The OptoTest OP735 Benchtop Optical Power Meter can be configured with up to 4 channels and a mix of InGaAs, Silicon, and High Power Detectors. This unit is ideal as a compact,  stand-alone power meter or used in conjunction with a stabilized light source to measure insertion loss.

Designed for high speed data acquisition on fiber optic components, the OP735 provides absolute or relative measurements with high resolution and tight linearity specifications.

The unique remote head solution gives the user more flexibility with hard to manage components or bulky fiber optic cables. Our series of detectors include a remote head or an Integrating Sphere which is ideal for bare or ribbon fibers. Adapters are available for all common connector types including FC, ST, SC, LC, etc.
