Fused Silica Bi-Convex Lenses

 

These symmetrical lenses also possess positive focal lengths and produce real images of distinct objects. However theses lenses minimize the spherical aberrations for nearly symmetrical positions of the conjugate points with respect to the lens. For exactly symmetrical imaging with a 1:1 magnification not only the spherical aberration is minimized, but also coma and distortion are completely eliminated. As a rule of thumb the bi-convex lenses are best used for magnifications between 1/5 and 5.
