Explore the physics of light, refraction and reflection, the dual ray and wavefront view, and key optical system concepts like apertures, pupils, and first-order ray tracing.
Define the entrance pupil as the image of the aperture stop seen from the object space, and image it through the optics to locate its position, real or virtual.
Use paraxial rays for first-order optics with the small-angle approximation to estimate focal length and aberrations; switch to trigonometric rays for exact wide-angle, off-axis solutions with Zemax.
Compare real rays using exact Snell's law at interfaces with first-order rays, a linear approximation that reveals focus, aberrations, magnification, and the entrance and exit pupils.
Explore invariants in physics and their role in optics and imaging systems. See how conserved quantities like energy, momentum, angular momentum, and charge stay constant across reference frames.
Explore sign conventions in first-order optics: ray height, thickness, and radii of curvature; angles, reflections, and refractive index sign rules; plus primed, unprimed, and barred ray quantities.
Unlock the fascinating world of optics with this comprehensive course designed for beginners and professionals alike. Dive into the core principles of light and optical design, exploring essential concepts that form the foundation of modern optical systems.
This course takes you on a journey through the basics of light behavior, including Snell’s Law and the laws of reflection, to more advanced topics like paraxial rays, marginal rays, and chief rays. You’ll gain a clear understanding of how these rays influence optical performance and the critical roles of the aperture stop, field stop, and sensor format in designing optical systems.
