Fluorescence lifetime imaging microscopy (FLIM) excels over the widely used fluorescence intensity imaging by allowing the measurement of absolute signal levels, independent of sensor concentration.

Sun Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then applied in deep ...

A constant current diode provides good temperature stability and does not require any biasing. Some specifications of a laser driver current limit diode (LCLD) include current ranges of 0 to ± 20mA, ± ...

A newly developed air defense laser has 100 percent of incoming threats during a new trial, the U.K. government has said, as several militaries forge ahead with efforts to get lasers operational ...

The key is a possibly gray market very large green laser array. It appears to have at least 24 lasers and some pretty serious lenses. He tested the array first with a power supply and it looked ...
