Enabling Handheld, Portable, and On-line Near-Infrared Applications
Infrared spectroscopy is a widely used technology for quantitative and qualitative analyses of solids, liquids, and gases in applications in food and agriculture, medical, pharmaceutical, and environmental sensing. The advent of miniaturization has been spurred by the need for on-site, non-destructive, point-of-use, and rapid analyses of samples in law-enforcement applications, homeland security, food safety, on-line process control, and counterfeit detection of pharmaceutical products to name a few.
Utilizing advanced thin-film coating design and manufacturing technology in linear variable filters (LVF), JDSU is introducing an ultra-compact, lightweight, cost-effective near-infrared (NIR) spectrometer that relies on an LVF as the dispersing element.
The LVF is a bandpass filter coating that has been intentionally wedged in one direction. Since the center wavelength of the bandpass is a function of the coating thickness, the wavelength transmitted through the filter will vary in a linear fashion in the direction of the wedge. The JDSU line of LVF spectral sensors uses an LVF coupled to a linear detector array to create a sensor capable of providing spectral information for a wide variety of commercial, industrial, and scientific applications.
The LVF detector, light source, collection optics, and electronics are fully integrated in a palm-size device. The MicroNIR™ Pro spectrometer is offered with model building and real-time prediction software capability for at-line, on-line, and field-use applications.
