This web page will be for nothing but spectra of RGB (true red/green/blue)-emitting 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.
LASERS (or "LAZERS" if you prefer to be incorrect):
Spectrographic analysis of the "White Light" (RGB) 400mW Laser (all three colors on).
Spectrographic analysis of the "White Light" (RGB) 400mW Laser (red), spectrometer's response narrowed to a band between 645nm and 655nm to pinpoint wavelength, which is 660.660nm.
Spectrographic analysis of the "White Light" (RGB) 400mW Laser (green), spectrometer's response narrowed to a band between 528nm and 538nm to pinpoint wavelength, which is 532.010nm.
Spectrographic analysis of the "White Light" (RGB) 400mW Laser (blue), spectrometer's response narrowed to a band between 450nm and 460nm to pinpoint wavelength, which is 454.700nm.
The raw spectrometer data (comma-delimited that can be loaded into Excel) is at http://ledmuseum.candlepower.us/42/rgbw.txt
Spectrographic analysis of the red laser in the Reke 500RGB Stage Show Projector after ~20 hours to check for wavelength drift: measures exactly 660.0nm.
Spectrographic analysis of the green laser in the Reke 500RGB Stage Show Projector after ~20 hours to check for wavelength drift: measures 531.30nm.
Spectrographic analysis of the blue laser in the Reke 500RGB Stage Show Projector after ~20 hours to check for wavelength drift: measures 441.25nm.
Spectrographic analysis of the red, green, and blue lasers simultaneously (at the same time) in the Reke 500RGB Stage Show Projector.
A second spectrographic analysis of the red, green, and blue lasers simultaneously (at the same time) in the Reke 500RGB Stage Show Projector.
Spectrographic analysis of the red laser in the Reke 500RGB Stage Show Projector.
Spectrographic analysis of the red laser in the Reke 500RGB Stage Show Projector; spectrometer's response band narrowed to a range between 650nm and 670nm to pinpoint wavelength, which is ~660.50nm.
Spectrographic analysis of the green laser in the Reke 500RGB Stage Show Projector.
Spectrographic analysis of the green laser in the Reke 500RGB Stage Show Projector; spectrometer's response band narrowed to a range between 800nm and 850nm to capture the NIR laser line from the pump diode.
Please note that the amplitude is extremely low; it maxes out at approx. 85 vertical counts while most other spectra (including those of lasers) go to 4,096 vertical counts.
Spectrographic analysis of the blue laser in the Reke 500RGB Stage Show Projector.
Spectrographic analysis of the blue laser in the Reke 500RGB Stage Show Projector; spectrometer's response band narrowed to a range between 440nm and 450nm to pinpoint wavelength, which is ~441.65nm.
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 ledmuseum@gmail.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.
