About Us
PET was the first company to offer a fully integrated Cell Tester
Based in Ventura, California, Photo Emission Tech., Inc. (PET) started business in 1994. Prior to that the company was doing business as Photo Acoustic Tech., Inc. since 1983. Until recently the company’s main business was manufacturing and marketing Optically Stimulated Electron Emission (OSEE) systems that are used for quantitatively checking surface cleanliness, monitoring, evaluating and optimizing cleaning processes.
In 2001, PET started designing, manufacturing and marketing Solar Simulation Systems and IV Measurement Systems. Solar Simulation Systems simulate the spectra of the sun in the earth’s atmosphere or in space. Applications include testing solar cells, environmental exposure testing and studying of photochemistry / photobiology effects.
PET was the first company to offer a fully integrated Cell Tester. Currently PET has wide range of Solar Simulator models that offer 30mm x 30mm area of illumination to 400mm x 400mm area of illumination. We also offer several models of IV systems that provide a current measuring capability from 1A to 20A. Our systems are the latest design and have the best user interface and control convenience on the market.
