Course details

Optics is used in many modern technologies, from everyday devices to precise measurement systems. Today, optics is not limited to research labs—it is widely applied in areas like opto-electronics, metrology, and engineering systems that combine optics with electronics and mechanical design.This course introduces the basic ideas of optics in a simple and practical way, suitable for engineering students. It begins with geometric optics, then covers Gaussian optics and wave optics. Real engineering examples are discussed to show how these concepts are used in practice.Along with theory, the course includes a lab component. Students will use optical design software (OSLO) to learn geometric optics through hands-on exercises, and tools like Python or MATLAB to understand wave optics through simulations.
