*** VERY, VERY IMPORTANT!!! ****This product does not emit light of its own, so the standard review format will not be used and the product will be assigned a rating at once. A very high rating too, as during the time I've had it, it has thus far performed flawlessly.
Also, you must note that a lot of the features of the spectrometer and its software suite go unused, and therefore, unmentioned.
The USB2000 Spectrometer is a very small device (fits in the palm of your hand!) that can provide the spectral content of any UVC, UVB, UVA, visible, or NIR light source (ranging from ~175nm to ~874nm) , using a program called SpectraSuite to show the spectrum on your computer screen in graph format.
It is very important that you install the software on your computer BEFORE plugging the spectrometer in; even more so with the USB version!!!
The USB version plugs directly into any free USB port on your computer.
Here's a screen dump (yes it's really called that) of the SpectraSuite software window.
This program does a lot, but for this website sakes, I have just been taking screen dumps (yes, they're really called that), cropping them so only the spectral window is displayed, saving them in .GIF format (so that they're "web friendly"), and displaying them on this website; like this shining example:
This is the spectrum from an Arc LS Prototype flashlight.
To use the spectrometer, run SpectraSuite first. Once that is running, turn off the lights in the test area until you see a flat red line on the spectral window in SpectraSuite, position the light source to be measured near the port on the side of the spectrometer's body (where you see an indentation in the spectrometer's case), and move it closer to or farther away from this port until the highest point of the spectrum on your computer screen reaches the "4000" level or below. If the light source is too close, the tops of the spectrum will reach the top of the spectral window in SpectraSuite and flatten out - this is your cue to back up the light source so that the light entering the port on the side of the USB2000's body becomes dimmer.
At this point, I just hit the "Print Screen" key on my computer, open a graphics program like IrFanView and then "paste" (CTRL-V)) my screen capture into it (depending on the image viewer software you choose to use, you may ***OR*** may not have to first load any convienient image into it beforehand and then "paste" the screen dump over it). I then crop it so only the spectral window is displayed, save it in .GIF format (so that it's "web friendly"), and display it on this website.
I'm certain there are other methods of data capture, but for my purposes, this is more than sufficient. Like I mentioned earlier, the SpectraSuite program is *FAR* more versatile, but this method works just perfectly for me.
