Alas, I believe you'll have misinterpreted what the information was expressing. Did your datasheet look one thing like this a single?
DaveE claimed: The "brightness" you talk of is integrated from the response of one's visual process; i.e. whole photons collected around some period of time (perhaps 20msec, or so). The PWM method of controlling brightness relies on this, it's going to function at frequencies higher more than enough that You do not recognize the on/off flicker.
Interference designs usually are not restricted to double slit arrangements. A large number of closely spaced parallel slits would make up what is known as a diffraction grating. Lots of spectrometers use diffraction gratings as an alternative to prisms to disperse light into colors. Whereas a prism separates the colours of sunshine by refraction, a diffraction grating separates hues by interference.

I had been also hoping to get the right lenses on the initial consider, as They are really both not cheap directory and get a while to arrive. Many thanks beforehand for any insight!
Borek stated: Two ways of dimming the LED. 1 is to reduce the voltage, then the current goes down and LED gets dimmer (it is in no way relevant to the duty cycle, and as @Averagesupernova talked about, this won't be linear).
Drakkith reported: why Will not you Make contact with someone about at Edmund Optics There is a title I don't forget from my research times!
