This course provides the background and principles necessary to understanding how optical imaging systems function. Optical system imagery can readily be calculated using the Gaussian cardinal points or by paraxial ray tracing. These principles are extended to the layout and analysis of multicomponent systems. Topics include imaging with thin lenses and systems of thin lenses, stops and pupils, afocal systems, illumination systems, mirrors and prisms, and radiative transfer. Examples of optical systems are described. Simple methods of arriving at, and understanding, the first-order layout of an optical system by a process which determines the required components and their locations are provided. This process will produce an image of the right size and in the right location. A special emphasis is placed on the practical aspects of the design of optical systems.

Intended Audience: 

This course is intended for engineers, scientists, managers, technicians and students who need to use or design optical systems and want to understand the principles of image formation by optical systems. No previous knowledge of optics is assumed in the material development, and only basic math is used (algebra, geometry and trigonometry). By the end of the course, these techniques will allow the design and analysis of relatively sophisticated optical systems.

Learning Objectives: 

This course will enable participants to:

  • Specify the requirements of an optical system for their application including magnification, object-to-image distance and focal length.
  • Diagram ray paths and do simple ray tracing.
  • Describe the performance limits imposed on optical systems by diffraction, the human eye and throughput limits.
  • Predict the imaging characteristics of multicomponent systems.
  • Determine the required element diameters.
  • Apply the layout principles to a variety of optical instruments including telescopes, microscopes, magnifiers, field and relay lenses, zoom lenses, afocal systems, and illumination systems.
  • Adapt a known configuration to suit their application.
  • Understand the process of the design and layout of an optical system.
