Optical Power Meters for Telecom
10pW to 3W

Watch How do I measure laser power in telecom applications? video

PD300-IRG

Ophir IRG Optical Power Meters are highly accurate and can measure from picowatts to 3W. Unlike most optical power meters, they can measure either free space beams or fiber coupled beams. Since the beams are coupled from the fiber thru air into the receiver, there are no errors in measurement due to improper fiber mating. The PD300-IRG and 3A-IS-IRG optical power meters are compatible with all Ophir meters and PC interfaces

Fiber coupled

Free space measurement

3A-IS-IRG
