Request InfoFemto Messtechnik GmbHThe HBPR series of balanced photodetectors from FEMTO Messtechnik enable the differential measurement of optical signals with wavelengths from 320 to 1700 nm and bandwidths of up to 500 MHz. By taking the exact difference between the two input signals, common-mode noise is suppressed, and the smallest optical signals can be extracted from the signal measurement path. The photoreceivers use two photodiodes selected in pairs, which are connected in an antiparallel and low-noise transimpedance amplifier to detect the differential signal. The optical inputs are optionally free space or...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2022 IssueLadar-Based Metrology SystemThe DYNAMIC 9D laser detection and ranging (LADAR) system from Automated Precision Europe GmbH provides noncontact optical dimensional metrology for manufacturing uses.
