Overview & Specifications Related Products Order Now！
SIMTRUM's balanced amplified optical detection module integrates two matching photodiodes and an ultra-low noise transimpedance amplifier, which effectively reduces laser noise and common mode noise, improves the system's signal-to-noise ratio, and has a variety of spectral response options, low noise, high gain, and easy to use. It is mainly used in spectroscopy, heterodyne detection, optical time-lapse measurement, optical coherence tomography and other fields.  

Features

  • Operating Wavelength: 1064, 1310,1550nm (900-1700nm)
  • 3dB bandwidth: 200M, 350M, 400M,1G, 1.6GHz
  • High CMRR and low noise
  • High conversion gain

Applications

  • Coherent detection
  • Optical Tomography (OCT)
  • Doppler laser radar
