Several parameters determine whether a photodiode or a thermopile sensor is the best choice for a specific application. To help you with this, we compared a silicon photodiode and the gRAY B0.5-SC ...

LASER COMPONENTS has revamped InGaAs and extended InGaAs photodiode technology, which has led to the development of groundbreaking industrial “Plug&Play” sensors. This new class of universal, purely ...

At regular intervals, two LEDs in the sensor head briefly illuminate the underside of the leaf. A photodiode located between those LEDs analyzes the spectrum of the light that is reflected back.

Fig 4. Exposing the modified pressure sensor to laser energy created a temperature-induced change in the piezo-resistive element’s resistance that corresponded directly to laser power.
