Modification of the Long-Focus Optical Design of the Tair Lens in Order to Increase Manufacturability and Improve Optical Quality

Abstract

The article optimizes the optical scheme of a long-focus achromate with a meniscus corrector Tair (F = 400 mm, 1:4.5) by dividing the labor-intensive meniscus into two simpler lenses and replacing optical materials. The analysis of the dispersion properties of optical glasses from the catalogs of LZOS JSC (Russia) and CDGM (China), which are similar in parameters to those used in the optical scheme of the corrector Tair, is carried out. These materials and their combinations make it possible to improve the optical quality of the original lens. The influence of the choice of lens materials for the Tair lens using the catalogs of LZOS JSC and CDGM on the degree of correction of chromatic aberrations and image quality, described in terms of the modulation transmission function for the visible wavelength range, is investigated. The characteristics of lenses using both the original optical scheme and a modified one using various optical materials are compared. A simplified version of the Tair type lens is proposed, which has a significant advantage in optical characteristics compared to other versions
