SPECTRA OF BLUE 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 analysis
Spectrographic analysis of the 473nm Rechargeable Blue Laser; showing *ONLY* the 808nm radiation from the pump diode.


Spectrographic analysis
Spectrographic analysis of the 100mW 473nm DPSS Blue Laser; newer spectrometer software & settings used.


Spectrographic analysis
Spectrographic analysis of the 100mW 473nm DPSS Blue Laser; spectrometer's response narrowed to a range of 450nm to 490nm.


Spectrographic analysis
Spectrographic analysis of the 100mW 473nm DPSS Blue Laser with IR filter removed; newer spectrometer software & settings used.


Spectrographic analysis
Spectrographic analysis of the replacement 473nm Rechargeable Blue Laser.
Different spectrometer used to show all three laser lines simultaneously (at the same time).


Spectrographic analysis
Spectrographic analysis of the replacement 473nm Rechargeable Blue Laser.
Note the 808nm laser line from the pump diode.


Spectrographic analysis
Spectrographic analysis of the replacement 473nm Rechargeable Blue Laser; spectrometer's response narrowed to a range of 468nm to 476nm to pinpoint wavelength.


Spectrographic analysis
Spectrographic analysis of the replacement 473nm Rechargeable Blue Laser; spectrometer's response narrowed to a range of 800nm to 840nm to show emission from the pump diode.


Spectrographic analysis
Spectrographic analysis of the 473nm Rechargeable Blue Laser; different spectrometer (a PC2000-ISA) was used to show all three laser lines simultaneously.


Spectrographic analysis
Spectrographic analysis of the NIR component of the CNI GLP-473nm Blue Laser Pointer, with IR filter removed.
A PC2000-ISA spectrometer was used for this analysis.

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.
