This optical power meter can convert an optical signal into a voltage signal in high resolution and with an extremely high bandwidth. The design of the optical input enables measuring of the optical signal independent of the position of the optical fiber in the connector.
The device also has a current input. For example, a photodiode can be connected to this input and the diode current converted into a logarithmic voltage signal. Switching between the inputs is done via a button and an LED lights up when the current input is activated. The large wavelength range of the optical power meter enables working in both the visible and infrared range without switching. The precise, logarithmical output signal is ideal for optical alignment systems. The optical power meter is therefore suitable for the fastest fully automatic alignment systems available on the market.
