The MicroNIR Spectrometer from JDSU enables handheld and in-process microanalysis in one small package with 950-1650 nm or 1150-2150 wavelength ranges (depending on model; available in transmission) with custom ranges available. This USB-powered near infrared spectrometer utilizes linear variable filter (LVF) technology. The NIR spectrometer is placed on the sample and it generates a spectrum in seconds without the need for any moving parts. The MicroNIR Spectrometer provides near infrared spectroscopy for applications in pharmaceutical, food and beverage, forensics, agriculture, and materials analysis.
Hi. I'm Nada O'Brien, Product Line Manager of Infrared Products at JDSU.
I would like to show you our new breakthrough MicroNIR Spectrometer product, which is what I'm holding in my hand right now.
This is an ultra compact lightweight, NIR infrared spectrometer.
It weighs less than 60 grams or two ounces. It is the smallest NIR infrared spectrometer available in the market today.
What you're seeing in this little package is the entire spectrometer. It contains the light source, the collection optics, the dispersing element, the linear detector array, and the read-out electronics, all in one package like this.
It is fully powered through a mini-USB cable through a laptop or a tablet computer.
It covers the range of 950 to 1,650 nanometers in one version and 1,150 to 2,150 nanometers in another.
The technology behind achieving this level of miniaturization is based on JDSU's linear-variable filter technology.
Linear-variable filter is an inorganic bandpass filter that has a continuous wedge across the length of it so that the center wavelength is varying across the length of the filter.
By placing this filter over a multi-pixel detector array, you are separating the light into the various wavelengths.
And that's really what enables getting such a small compact spectrometer. It can't get any smaller than that.
So, all of this can be done at very fast acquisition speeds. I have it set up at 5,000 microseconds, so five-millisecond scan time. And we're going to collect a total of 100 scans, so a total of half a second. We're going to hit the acquire button, and you're going to see a spectrum show up.
I have the spectrometer pointing on some whitish, or yellowish material, hit the acquire button. You're going to see the scan showed up fairly quickly, and in a few seconds, it will say what it is. It's infant formula.
Let's try another one. Hit acquire again, and the red spectrum just showed up. And it will say cornstarch.
There are no moving parts in the spectrometer. The LVF technology itself and the entire package is mechanically and environmentally robust.
It is also available in transmission, as you see in this cell right here, where the detector and the dispersing element are on this end and the light source on this. And you can place the cuvette for the liquid sample in here.
MicroNIR Spectrometer can be used for quantitative as well as qualitative applications, on the go for mobile and handheld applications, as well as online process analyzers for process monitoring and control.
We are very excited about the potential possibilities MicroNIR will enable in the space of NIR infrared spectroscopy. We look forward to hearing from you about your application needs.
