摘要： This invention relates to a cooled deformable-mirror and its mount. A deformable mirror is provided comprising a reflective element provided on a substrate that is secured to a deformable element, wherein the substrate comprises at least one channel having a pair of ports both located around the peripheral edge of the substrate. In addition, a deformable-mirror mount and the deformable mirror described above are provided, wherein the mount has a body with a central aperture defined by a supporting surface sized and shaped to support the mirror when installed, and wherein the mount is provided with at least a pair of channels that terminate to face the ports in the mirror when the mirror is installed, the channels of the mirror and the mount being connected via flexible seals.

摘要： This invention concerns improvements relating to a deformable-mirror holder for holding a mirror in a desired position, to within accepted tolerances, even whilst the mirror is deforming or in a deformed state. More particularly but not exclusively, this invention relates to a holder for a bimorph mirror. A deformable mirror holder (31) is provided comprising a body with a receiving portion for receiving a deformable mirror (30), and wherein the receiving portion is defined by a passive flexible support structure (41) such that, in use, to the support structure provides a supporting surface to the mirror. This invention extends to a deformable mirror and a deformable mirror holder as described above.

摘要： A TEM mode resonator includes a tuneable cavity defined by an electrically conducting cavity wall. The cavity wall includes a grounding face, a capacitor face and a surrounding wall extending therebetween. An electrically conducting resonator member is disposed within the cavity and extends from the grounding face part way towards the capacitor face. A portion of the resonator member proximate to the capacitor face includes a recess defining an aperture. A tuning mechanism disposed outside the tuneable cavity, includes a tuning arm extending into the tuneable cavity through the aperture. The tuning mechanism is adapted to displace the tuning arm towards and away from the capacitor face. At least a portion of the tuning arm disposed within the cavity is the tuning element, which is formed of either a metal or a dielectric.
