Great IR Emitter for Harmony Remotes

This LED works excellent inside all Harmony Remotes. Harmony is famous for their IR LED's crapping out! This certainly beats $2.00 apiece at Radio Shack!!!! Thank You All ELEXs!!!!!!!!!

multitouch application

I used 88 of these to build a multitouch display. 11 strings of 8 each in serial with a 5ohm resistor across a 12V computer powersupply. You can see some photos here:

By the way, I was very happy with how quick allelectronicscorp was to send me out some extras when my order of 100 came up a couple shy. +++

Nice LED

The light pattern is hard-edged with a hotter center and outer ring. A diffuser in front of the array will help balance out the hot areas, though.

This is not a very long-range LED. Depending on the sensitivity of your imaging device, the 10-16 mW of radiant power produced by this LED may not be enough. A large array of these will help with the intensity and some experimentation will be necessary to find the right quantity that will provide the proper intensity.

Having a wavelength of 940nm fit my imaging sensor perfectly and is coupled with a 900nm sharp cut filter.

I would have liked a more powerful LED, but the wavelength was more important than power. Using a larger quantity of these LEDs in an array will make up for the low power output. At 20-33 cents per unit, I can live with the need to use a larger quantity in order to meet my wavelength requirements.

IR leds GRATE FOR CHEEP NIGHTVISION

i took one of thos cvs disposible vid cams drilled 8 holes next to the lenz did a simple 1/0 mod to get rid of the HUD and made a kickass night vision camra

A customer from Iowa

Good stuff, maynard

I bought about a dozen of these to do a night vision webcam in my Parrot's cage. They're not as bright as I expected, but very good LED's--the ten I installed will (dimly) brighten up the camera's field of vision. Gonna get another 100 of them.
BTW, use 1.5 volts per LED but no more than 1.7 -- took me forever and 2 dead lights to figure out what that spec sheet was talking about. :D
