High Speed Photodiode

kW PowerMax Pro Sensor

kW PowerMax Pro Sensor

…resistance of a thermopile with the response speed of a semiconductor photodiode. The sensor is so fast that a kW laser measurement reaches steady state in less than 100 microseconds with no overshoot. This capability provides nearly instantaneous high power measurement. In traditional kW thermopile…
