LIAD Lock-in Amplifier Detectors
MKS/NewportRequest Info
The LIAD series Lock-in Amplifier Detectors are ideal detectors for calibrated power measurements of very low-level-light sources. The detectors are used in conjunction with chopped (at 18 Hz) CW or quasi CW radiation, using a digitally synthesized lock-in amplifier to reduce external noise to a minimum. The LIAD-PD-300N Si detector can measure as low as 300 fW at 200 – 1100 nm wavelength range. The pyroelectric-based LIAD-PY-100M can measure down to 100 nW up to 12 μm wavelength.
