Product details

Product Introduction

The MPY-RS terahertz detector is a sensitive and informative terahertz detector, newly launched based on the MPY-01 modelMPY-RS terahertz detector can directly measure pulse repetition frequencyTerahertz signals up to 5KHz, such as the strong field terahertz pulses generated by femtosecond amplifier systems based on 5Hz-5KHz repetition rates, can be directly measured without chopping modulation. meanwhileThe high sensitivity characteristics of MPY-RS pyroelectric detector can also maintain good noise levels.

MPY-RS THz detectorIt can cover wavelengths ranging from ultraviolet (UV) to terahertz (THz), with different windows selected to correspond to different frequency regions.

MPY-RS THz detectorThe signal output can be connected to measurement equipment such as lock-in amplifiers or oscilloscopes through an SMA coaxial line. The detector is shipped with an SMA to BNC adapter.

Terahertz detectors come with low-noise external power supply interfaces, which are superior toMPY-01 terahertz detector, MPY-RSCan provide continuous power supply.
