602nm led

Apr 30, 2007 3 Replies

I am looking for a source (manufacturere) of 602 nm (600min, 605 max) through hole 3 or 5mm leds. Any help greatly appreciated



Don't know of any that fall directly in that range, but I have a cataolog from SunLED

on my desk that lists some 5 mm LEDs at 590 nm and 607 nm for peak wavelength. There is probably some shift upward in that peak wavelength as the device heats up, so perhaps the 590 running at a specific temperature would go into the range you are looking for. Short of that, you could put a bandpass filter on the 607 nm LED and probably still have some power left in the range you are looking for.

These guys aren't cheap, but they carry almost every LED type in production.

AFIK a LED in standard technology manufacturing (not laser) has a bandwith of about 10 to 20nm. So will be no practicall difference between 600 or 605 nm as long the Spectral Line Full Width is around

5-10nm (could be even more) and difference between Wavelength of Peak Emission and Wavelength of Dominant Emission is always greater than 2...5nm. Why do you care if it's 600 or 605 nm ? :)
