NARROWBAND SPECTRA OF GAS GLOW LAMPS


This web page will be for nothing but spectra of 10mm, 8mm, 5mm, 3mm, and SMD LEDS (driven at 20mA to 60mA; with the exception of the LED in the Motion-Sensing Spotlight):

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.

SPECTRA OF GAS GLOW LAMPS; SPECTROMETER'S RESPONSE BAND NARROWED TO PINPOINT CERTAIN SPECTRAL FEATURES:

Spectrographic plot
Spectrographic analysis of a NE2G green argon ("neon") glow lamp; spectrometer's response narrowed to a band between 500nm and 540nm to show phosphor emission band.


Spectrographic plot
Spectrographic analysis of a NE2G green argon ("neon") glow lamp; spectrometer's response narrowed to a band between 820nm and 840nm to show NIR spectral features.


Spectrographic plot
Spectrographic analysis of an antique GE AR-1 argon glow bulb; spectrometer's response narrowed to a band between 320nm and 380nm to show UV spectral features.


Spectrographic plot
Spectrographic analysis of an antique GE AR-1 argon glow bulb; spectrometer's response narrowed to a band between 670nm and 800nm to show longwave visible spectral features.


Spectrographic plot
Spectrographic analysis of an antique GE AR-1 argon glow bulb; spectrometer's response narrowed to a band between 780nm and 830nm to show NIR spectral features.

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.
