Photodiode: light sources, the amount of light, and color
I have touched on light sensing methods and the amplification of the signals from them in the past, but at a more fundamental level, how do you choose one? What parameters are important? The answer depends, among other things, on the light source (focused or not), the amount of light and its color. Focused or […]
SMD-packaged violet LEDs put out up to 2.5 W
With up to 2.5 W per single chip, the new violet LEDs from LG Innotek now offer particularly high power in an extremely small space. LASER COMPONENTS sells these 415 nm LEDs at standard (130°) and narrow (55° and 75°) aperture angles. Both versions are integrated in a 3.5 mm x 3.5 mm SMD housing […]
