The lens is a transparent, biconvex, crystalline structure placed between iris and the vitreous. . It has got two surfaces: the anterior surface is less convex (radius of curvature 10 mm) than the posterior (radius of curvature 6 mm).. A differentiated lab to test you skill with lab reports and geometric optics. Ray Tracing for Lenses. Lenses are used to focus light and form images. There are a variety of possible types; we will consider only the symmetric ones, the double concave and the double convex.. 3315 The Journal of Experimental Biology 211, 3315-3322Published by The Company of Biologists 2008Multifocal lenses in a monochromat: the harbour sealFrederike D.
