FOLDING MAGNIFIERS
When more magnification or a better image is required, multiple-lens magnifiers are used. High power magnifiers are sometimes mounted in a cylindrical or conical holder with no handle. This is called a loupe

The Euromex high-power folding magnifiers can reach up to about 20x, and at these magnifications the aperture of the magnifier becomes very small and it must be placed very close to both the object and the eye. For more convenient use or for magnification beyond about 20x, one must instead use a Euromex microscope

APLANATIC LENS
An aplanatic lens is a lens designed to correct spherical and coma aberration

(Illustration: aplanatic lens)

ACHROMATIC LENS
An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths into focus in the same plane

The achromatic triplet, which is composed of three individual lenses made from glasses with different amounts of dispersion. The lens elements are mounted next to each other and provides the ultimate in distortion-free, color-correct viewing. The triple lens system is made up of two concave meniscus elements cemented to a double convex lens
