Lock-in Amplifier Module Market Overview

A lock-in amplifier module is an amplifier that can extract a signal with a known carrier from extremely noisy environments. It is essentially an analog multiplier followed by a low pass filter. In effect, a lock-in amplifier converts a high-frequency signal into a DC component or very low frequency. It is widely used to measure signals that are otherwise covered by noise.

The U.S. market size is estimated at USD 75 million in 2024, while China’s market is projected to reach USD 50 million in the same year.

The Single Phase segment is expected to reach USD 120 million by 2032, growing at a CAGR of 6.5% during the forecast period 2026–2032.
