An optical scope has at least one optical element which is used to image an object. An optical element is, for example, understood to mean a lens unit, a prism, or a prism system composed of multiple prisms. A lens unit is, for example, understood to mean one single lens or a unit which is composed of at least two lenses. It is provided to make the optical element of glass, namely N-BK7HT, N-SK2HT, F2HT, N-LASF45HT, SF6HT, N-SF6HTultra, N-SF6HT, SF57HTultra, N-SF57HTultra, N-SF57HT, N-LASF9HT and/or N-BAK4HT. The above-named glasses are glasses of the SCHOTT corporation. |

1. An optical scope (1) for imaging an object (O), having
at least one first optical element (17A, 17B, 18A, 18B, 19A, 19B, 21A, 21B, 21C, 21D) made of glass, and having at least one second optical element (17A, 17B, 18A, 18B, 19A, 19B, 21A, 21B, 21C, 21D) made of glass,characterized in that
the first optical element (17A, 17B, 18A, 18B, 19A, 19B, 21A, 21B, 21C, 21D) is made of at least one of the following glass types: N-BK7HT, N-SK2HT, F2HT, N-LASF45HT, SF6HT, N-SF6HTultra, N-SF6HT, SF57HTultra, N-SF57HTultra, N-SF57HT, N-LASF9HT as well as N-BAK4HT;and in that
the second optical element (17A, 17B, 18A, 18B, 19A, 19B, 21A, 21B, 21C, 21D) is made of a lead-containing glass for increasing the transmission. |
