The Wavepower handheld measuring instrument will measure simultaneously both power and wavelength of a laser diode, quickly and simply.
The gain of 5000V/A allows sensitive measurements down to around 4uA.
An integrated offset control allows the compensation of unwanted offset currents which might be superimposing the signal.
Thanks to the real DC coupling, accurate measurements of pulses and digital codes can be performed without unwanted signal over/undershoots and baseline drift which can occur with AC coupled amplifiers.
For use with external photodiodes an adjustable output voltage is provided that allows biasing the detector for higher speed and improved noise performance.
The compact and well shielded metal housing allows use of the amplifier close to the signal source to prevent noise pickup and signal degradation due to long cables.
