This web page will be for nothing but spectra of 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.
LASERS (or "LAZERS" if you prefer):
Spectrographic analysis of the 780nm 25mW Adjustable Focus Diode Laser Module (the first one of the replacements).
Spectrographic analysis of the 780nm 25mW Adjustable Focus Diode Laser Module (the first one of the replacements); spectrometer's response narrowed to a range of 780nm to 790nm.
As you can see, this laser's peak output is at 785.45nm.
Spectrographic analysis of the 780nm 25mW Adjustable Focus Diode Laser Module (the second one of the replacements).
Spectrographic analysis of the 780nm 25mW Adjustable Focus Diode Laser Module (the second one of the replacements); spectrometer's response narrowed to a range of 780nm to 790nm.
As you can see, this laser's peak output is at 785.45nm -- same as the first!
Spectrographic analysis of the 780nm 25mW Adjustable Focus Diode Laser Module (the second one of the replacements) AFTER it went to pot shortly after the last series of spectrographic analyses were performed on it.
Spectrographic analysis of a defective 780nm 25mW Adjustable Focus Diode Laser Module.
Spectrographic analysis of a defective 780nm 25mW Adjustable Focus Diode Laser Module;
spectrometer's response narrowed to a range between 670nm and 830nm.
Spectrographic analysis of the 300mW 780nm Diode Laser Module.
Spectrographic analysis of the 300mW 780nm Diode Laser Module; spectrometer's response narrowed to a range of 770nm to 790nm.
As you can see, this laser's peak output is at 785.1nm.
Spectrographic analysis of a 50W 808nm Diode Laser Module,
operating ***BELOW*** lasing threshold.
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.
