Abstract

The invention relates to glass capable of being drawn into a tube, in particular to glass capable of being drawn into a tube, which has good hydrolytic stability and good chemical toughening property, and a manufacturing method and application thereof. The glass according to the invention can be used in particular in the LIDAR field, in particular as a LIDAR housing or a LIDAR covering.

Description

technical field [0001] The invention relates to a glass for a drawable tube, in particular to a glass for a drawable tube with good hydrolysis stability and good chemical toughness, as well as a manufacturing method and application of the glass. In particular, the glass according to the invention can be used in the field of LIDAR ("Light Detection and Ranging"), in particular as a LIDAR housing or a LIDAR covering. Background technique [0002] LIDAR systems typically include lasers that emit in the near-infrared range (NIR range), particularly at wavelengths greater than 780 nm. The electromagnetic radiation emitted by the laser is at least partially reflected by objects present around the LIDAR system, and the reflected radiation is recorded by the various sensors of the system. Based on the recorded radiation patterns, the LIDAR system is able to identify objects. The distance can also be determined based on the so-called time-of-flight (ToF) method. Some LIDAR systems...
