Abstract

The utility model relates to super-short type optical sighting glasses, which is improved and realized according to the optical theory of the Galileo telescope. The optical system of the utility model is mainly composed of an auxiliary eye lens, a dividing objective lens, a projection objective lens and flat transparent supporting glass. The utility model has the characteristics of short length dimension, light weight, little possibility to be damaged, clear image, etc., and is the practical optical sighting glasses in practice.

Description

Super-short type optical sighting glasses

The utility model is a kind of ultrashort type optical sight.

As everyone knows, the difference of telescope and gun sight is that telescope only is used for the observation to distant objects, and gun sight then is to be used for both distant objects being observed, and can aim at again.The present employed traditional optical sight of people, all in so-called Kepler telescope photosystem, add graduation and realize aiming at, but the shortcoming of this gun sight is owing to will solve the inverted image problem, so must add relay system, generally be lens type or lens type relay system, just inevitably to make the length dimension of optical system relatively long so in design, weight is also bigger, so just brought many inconveniences to use, in actual combat, use carry all not too convenient.On the other hand, though coughing up telescopic system, Jia Li can overcome the long problem of optical system length dimension, only need a negative eyepiece just can become erect image with a positive lens combination, but owing on the centre position of optical system, do not have real image, so can not add graticule in the system, therefore can't be used for aiming.

The purpose of this utility model is on the basis of Galileo telescope optical system, and it is shorter to propose a kind of length dimension, can clearly see the design of Optical System scheme of the optical sight of graduation pattern.

The utility model is achieved in that in the optical system of a Galileo telescope, and projection objective (a 3) fixed in position that is glued on planar transparent supporting glass (2) center is carved with the graduation pattern of band graduation object lens (1) can be imaged on the position of being with on graduation object lens (1) back focal plane between the also painted band graduation object lens (1) of graduation pattern in negative eyepiece (4) and inside surface center.So, because of the front focal plane of negative eyepiece (4) back focal plane with band graduation object lens (1) overlaps in design, and the scenery of infinite distant place also is imaged on its back focal plane through band graduation object lens (1), so viewed at infinity and by human eye through negative order (4) imaging promptly is above a long way off the scenery graduation pattern to be arranged, play aiming and the effect of observing simultaneously, thereby reached the purpose that reduces the gun sight length dimension.

It is very short to the utility model has the advantages that length dimension can design, and uses more conveniently, not fragile in actual combat, and manufacturing cost is also lower.In addition, because the range of choice of graduation pattern color is big,, therefore militarily be relatively to be suitable for so can effectively overcome the influence to graduation clear patterns degree when at times strong and at other times weak of extraneous light.

The utility model has an accompanying drawing, i.e. the ultimate principle sketch of ultrashort type optical sight optical system is among the figure: (1) band graduation object lens, (2) planar transparent supporting glass, (3) projection objective, (4) negative eyepiece.

When the utility model was specifically implemented, the design that the diameter dimension of projection objective (3) should be tried one's best smaller was in the light otherwise can cause the scenery core.Also available several the thinner solid cramp bars of planar transparent supporting glass (2) replace.The graduation pattern can not manufactured where necessary on the inside surface of band graduation object lens (1), and manufactures on the special-purpose graticule of a parallel placement with object lens and optical axis coincidence.The color of graduation pattern can be selected according to different situations, generally uses black proper.The physical construction of ultrashort type optical sight can be finished by general conventional design, can go up design one photic zone in the garden week of band graduation object lens (1) in case of necessity, so that artificial light source is installed, illuminates the graduation pattern, and forming shows the score draws, and is convenient to use night.During specific design, should at first choose each dimensional parameters of galilean telescope system with the method for conventional design, and then carry out projection objective (3) and graduation design of patterns, facts have proved, the graduation pattern adopts garden shape, and color is a black, and effect is more satisfactory.

Claims (1)

1, a kind of ultrashort type optical sight, optical system with Galileo telescope, have negative eyepiece (4), it is characterized in that: projection objective (a 3) fixed in position that is glued on planar transparent supporting glass (2) center is carved with the graduation pattern of band graduation object lens (1) can be imaged on the position on band graduation object lens (1) back focal plane between the band graduation object lens (1) of graduation pattern in negative eyepiece (4) and inside surface center.
