Abstract: The invention discloses the device for reduction of off-axis aberrations of imaging optical systems in order to increase the practically useful field of view. This device can be used along with various optical systems, preferably simple ones. It can be placed in front of the optical system as attachable device or embedded in the optical system. The idea is to reduce off-axis aberrations by reduction of the effective aperture for incident off-axis beams depending on the angle of incidence. The device works as angle-dependent aperture stop for the subsequent optical system. This is achieved by the use of special baffles which can be implemented in different ways. For example, these baffles can be implemented in the form of a set of coaxial thin cylindrical tubes of decreasing diameter placed one inside another.

Abstract: The invention discloses the lens system with corrected secondary spectrum without the use of anomalous dispersion optical glasses. The lens system comprises three widely separated lens components. The front lens component of positive refractive power com­prises at least two lenses. The middle lens component comprises at least two lenses. The rear lens component of positive refractive power comprises at least one lens. In the present invention the correction of secondary spectrum is obtained with the use of the most inexpensive optical glasses. The illustrative designs with the use of ordinary crown (BK7) and flint (F2) glasses are presented. Additionally, the illustrative designs with the use of slightly abnormal dense flint glasses are also presented.
