ABSTRACT:
A fiber optic light detector for determining the light intensity of a light emitted from a light source. The device includes a photocell, a light intensity display and two stationary pegs. The two pegs are spacedly positioned about the periphery of the photocell. When measuring light intensity, a fiber optic bundle illuminated by a light source is positioned to cover the photocell and be in contact with both of the two pegs. When the light source is positioned in this manner, complete coverage of the photocell is ensured regardless of the size of the fiber optic bundle. The light intensity display displays the digital value of the intensity determined by the photocell. The light detector is also adapted for connection and concurrent operation with a light source, i.e. a curing light.
