The new optical receiver iC212 from iC-Haus (Bodenheim, Germany) is the first of its kind that operates throughout a wide input frequency range of DC up to 1.4 GHz, combined with a wide spectral range, making it suitable for measuring things like fast laser diode pulses. The spectral sensitivity ranges from the near ultra violet at 320nm up to the infrared spectrum at 1000nm. The active sensor area of the Si-PIN photo diode with lens measures 0.75mm². This results in a gain of 1.625 V/mW at λ = 760nm. Thus optical power in the sub-mW range can be detected. DC levels at the input can be compensated for by means of an offset trimming feature.
