Performance Parameters

Figure 3-1 Summary of Electrical Performance

Notes:

Do not exceed 1mW for the maximum optical input power of the PD.

If the input is DC light, the optical power measured by the power meter is equal to the maximum optical power.

If the input is other types of light (e.g., pulsed light), the maximum optical power is calculated as the average optical power divided by the duty cycle. For example:

If the average optical power is 1mW and the duty cycle is 0.1%, the maximum optical power is 1W.

If the input is a square wave with a 50% duty cycle, the maximum optical power is 2mW.

If you are unsure whether the optical power will damage the detector, it is recommended to add an attenuator before the laser light enters the PD. First, minimize the light intensity, then observe the oscilloscope waveform, and gradually increase the optical power. The optimal condition is that the signal amplitude displayed on the oscilloscope does not exceed 500mVpp.
