NARROWBAND SPECTRA OF NEAR-INFRARED (NIR) SOURCES



Ocean Optics USB2000 Spectrometer donated by P.L.
As of 10-10-07, I've been using a PC2000-ISA Spectrometer from Ocean Optics that I received several years ago, but that I didn't have a home for until now.
As of 03-08-08, I once again have the USB2000 spectrometer, enabling color spectra again.

As of 09-19-09, I no longer have the PC2000-ISA; it was sold to prevent an eviction.




NARROWBAND SPECTRA OF NIR (NEAR-INFRARED) SOURCES

Spectrographic analysis
Spectrographic analysis of the NIR LEDs in the Light Relief; newest (01-13-13) spectrometer software settings used. Spectrometer's response narrowed to a band between 830nm and 840nm to pinpoint emission peak wavelength, which is 833.920nm.

The raw spectrometer data (comma-delimited that can be loaded into Excel) is at http://ledmuseum.candlepower.us/42/lightrr.txt
