General Description

Each device in this series is a NPN silicon phototransistor in a hermetically sealed pill package.

The narrow receiving angle provides excellent on-axis coupling.

The OP600 series devices are 100% production tested using infrared light for close correlation with OPTEK GaAs and GaAIAs emitters.
