Description

-I

The invention relates to the field of oltika, in particular, to high-aperture lenses used in photography, microphotographs, design and M | Icroprojection technology, when working with television tubes, etc.

A projection lens containing a glued-in double-convex lens and a concave-shaped lens of a head positive lens, a bi-positive lens, a positive lens separated by an air gap, and a negative lens and a positive lens are known;

This lens is a complex structure) C is insufficient, but the correction of ophrochromatism and aberration of wide oblique beams is insufficient.

The closest one to the technical essence of the iK of the invention is a light-shielding lens containing four components, the first of which is pasted over From two-convex and negative lenses, the second and third are pasted over from two. For example, a double layer and a double lens, while the fourth is a single negative lens 2.

The purpose of the invention is to increase. image floor, numeric Interviews in Image Space and Image Quality.

This goal is achieved by the fact that i is equipped with a lens containing four components, the first of which is pasted over from the back and the negative

lenses, the second and third of the double-curved and D1 co-curved lenses, and the fourth is a single separator, the back surfaces of the negative lines of the first And tr-et Ge1 ° 1ShGTShShtT5t 6B:

Thanks to these structural features, it was given to get high-aperture quality with improved image quality and light distribution, with a one and a half times relative HbtiM hole and field of view of the object.
