LIAD Lock-in Amplifier Detectors
Newport CorporationRequest Info
Ideal for calibrated power measurement of very low-level-light sources, the LIAD detectors are used in conjunction with chopped (at 18 Hz) CW or quasi CW radiation. Wavelengths range from 0.15 to 12 um, power measurement down to 300 fW, and capable of a pulsed source with a 200 Hz or higher frequency. The built-in lock in amplifier reduces noise and drift. A chopper is included.
