LED-eshop.de G-525-1010/B 10mm Green LED
Received 12-31-07, tested 10-18-09
I found this LED in a storage container while looking for other PLS LEDs that required spectroscopy on the newer equipment; that's why the "Received" and "Tested" dates are so far out of whack.

This is a 10mm round through-hole LED that emits a slight whitish green light - this was perfectly expected from a 525nm lamp.
The beam is rather narrow, and consists of a magnified image of the LED's die (light-emitting region), surrounded by a couple of rings. This is a perfectly normal beam from a 10mm narrow-beam non-phosphor LED however, and is nothing whatsoever to be concerned about.



Beam photograph on the test target at 12".
Intensity measures 41,500mcd on a Meterman LM631 (now Amprobe LM631A) light meter.
Vf (forward voltage) is 2.9010 volts at 19.28mA.
Viewing angle is 10°.



Same as above; only the camera & LED were moved a couple of feet back so that the beam shape would be more readily visible.

LED-eshop.de B-485-330 Turquoise Blue LED
Received 11-13-08, tested 10-18-09
Like the LED directly above, I found this LED in a storage container while looking for other PLS LEDs that required spectroscopy on the newer equipment; that's why the "Received" and "Tested" dates are so far out of whack.

This is a 3mm round through-hole LED that emits a slightly greenish blue light - it is specifically designed to be ~15nm longer in wavelength than most other GaN blue LEDs. Peak wavelength was spectrographically measured at 485.50nm - right where it ought to be.


Beam photograph on the test target at 12".
Light is not as blue as this photograph makes it appear.
Intensity measures 1,650mcd on a Meterman LM631 (now Amprobe LM631A) light meter.
Vf (forward voltage) is 3.1070 volts at 19.28mA.
Viewing angle is 30°.

Spectrographic plot
Same as above; spectrometer's response band narrowed to a range of 475nm to 495nm to pinpoint peak wavelength.
