Default ASEQ LR1 Broad spectral range spectrometer

G'day,

Im looking for a spectrometer to measure me wavelengths, does this look like a go-er?

USB, Broad range spectrometer, fiber input, LabView, VC | eBay



if not, could you recommend one?

Cheers! Fiddy.

Interesting- did you google it?

The sensor is a linear one - you put in a clock signal and it gives an analogue output of each pixel- they must be using a prism or diffraction grating to separate the spectra. You could almsot make one yourself.. Datasheet Here.

Youtube vid of someone pointing a laser pointer at the poor innocent sensor... OK I can't get youtube embedding to work...
Here is the link to it.

The sensor is basically the same one you find in a typical flatbed scanner. Horizontal CCD sensor.

Interesting kit.

Thumbs up Re: ASEQ LR1 Broad spectral range spectrometer

I've been using an Ocean Optics USB2000 spectrometer {link goes to my own web page about it!} since 2006, and it appears to do a rather nice job.

Thankfully, it was donated after the owner of the company who purchased it retired -- God knows I'd never be able to afford one of those critters on my meager disability stipend!
