SPECTRA OF LASER RADIATION
FILTERED THROUGH LASER SAFETY GOGGLES



This web page will be for nothing but spectra of laser radiation filtered through laser safety goggles:

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.

LASER RADIATION FILTERED THROUGH LASER SAFETY GOGGLES:





Spectrographic analysis
Spectrographic analysis of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (2) with the Wicked 445nm LaserShades (2) placed in front of the spectrometer's light input aperture.
That broadband "hump" peaking at ~610nm is fluorescence from the lenses of the glasses themselves.


Spectrographic analysis
Spectrographic analysis of daylight to use as a control.


Spectrographic analysis
Spectrographic analysis of daylight with these glasses placed in front of the spectrometer's light input aperture.














Spectrographic analysis
Spectrographic analysis of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser with the Wicked 445nm LaserShades placed in front of the spectrometer's light input aperture.
That broadband "hump" peaking at ~615nm is fluorescence from the lenses of the glasses themselves.


Spectrographic analysis
Spectrographic analysis of daylight to use as a control.


Spectrographic analysis
Spectrographic analysis of daylight with these glasses placed in front of the spectrometer's light input aperture. Note the sharp decrease in transmission between ~450nm and ~500nm.








Spectrographic analysis
Spectrographic analysis of red laser radiation when filtered through the LaserShades for Red Lasers furnished with my Wicked Lasers Pulsar Red Laser Module.


Spectrographic analysis
Spectrographic analysis of sunlight to use as a control.


Spectrographic analysis
Spectrographic analysis of sunlight with these goggles placed in front of the spectrometer's light input aperture.
Note the cutoff between ~575nm and ~685nm.








Spectrographic analysis
Spectrographic analysis of violet laser radiation when filtered through Unknown-Type (Possibly Violet) Laser Safety Glasses
(Wavelength / type of laser protection they're for is not known -- though they do a fantastic job of attenuating violet laser radiation).

Spectrographic analysis
Spectrographic analysis of outdoor light to use as a control.


Spectrographic analysis
Spectrographic analysis of outdoor light when filtered with these glasses (the glasses were placed in front of the spectrometer's light input aperture).









Spectrographic analysis
Spectrographic analysis of violet laser radiation when filtered through Medical P/C Argon Laser Safety Goggles
; they state an OD (Optical Density) of 5.00 at wavelengths of 515nm and shorter. Note that yellow fluorescence replaces the ~405nm laser line.


Spectrographic analysis
Spectrographic analysis of sunlight to use as a control.


Spectrographic analysis
Spectrographic analysis of sunlight with these goggles placed in front of the spectrometer's light input aperture.
Note the near-sudden cutoff at ~530nm.









Spectrographic analysis
Spectrographic analysis of sunlight to use as a control.


Spectrographic analysis
Spectrographic analysis of sunlight with the Laser Goggles for YAG (1064nm) Lasers placed in front of the spectrometer's light input aperture.
My spectrometer does not read far enough into the infrared to show the cutoff near 1,000nm.










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.
