SPECTRA OF CHEMICAL LIGHT SOURCES


This web page will be for nothing but spectra of chemical light sticks:

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.

CHEMICAL LIGHT SOURCES (Pg. 1):


Spectrographic analysis of a green-emitting chemical light stick after it had been in operation for at least several hours (I saw it on the counter several hours after a child's birthday party and the first thing that came to mind was, "I wonder if it's still bright enough to perform spectroscopy of?").



Same as above; spectrometer's response narrowed to a band between 505nm and 525nm to pinpoint emission peak wavelength, which is 513.730nm.

The raw spectrometer data (tab-delimited that can be loaded into Excel) is at cls.txt













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 bdf1111@yahoo.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.
