  • Optical instrument comprising an entrance cavity in which a mirror is placed
    Patent number: 7855832
    Abstract: The invention relates to an optical instrument (1) comprising at least one mirror called the primary mirror (3), placed in a cavity (2) and comprising an active face capable of being subjected to instantaneous variations of the incident radiative flux. According to the invention, the cavity (2) comprises a rigid internal casing (20) around the mirror consisting of a material having a thermal inertia so as to damp the instantaneous variations of the incident radiative flux thereby making it possible to limit the temperature fluctuations of this cavity and, consequently, the temperature fluctuations of the mirror. The invention applies to the space field.
