This web page will be for nothing but spectra of green non-DPSS lasers.
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.
SPECTRA OF DIRECTLY-INJECTED BLUE (470nm to 500nm) LASERS (or, "LAZERS" if you prefer to be incorrect):
Spectrographic analysis of the Directly-Injected 5mW 488nm Greenish-Blue Laser Pen.
Spectrographic analysis of the Directly-Injected 5mW 488nm Greenish-Blue Laser Pen; spectrometer's response narrowed to a band between 475nm and 495nm to pinpoint wavelength, which is 488.710nm.
Spectrographic analysis of the Directly-Injected 5mW 488nm Greenish-Blue Laser Pen; spectrometer's response narrowed to a band between 800nm and 874nm to check for the presence of a pump laser (why bother when I know that a longer wavelength pump laser does not exist?) -- as you can plainly see, it really, truly doesn't exist!!! (I irradiated the spectrometer's sensor quite well in effort to capture this!)
The raw spectrometer data (tab-delimited that can be loaded into Excel) is at 488point.txt
Spectrographic analysis of the Directly-Injected 5mW 488nm Greenish-Blue Laser Pen taken after ~five (5) hours of continuous operation to check for spectral drift; spectrometer's response narrowed to a band between 475nm and 495nm to pinpoint wavelength, which is 488.370nm.

Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at bdf1111@yahoo.com.
Please visit this web page for contact information.
Unsolicited flashlights, LEDs, and other products appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
Be sure to include contact info or your company website's URL so visitors here will know where to purchase your product.
