Optical observation and control devices Magnifiers Continued next page Magnifiers and reading glasses Lens systems Biconvex lens system Biconvex lenses are converging lenses with two outward curved surfaces. They are the simplest and most common form of lenses used in magnifying glasses. In contrast to biconvex lenses, plano-convex lenses have one curved and one plane surface. Plano-convex lenses are used in aplanatic lens systems. (see Aplanatic lens system). Non-spherical lens system The surfaces of a spherical lens constitute a portion of a spherical surface. Non-spherical lenses, in contrast, differ from the spherical shape. Aspherical lenses allow to achieve a relatively higher magnification factor because they minimize the aberrations that are inevitable in the use of lenses. biconvex non-spherical Aplanatic lens system The aplanatic lens system comprises2plano-convex lenses with the convex sides turned inwards and facing each other. One therefore obtains a wider sharp-edge visual field with relatively good magnification. Achromatic lens system The achromatic lens system comprises at least 2 lenses fastened together with putty, with the sides facing each other having equal curves. The lenses are made from optical crown and optical flint. The achromatic system provides a colourless image right up to the edge of the field of vision even with high contrast objects. aplanatic achromatic Testing equipment Continued next page Folding pocket magnifiers Execution: No. 41125 a biconvex folding magnifying glass with a plastic holder, nickel-plated brass cover plates.
