SPECTRA OF YELLOW LASERS


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.
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):

Spectrographic plot
Spectrographic analysis of the Yellow DPSS Laser Module, showing four of the six laser lines (532nm, 593.5nm, 674nm, and 808nm) generated by this laser.
The other two (1,064nm and 1,342nm) and are beyond this spectrometer's range.
Note that the yellow 593.5nm and NIR 808nm laser lines are significantly overloaded on this chart.


Spectrographic plot
Spectrographic analysis of the Yellow DPSS Laser Module, with the spectrometer's response narrowed to a range of 660nm to 680nm to show the ~671nm (measured at ~669.9nm) laser line.


Spectrographic plot
Spectrographic analysis of the Yellow DPSS Laser Module, with the spectrometer's response narrowed to a range of 520nm to 540nm to show the ~532nm (measured at ~531.4nm) laser line.


Spectrographic plot
Spectrographic analysis of the Rigel DPSS Yellow Laser Pointer.

Spectrographic analysis of the Rigel DPSS Yellow Laser Pointer; IR filter removed.
Spectrometer's response narrowed to a range of 790nm to 820nm.


Spectrographic plot
Spectrographic analysis of a Rigel Yellow DPSS Laser Pointer, deliberately "overexposed" to show the weak 532nm and 671nm laser lines.

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.
