Bi-convex Lenses

Te Lintelo Systems is your partner for Bi-Convex optica lenses made to your special needs, includes various coatings, mirrors, lenses, windows, prisms, polarizing optics, UV and IR optics, optical filters.

Bi-Convex Lenses

Biconvex LensThese 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.
