LAWRENCE, Mass., Nov. 19, 2012 — A line of lab spectrometers, the LF-Series from Spectral Evolution, offers a range of NIR spectrometer capabilities for general spectroscopy, water and moisture analysis, process monitoring, petrochemical analysis and refining studies, environmental studies, food and grain analysis, and polymer characterization and analysis. The spectrometers use an all-photodiode-array optical system directly mated to fiber optics to deliver maximum throughput; reliability, with no moving parts; autoexposure, autoscaling and auto dark shutter for fast, accurate one-touch scans; a stable, thermoelectrically cooled InGaAs array; USB and wireless Bluetooth communications; a choice of entrance optics, including fiber, lens, integrating sphere and right-angle diffuser; a standard bench package with SMA-905 input; DARWin data acquisition software; and optional battery operation with two rechargeable Li-ion battery packs. The software automatically saves data as an ASCII file to third-party software, with no extra export function necessary; collects reference or target data with a single click; compares current scans against libraries; and displays reflectance/transmittance data (percentage) or absorbance (logarithmic) versus wavelength. Single and multiple spectral plots are available. Models include the LF-2500 with a spectral range from 1000 to 2500 nm; the LF-2300 with an 1850- to 2500-nm spectral range; the LF-2100 with 1100 to 2500 nm; and the LF-1250 with 900 to 1700 nm.
