LASER/LED LIGHT OUTPUT INTENSITY METER


This circuit uses a large 1cm X 1cm silicon PIN photo diode and a transimpedance Amplifier to measure the light power output of infrared and visible LEDs and laser diodes. It can be modified to produce almost any milliwatts to volts scale factor. It can be connected to either a multi-meter or an oscilloscope.
