Advantest
TQ8210 + Q82017A (TQ82017)

Optical Power Meter, consisting of Advantest's TQ-8210 handheld meter, sensor Q82017A (TQ82017) and charger/wallplug mains adapter.
Advantest's TQ-8210 is a general-purpose portable optical power meter. It uses either a silicon photodiode sensor (for short wavelengths) or an InGaAs or a germanium photodiode sensor (for long wavelengths). A compact sensor facilitates measurements in clamped places. It is suitable for use in R&D applications for optical telecommunications, laser printers, CD equipment and magneto-optical disks.
