Fiber Optics IF PM Digital Photometer
A versatile and economical classroom tool for measuring power levels of laser beams, demodulating optical signals for audio applications and solar experiments. Photometers are essential equipment in any in-school research or principles-of-technical programs. The battery power, portability and adjustable height detector head of this model offer particular flexibility.
The photometer is powered by two standard 9-volt batteries and offers four digital measurement scales from 20 microWatts through 20 milliWatts. Output to industry-standard banana jacks is a conditioned electrical voltage that is directly proportional to light incident upon the photodetector with a frequency range up to 10 kHz. (The analog output can me connected to a strip chart recorder for solar monitoring, to an oscilloscope for observing time-dependent optical signals or to an amplified speaker for voice transmission.) The photometer will also act as output to industry-standard banana jacks.
