Description

Die Hauptanmeldung bezieht sicn auf ein galileisches Fernglas aus 5 Linsen, das bei einer mindestens dreifachen Vergrößerung ein Bildfeld von wenigstens 240 m auf 1000 m Entfernung gewährleistet, und bei dem das Verhältnis des Objektiv-Durchmessers zur Baulänge mindestens 1 : 1, 4 beträgt.The main application relates to Galilean binoculars 5 lenses that, when magnified at least three times, provide an image field of at least 240 m guaranteed at a distance of 1000 m, and the ratio of the lens diameter to the overall length is at least 1: 1.4.

Die vorliegende Erfindung wandelt derartige Galilei-Gläser in dem Sinne ab, daß die Vergrößerung nur etwa dreifach ist, nämlich zwischen 2,7-und 3,2-fach liegt, daß aber das Gesichtsfeld wenigstens 300m auf 1000 m Abstand beträgt. Dabei ist es möglich, das Verhältnis von Objektivdurchmesser zur Baulänge zwischen 1,0 und 1,3, bevorzugt um 1,1 herum zu wählen.The present invention converts such Galilean glasses into the Sensing that the magnification is only about three times, namely between 2.7 and 3.2 times lies, but that the field of view is at least 300 m at a distance of 1000 m. Included it is possible to change the ratio of the lens diameter to the overall length between 1.0 and 1.3, preferably to choose around 1.1.

Gläser gemäß der Erfindung haben also eine im Verhältnis zum Objektivdurchmesser so kurze Baulänge, daß sie sich leicht in der Tasche oder anderweit unterbringen lassen, oder daß sie gut in Brillengestelle gefaßt werden können.Glasses according to the invention therefore have a ratio in relation to the objective diameter so short that they can be easily put in your pocket or elsewhere let, or that they can be easily grasped in glasses frames.

Auch bei dem Galileiglas gemäß der vorliegenden Erfindung ist die positive Komponente des Objektivs in zwei Linsen aufgespalten, von denen die eine ein freistehender, dem Gegenstand zugekehrter Meniskus ist, während die andere mit einer Zerstreuungslinse aus Flintglas verkittet wurde. Auch hier beträgt die Brechzahl der Sammellinsen mindestens 1,54, bevorzugt 1,57 und mehr, die der Streulinse nicht unter 1,64, bevorzugt etwa 1,70. Auch das Verhältnis der Ny-Werte ist auf mindestens 1,8, zweckmäßig auf mehr als 2 bemessen.Also in the Galileo glass according to the present invention positive component of the lens split into two lenses, one of which one is free-standing meniscus facing the object, while the other is with a diverging lens made of flint glass was cemented. The refractive index is also here the converging lenses at least 1.54, preferably 1.57 and more, those of the diverging lens not below 1.64, preferably about 1.70. The ratio of the Ny values is also at least 1.8, appropriately sized to more than 2.

Das Okular kann gemäß dem Hauptpatent zweilinsig gestaltet sein, es ist hier aber auch möglich, mit einer einzigen Linse auszukommen.The eyepiece can be designed with two lenses according to the main patent, it but it is also possible here to get by with a single lens.

Im folgenden sind drei Beispiele von galileischen Ferngläsern gemäß der Erfindung angegeben : I-IIIII rl + 19,54 + 19,48 + 21,85 dz = 5, 40 5,50 4,85 1, 605/607 r2 + 80, 77 + 81, 59 + 68,31 11 = 0, 1 0,1 0,1 r3 + 34, 80 + 34, 80 + 48,51 d = 6, 05 5, 70 5,40 1,569/63,1 r4-46, 36-42, 97-44, 32 d3 = 1, 30 1,40 1,50 1,699/30.1 r5 + 49, 58 + 50, 81 +107,84 12 =13, 69 13, 88 19, 38 r6-12, 25-12,51-12,64 d4 = 0,90 1,20 1,50 1,487/70,0 r + 22, 41 + 12,51 + 17,29 13 = 1,25 r8-95, 30 d5 = 0,90 1,487/70,0 r9 + 48,506 V = 2, 99 2, 97 2,99 Gesichtsfeld 300 m 315 300 Baulänge 29, 6 27,8 32,7 Durchmesser 27,0 24,6 27,0 Baulänge/ Durchmesser 1,10 1, 13 1,21 Die Figur zeigt einen Querschnitt durch das Galileiglas gemäß Beispiel II.The following are three examples of Galilean binoculars specified according to the invention: I-IIIII rl + 19.54 + 19.48 + 21.85 dz = 5.40 5.50 4.85 1.605/607 r2 + 80, 77 + 81, 59 + 68.31 11 = 0.1 0.1 0.1 r3 + 34, 80 + 34, 80 + 48.51 d = 6.55.70 5.40 1.569 / 63.1 r4-46, 36-42, 97-44, 32 d3 = 1.30 1.40 1.50 1.699 / 30.1 r5 + 49, 58 + 50, 81 +107.84 12 = 13, 69 13, 88 19, 38 r6-12, 25-12.51-12.64 d4 = 0.90 1.20 1.50 1.487 / 70.0 r + 22.41 + 12.51 + 17.29 13 = 1.25 r8-95, 30 d5 = 0.90 1.487 / 70.0 r9 + 48.506 V = 2.99 2.97 2.99 Field of view 300 m 315 300 Overall length 29.6 27.8 32.7 Diameter 27.0 24.6 27.0 Overall length / diameter 1.10 1, 13 1.21 The figure shows a cross section through the Galileo glass according to Example II.
