AVAILABILITY OF DEEP UV LEDS 12-11-06

Ultraviolet wavelength conventions go like this (ranging from longest wavelength to shortest wavelength):

UVA: 390 nm - 320 nm
UVB: 320 nm - 290 nm
UVC: 290 nm - 100 nm
Vacuum UV: 100nm - 10nm




You can obtain Fox Group 350nm and 360nm LEDs from DComponents Corp.

Deep ultraviolet LEDs (those emitting peak wavelengths shorter than ~350nm) are available as of 12-11-06, but they are very expensive.

A 255nm UV LED is available from Roithner Lasertechnik for $474.11 *APIECE!!!* (current, as of 12-11-06).
So LEDs emitting in deep UV wavelengths are not yet inexpensive.

Roithner Lasertechnik is the only place I'm aware of where you can obtain UV and deep UV LEDs with wavelengths shorter than 360nm.







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.
