A curing device has special application for curing materials used in dentistry which are curable by blue light with a wavelength of 430nm to 500nm. The device has an elongated housing (1), preferably containing a battery (20) as the electrical power source, and a light emitter (2) in the housing comprises one or more blue light emitting, electrically powered, diodes. The power to the diodes is preferably pulsed so the light emitted is of high intensity. Emitted light may pass through a lens (8) on its way to a director (4) such as a mirror (5) or fibre-optic bundle which redirects the light to emerge from the housing at an angle to its length. |
