Help testing 940nm wavelength

[greanbeam]

Might be a long shot, but I'm looking for someone to help test the wavelength on a 7W 940nm C-mount I have. I have a spectrometer that is capable of going up to 920nm. I do get a reading for wavelength beyond that, and have used the # of pixels away from 920nm to get approx 938nm. I'm looking for someone that has a calibrated spectrometer and would be able to quickly verify wavelength. Of course I would compensate for your time.

I have a Burleigh WA-10, which will be much more accurate than any grating based spectrometer. I can also put it on the spectrum analyzer at school if you want to look at the mode pattern. Unfortunately, I don't have a test stand for C-mounts, but for short tests I can just bolt it to a piece of copper and give you the temperature reading.
