Opinto-opas

Objective

After completing this course, students are able to apply the knowledge of physical and geometric optics to describe the eye and the functioning of optical equipment and lenses. They are able to describe the basic physical characteristics of light and calculate and draw the human eye as an optical system. Students can describe the optical factors affecting the quality of the retinal image. Students are able to apply their knowledge of the basics of illumination technology and are capable of offering guidance on choosing appropriate illumination solutions.

Content

Wave theory of light, refraction in the medium, polarization, radiation, wavefront technology, the schematic eye, classification of ametropia, focal point and refractive blur, depth of field, formation and quality of the retinal image, units, measurements and assessment of lighting.
