◦These lenses can condense light at a short focal length superior to what can be achieved with spherical lenses.
◦Since these lenses are molded polished from B270-Superwhite, complex shapes that cannot be polished can be easily manufactured.
◦These lenses are designed for the use at infinite conjugate ratios and focal lengths are designed at 587.6nm (yellow helium line [d]).
