Abstract
A compact pulsed optical source of near to ultraviolet wavelength energy adapted to be connected to an external power source. The optical source includes a device for emitting photons, apparatus for transforming photons into photoelectrons, apparatus for multiplying the photoelectrons, a lens, a phosphor coated anode, circuit apparatus for providing a pulsed electric signal and first and second biasing apparatus. The emitting device impinges photons on the photon transforming apparatus which accelerates electrons to the multiplying apparatus as pulses are received from the circuit apparatus which relates the multiplying apparatus to the transforming apparatus. With each pulse, a cloud of electrons is emitted from the multiplying apparatus and excites the phosphor coated anode thereby causing optical emission.
