The optical power meter single/double channel extinction ratio meter(extinction ratio tester) can independently test polarization extinction ratio, optical power, digital zero, digital calibration, manual or automatic range selection. It is equipped with a USB (RS232) interface. The upper computer software can automatically test, record, and analyze data and quickly form an automatic test system. It is widely used in the test of optical communication equipment, optical fiber, passive optical devices, and active optical devices, with a wide power range, high test accuracy, high-cost performance, and good reliability.

Feature：

 Long life, low noise, low electromagnetic interference

 The measurement error is small

Application：

 Per parameter test of single ended optical device

 Per parameter test of dual output device

(Y-Waveguide, coupler, beam splitter, etc.)
