Dual logarithmic photodetector
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Koheron PD10R is a dual logarithmic photodetector for general purpose optical power measurements. In addition to two analog outputs log(A) and log(B), the PD10R gives the log-ratio log(A/B) with an adjustable offset and two gain settings (x1 and x10). The PD10R provides a fully-analog solution for direct absorption measurement in spectroscopy setups.
