stray light
•
The system is compact and lightweight.
The spectrometer is typically employed as a part of a system that includes a
source and a sample holder (a cuvette holder or a reflectance sphere) as
shown in Figure 1-2. As an example, the spectrometer can be used with the
Ocean Optics HL-2000 Tungsten Halogen Light Source and the Ocean
Optics CUV-UV Holder for 1-cm cuvettes or the Ocean Optics ISP-REF
Integrating Sphere. The source and cuvette holder or reflectance sphere are
acquired separately (e.g. Ocean Optics, Inc., Dunedin FL,
www.oceanoptics.com). As an alternative, the spectrometer can be directly
connected to the source to obtain the spectrum provided by the source).
