An optical module includes a chamber capable of being evacuated and a mirror in the chamber. The mirror includes a plurality of individual mirrors. Each individual mirror includes: a mirror body including a reflection face; a support structure; and a thermally conductive portion that mechanically connects the support structure to the mirror body. For at least one individual mirror, the thermally conductive portion includes a plurality of thermally conductive strips arranged radially, adjacent thermally conductive strips being separated from each other, and each of the plurality of thermally conductive strips connecting the mirror body to the support structure. For at least one individual mirror, an actuator is associated with the mirror body, the actuator being configured to displace the mirror body relative to the support structure in at least one degree of freedom.

Optical module for guiding a radiation beam

A mirror serves for guiding a radiation bundle. The mirror has a basic body and a coating of a reflective surface of the basic body, the coating increasing the reflectivity of the mirror. A heat dissipating device serves for dissipating heat deposited in the coating. The heat dissipating device has at least one Peltier element. The coating is applied directly on the Peltier element. A temperature setting apparatus has at least one temperature sensor for a temperature of the reflective surface. A regulating device of the Temperature setting apparatus can be connected to the at least one Peltier element and is signal-connected to the at least one temperature sensor. The result is a mirror in which a heat dissipating capacity of the heat dissipating device is improved.

Assembly element made in a plate of brittle material, such as silicon, in particular for a timepiece, including an aperture provided for the axial insertion of an arbour, the inner wall of the aperture including elastic structures which are etched into the plate and which each include at least one support surface for gripping the arbour radially in order to secure the assembly element relative to the arbour. Each elastic structure is formed by a fork which is connected to the inner wall of the aperture by a bridge of material and which includes two branches extending, on either side of the bridge of material, generally towards the arbour. Each branch includes a support surface in proximity to the free end thereof. The invention also proposes a timepiece fitted with an assembly element of this type.

The invention proposes a MEMS micromotor produced in a plate made of crystalline or amorphous material, in particular based on silicon, which comprises a lower layer forming a substrate, and an upper layer in which at least one actuator and a rotor is etched, the actuator driving the rotor in rotation about a shaft (), characterized in that the shaft () is connected to the plate, in that the shaft () extends axially through a hole of the plate, and in that the shaft () is clamped in the hole and centered in the hole by means of elastic fixing structures which are produced by etching in the substrate and which are arranged on the circumference of the hole.

The invention proposes a drive module intended to engage with a clock wheel having a plate made of crystalline or amorphous material comprising a lower layer, which forms a substrate, and an upper layer, into which an MEMS type of micromotor is etched, wherein the micromotor has at least one actuator rotatably driving a rotor, characterized in that a pinion arranged coaxially to the rotor is rotatably connected to the rotor and disposed above the rotor, said pinion being provided to engage with the clock wheel in an engagement zone located close to an outer peripheral edge of the plate, that the rotor is disposed on the plate in order to minimize the distance between the outer peripheral edge of the rotor and the outer peripheral edge of the plate corresponding to the engagement zone, and that the diameter of the pinion is larger than that of the rotor so as to protrude relative to the plate into the engagement zone. The invention also proposes a process for the production of this module and a timepiece comprising such a module.
