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 GREEN (510nm to 520nm) LASERS (or, "LAZERS" if you prefer to be incorrect):
Spectrographic analysis of this laser after several hours of lasing.
Spectrographic analysis of this laser after several hours of lasing; spectrometer's response narrowed to a band between 500nm and 512nm to pinpoint wavelength, which is 505.410nm.

(I irradiated the spectrometer's sensor quite well in effort to capture this!)

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.
