Three different NIR systems provide you with multiple wavelength ranges for measuring sugar, alcohol, moisture, fats and more. These small-footprint, plug-and-play systems provide a full spectrum in one millisecond, and offer optical resolution as low as 3.0 nm FWHM. InGaAs Detector Cooled for Optimum Signal-to-Noise and Sensitivity The NIR-series Spectrometers each feature a Hamamatsu InGaAs linear-array detector with onboard thermoelectric cooling. A thermistor monitors the array's temperature and a thermoelectric device can cool each array to 30 °C below ambient, keeping the array stable to within ±0.1 °C. You can set and monitor the detector's temperature via software. NIR512 Spectrometer: 900-1700 nm The NIR-512 Spectrometer features a 512-element InGaAs linear-array detector. With the NIR-512, the only diffractive grating available is Grating N1, and it provides a 900-1700 nm wavelength range, producing an optical resolution of <5.0 nm FWHM. NIR256-2.1 Spectrometer: 1200-2100 nm or 900-2100 nm The NIR256-2.1 Spectrometer uses a 256-element InGaAs linear-array detector. With the NIR256 you have two grating options. With Grating N1, you have a 1200-2100 nm wavelength range. Grating N2 provides a 900-2100 nm wavelength range. NIR256-2.5 Spectrometer: 900-2500 nm The NIR256-2.5 Spectrometer extends farther into the NIR, acquiring real-time spectra up to 2.5 pm. With the NIR256-2.5, you select Grating N2, which provides a wavelength range of 900-2500 nm. Plug-and-Play USB Operation All of the NIR-series Spectrometers interface to PCs via USB 2.0. When operating the spectrometer via the USB port, you have access to the spectrometer's EEPROM, where wavelength calibration coefficients and other data unique to your spectrometer are stored. SpectraSuite Spectroscopy Operating Software reads these values for easy setup and swapping among PCs. A 1 6-bit A/D industrial converter is mounted with the spectrometer in the same housing. A 5 VDC wall transformer (included) is required. These systems also have a serial port for interfacing to PCs, Plcs and other devices that support the RS-232 protocol.
