Lens for use in incident light microscope, has optical link comprising group of concave and convex lenses, and another optical link satisfying specific condition, where lenses of latter optical link are included by meniscuses

摘要

The lens has an optical link (G1) comprising a front group of concave and convex lenses (L1, L2), and another optical link (G2) comprising a cement link that comprises biconvex lenses (L4, L6) and a biconcave lens (L5), where radio frequencies of the two optical links are 34.5 mm and 38.5 mm. The biconvex and biconcave lenses are included by two meniscuses (M1, M2), where deflections of the meniscuses are oriented towards an image plane (BE). The latter optical link satisfies a specific condition such that a corrected wavelength range lies from 405 nanometer to 700 nanometer.
