FWHM is the angular width of the beam when the intensity at the edge is half the intensity in the center of the beam.
This is a helpful way to classify optics, but it doesn’t take into account the differences between certain optical platforms (different sized diodes).
It is good to know that optics with identical viewing angles can differ quite a lot in intensity and quality of the beam depending on the emitters optical design. On the optics pages on our site, we try to list all the different angles and FWHM for each LED we carry.
The physical size of light sources limit the optical options. Sometimes they are also used with different finishes to add a texture to the light or diffuse it.
With chip-on board (COB) arrays or emitters, they emit such a large area that the only real solution is to surround them with a reflector.
