Description

The invention relates to a telescopic sight for a telescopic rifle, in particular a hunting rifle.

Telescopic sights are generally known and have an optical system with an integrated aiming device.

The known telescopic sights have a tube which is attached or attachable to the rifle and in which an optical system is accommodated, the optical system having an objective system, an erecting lens system and an ocular system which defines an exit pupil, one after the other in the direction of light. A reticle is arranged in the optical system as a target device.

By AT 409 196 B an optical sight device consisting of two optical subsystems is known, the first optical subsystem of which together with an objective forms a telescopic sight attached to a weapon, while the second optical subsystem forms a night vision device in the form of night vision goggles. According to the information in the publication, the first optical subsystem should have a large exit pupil. The publication does not provide any more detailed information on how this is to be achieved.

US 4105282 A shows and describes a telescopic sight with an exit pupil in a range from 15 to 25 mm.

By DE 10 2006 026 419 A1 a telescope eyepiece is known that has 2 lens groups separated by air in the light direction as the main eyepiece, the first consisting of two cemented lenses and having positive refractive power and the second consisting of a simple converging lens.

By DE 10 2011 001 004 A1 a telescopic sight with an enlarged exit pupil is known which has a distance of the exit pupil from the last glass surface of the vocabulary of at least 90 mm.
By DE 10 2012 205 601 A1 a telescopic sight is known whose construction aims to achieve the largest possible exit pupil or a large distance from the eyepiece.

The invention is based on the object of expanding the possible uses of telescopic sights.

This object is achieved by the invention specified in claim 1.

The basic idea of the invention is to expand the possible uses of a telescopic sight in that the optical system of the telescopic sight is adapted for use with a night vision device.

For the first time, the invention provides a telescopic sight which can be sensibly used with a night vision device in order to support the hunter when aiming. The invention thus also enables hunters whose vision is restricted in twilight to use a telescopic sight. The use of a rifle scope prevents a targeted game from being hit and shot in the desired manner, but only from being shot. The invention is therefore socially useful in the sense of a fair hunt for game.

The use of a telescopic sight with a downstream night vision device has led to results in the prior art which are inadequate for the intended use. The main problem here is the too low light intensity of the image obtained when a telescopic sight is combined with a downstream night vision device.

If the eye adapted to darkness in a young person has an iris diameter of no more than 7 - 8 mm, the objective of a typical night vision device has an entrance pupil diameter of approx. 20 mm and larger. The lens of a night vision device projects the image onto the plane of an electrical detector. Since the illuminance of this image and thus the ability of the device to generate sufficiently bright images on the side of the screen with the eyepiece is related to the square of the effective pupil size, this is generated by the combination of a rifle scope according to the prior art and a night vision device optical image in the first approximation by a factor 8th darker than with a night vision device alone.

Accordingly, the invention provides a telescopic sight, the optical system of which is optimized for use of the telescopic sight with a night vision device. In particular, the invention enables an optical system with an exit pupil with a diameter of 20 mm, which represents a significant advance over the prior art.

Further features and advantages of the invention emerge from the attached claims and the following description of exemplary embodiments.

The meniscus lenses L1 / L2 and L3 / L4 are used to flatten the image field and to minimize the chromatic magnification difference. The meniscus lenses also serve to (partially) suppress the Petzval sum. The meniscus lenses 301/302 and 303/304 are spaced from one another by an air gap. According to the respective requirements, the meniscus lenses of the ocular system 300 also be formed by single menisci.

The lens system 100 is designed in such a way that a telecentric beam path is present on the image side, i.e. at the location of the first intermediate image plane ZBE1. It is also designed such that the object space is imaged in the first intermediate image plane ZBE1 without compensation. Furthermore is the lens system 100 designed for a minimization of the color magnification error and an anastigmatic imaging

The Lens 201 consists preferably of ultra-high refractive index glass and serves to reduce the color magnification error. In the illustrated embodiment, the second erecting system lens group has six lenses in the manner of a double Gaussian construction.
