Filed:

Aug 31, 1999

Appl. No.:

9/386280

Inventors:

Robert Te Kolste - Charlotte NC
Alan D. Kathman - Charlotte NC

Assignee:

Digital Optics Corporation - Charlotte NC

International Classification:

G02B 676

US Classification:

385 48

Abstract:

A power monitor for a light emitter emitting from a single face creates a monitor beam by deflecting a portion of the application beam and further manipulating the monitor beam to allow more efficient use of the monitor beam. For example, the monitor beam may be collimated to allow an increase in spacing between the light emitter and a detector for sensing the monitor beam. Alternatively or additionally, the monitor beam may be focused to allow use of a smaller detector and of a smaller percentage of the application beam. The diffractive element deflecting the beam may be either transmissive or reflective. The additionally manipulation of the monitor beam may be provided by the same diffractive element which deflects the beam, which is particularly useful when the diffractive element is reflective, and/or by additional optical elements.

Abstract:

A system for utilizing a first vessel connected to a material source and a second vessel connected to a convey line to continuously inject material from the material source into the convey line is disclosed. In illustrated embodiments, the first vessel is connected to the convey line through the second vessel. During a first phase, the first vessel is filled with material from the material source while the second vessels inject material into the convey line. During a second phase, material from the first vessel is injected into the convey line through the second vessel to provide continuous material injection into the convey line.
