Polychromix DTS™ NIR Spectrometers
|
Now available from Ocean Optics is the Polychromix DTS™ NIR Spectrometer family. DTS Spectrometers are compact, low-cost NIR systems that are powered by Polychromix's MEMS architecture. Available in 0.9-1.7 µm, 1.7-2.5 µm and 1.1-1.3 µm wavelength ranges, the spectrometers have no moving parts, and feature a single-element InGaAs detector. The fully programmable spectrometers can be configured to operate in various scanning modes for a variety of general-purpose NIR applications that include quality control, education, R&D and industrial process control. |

Digital Transform Spectroscopy (DTS)
Polychromix's DTS Spectrometers use a grating and an innovative MEMS spatial light modulator to disperse light onto the the system's single-element InGaAs detector. Each wavelength of light can be modulated on and off with differing time sequences. The resulting time-varying signal is processed to create a spectrum. The DTS technology automatically corrects for stray light.
Spectrometer Models and Accessories
Ocean Optics offers three Polychromix DTS NIR Spectrometer models that vary by wavelength range. Each DTS Spectrometer includes a protective cover, DTS software, a USB cable and documentation.
Polychromix Spectrometers are covered by a 1-year warranty. An extended 5-year warranty is available for Call for Price. The extended warranty includes a yearly calibration service and a one-time exchange for an equivalently priced Polychromix device.
Software
Polychromix DTS NIR Spectrometers include the following software packages:
-
"My Instrument," compatible with GRAMS and select commercial software packages
-
"Polychromix SpectralCode™" spectrometer interface software
