Optical module for e.g. optical sensor, has support unit comprising support ring, where volume area between section of support ring and cylinder casing surface is filled with pressure resistant sealing compound

摘要

The module (1) has a housing wall section (3) of a pressure resistant housing comprising a passage (5). A mechanical support unit is provided in the passage. A solid body that is transparent to an electromagnetic radiation is provided. The transparent solid body comprises two base surfaces that are opposite to each other and a cylinder casing surface (9). The support unit comprises a support ring (11). A volume area between a section (13) of the support ring and the cylinder casing surface is filled with a pressure resistant sealing compound (25). An independent claim is also included for a pressure resistant housing comprising a housing wall section.
