The projection lens is the core component of DMD-based maskless lithography and its imaging quality directly affects the transferal of exposure pattern. Based on the traditional projection lens system, we have designed diffractive optical element (DO

In most textbooks, lens aberrations are usually described in the briefest possible manner, without any attempt for their proper derivation. At the same time, monographs which do go into more detail are often inaccessible to most students and non-spec

A simple algorithm for calculating three-mirror telescopes with all conic surfaces free of spherical aberration, coma, astigmatism, and field curvature is proposed. The algorithm is based on the theory of aberrations of the third order. The initial p

The harmonic sawtooth microstructure allows the diffractive lens to operate with polychromatic radiation, in particular, with the radiation of RGB LEDs, but only with restrictions due to axial color and specific field curvature. Its reason is the jum
