Key Design has extensive experience with opto-electronics. This covers everything from generating light to detecting or imaging it and the supporting electronics. From visible and infra-red (IR) laser diode drivers (785nm, 905nm & 1550nm), various photodetectors from very high speed small area devices to large area measuring systems. Light source driving circuitry and signal processing circuitry as well as high speed and low speed transimpedance amplifiers can be designed - in fact most electro-optical circuitry.

This expertise is backed up by the custom chip design facilities. Custom ICs for photodiode amplification, multiplexing and scanning can be designed, as well as any signal processing required.
