This free online course on the introduction to optical engineering will begin by introducing you to the meaning and background of the geometric optics as well as gaussian beams. You will learn about the importance of studying optics along with how light travels in a homogeneous medium. You will also learn how optical systems are designed as well as the importance of rays of light to the design of optical systems.

This course will also introduce you to the concepts of cartesian ovals and convex-concave as it relates to optical frames. You will learn about a simulation tool referred to as the optic software for layout and optimization (OSLO), as well as the various versions of the tools available for use by designers. This course will teach you to use the OSLO software in optical engineering.

Finally, this course will introduce you to the meaning of aperture stop as well as the optics that limit the cone of light travelling through the system. This course will then improve your knowledge on how to calculate the aperture stop of a system using a very simple Gaussian lens formula along with what causes vignetting in a system. Begin this course and improve your knowledge of optical engineering.
