Request InfoMKS/NewportNewport Corp. has announced the LIAD series of Lock-In Amplifier Detectors for calibrated power measurement low-level light sources. The detectors use a pyroelectric or photodiode sensor in combination with a built-in lock-in amplifier to reduce noise and drift. They are capable of measuring power down to 300 fW for pulsed light sources with frequencies of 200 Hz or higher. All LIAD Series Lock-in Amplifier Detectors include an 18-Hz chopper that must be placed close to the signal source. The sensor detects the chopped signal only, suppressing all signals not at 18 Hz. The LIAD...See full productRelated content from Photonics MediaPRODUCTSPromoted Content February 2024 IssueFiber Optic De-SpecklerNewport™ fiber optic de-specklers maximize performance and reliability in illumination by eliminating modal interferences for cw to modulation up to 10 kHz, with no optical loss.
