Abstract
The explosive initiator features an angled fiber optic adapter connected thereto. The initiator includes an elongated tubular cartridge with a longitudinal passageway having input and output ends and an explosive disposed therein downstream of a transparent sealing window and upstream of an output closure. The adapter has an elongated passageway therethrough with input and output ends and divided into a first portion at an angle of preferably 90 degrees from the longitudinal axis of the cartridge and a second portion in line with the cartridge. A mirror lens is positioned in the adapter passageway at the intersection of the two portions for reflecting a light beam from an optical fiber in the inlet end of the adapter to the cartridge passageway and focusing the light beam on the window. Preferably the second portion of the adapter is rotatably mounted to the cartridge. In one embodiment, the first portion is rotatably mounted to the second portion and includes two sub-portions at an angle to each other and bearing a mirror at the intersection thereof. With this arrangement, the initiator can receive an optical fiber from various locations without strain on the fiber.
