Abstract
An optical power monitor comprises a fiber and ferrule assembly telescopically embedded in a first glass tube enclosure and a collimating lens telescopically embedded in a second glass tube enclosure. The two glass tube enclosures are bonded together at their respective facing axial ends. The collimating lens is at a first end substantially adjacent the fiber and ferrule assembly. A second end of the lens is coated with a partially transmissive mirror surface for passing a portion of incident light to a photon detector which is bonded to the second glass tube enclosure.
