Mounting of Optical Components

Level: Introductory Length: 7 hours Format: In-Person Lecture Intended Audience: Intended for engineers (mechanical, optical, electrical, and systems), scientists, technicians, and managers who are developing, specifying, or purchasing optical, electro-optical, infrared, or laser systems. The material is at an introductory level, but a basic familiarity with optomechanical engineering principles is useful. Description: This course introduces the optomechanical engineering principles for the mounting of optical components such as lenses, mirrors, windows, prisms, and filters. Oriented towards practicing engineers and managers, case studies are used to show how mount design is driven by a combination of environmental, performance, and cost requirements. Standard industry practices and common mounting techniques are reviewed, including: • Mounting of lenses into barrels using adhesives or retaining rings • Mounting of prisms and small mirrors using adhesives or clamps • Mounting of assemblies using flexures • Mounting and sealing of windows Without using finite-element analysis (FEA), first-order engineering estimates are used to predict the performance of various mount types. Learning Outcomes: This course will enable you to: - design mounts that balance performance, survivability, and cost - estimate optomechanical tolerances for optical assemblies using standard designs - identify critical aspects of the optic-to-mount interface - isolate the effects of the environment on optics - estimate survivability for vibration and thermal loading - compare alternate low-strain mounting techniques for common types of elements Instructor(s): Keith J.
