Opinto-opas

Objective

Students are able to explain and solve problems by drawing and calculating related to the eye, optical instruments and lenses, their problems, function and correction. Areas are (1) refraction at single spherical or plane surfaces, (2) thin lenses, (3) thick lenses, (4) sphero-cylindrical lenses, (5) thin prisms, (6) prismatic effect, and the manipulation of lens form and setting to obtain the desired control of prismatic effect, (7) mirrors.
