This work deals with a method for primary optical design of superachromats, where chromatic aberration is corrected for several wavelengths. Equations for the calculation of optical power and curvature radii are described for aplanatic and nonaplanatic optical systems, which are composed of two or three thin lenses in contact. Results of the calculations are presented for chosen optical systems of superachromats with basic design parameters.

Method for primary design of superachromats.

This paper describes an algorithm for designing objectives with separated components for telescopic and collimation systems. Combinations of various types of optical glasses are presented for objective–apochromats obtained using this algorithm. It is confirmed that inexpensive, easy-to-manufacture glasses can be used to obtain apochromatic correction of the image.
