PDX10R Free-space logarithmic photodetector PDX10R Free-space logarithmic photodetector frequency response

Koheron PDX10R is a logarithmic photodetector for free-space optical power measurements. In addition to two analog outputs log(A) and log(B), it provides the log-ratio log(A/B) with an adjustable offset and two gain settings (x1 and x10). The PDX10R provides a fully-analog solution for direct absorption measurement in spectroscopy setups.
For fiber-coupled photodiodes, see Koheron PD10R logarithmic photodetector.
