This course provides a familiarity with precision optical manufacturing and metrology; and an introduction to the materials, machinery, tooling, methods, processes, metrology, and production flow used to fabricate precision optical elements. The optical, thermal, and working properties of common optical materials will be compared. The processes and machinery involved in shaping, finishing, measuring, cleaning, and coating optical components will be described. Strengths and limitations of metrology instruments and methods will be discussed. An overview of the ISO drawing indications will be presented.
This course serves as both successor and tribute to Bob Novak's long-running SC350 Optical Manufacturing Overview course that has been a staple at the Optifab event.
