MARKETS
In astronomy, we have worked onthe design and development ofmechatronics and optomechanicsfor IR, multi-object spectrographs,focal planes, optical fiberpositioners and fiber units IFUs.
We have delivered complexprojects for some of the largesttelescopes in the world, such asGTC and VLT (ESO).
MEGARAMEGARA is an optical fiber-fed spectrograph with twoIntegral Field Units (IFU) and a set of robotic positioners forMulti-Object Spectroscopy (MOS) for the 10.4-m GranTelescopio Canarias (GTC) in La Palma. Within the MOS, AVSprovided:
• The positioner system, which consisted of 100 identicalpositioners (8 of them are static and are used for LCBsky substraction) each of them with a fiber minibundleattached (7 fibers each) that patrols a circular area ofØ23,21 mm thanks to the two rotations of the positioner.
• The positioner mechanism control software, whichprovides the low-level control of each positionermechanism.
• The positioner control electronics, which includes thepositioner microcontrollers.
• The cabling between positioners and positioner controlelectronics.
ESPRESSO
ESPRESSO is the Echelle SPectrograph for RockyExoplanets and Stable Spectroscopic Observationsinstalled at the incoherent combined Coudé facilityof the VLT. It is an ultra-stable fibre-fed échellehigh-resolution spectrograph (up to R~190,000).
The work performed for IAC includes fabrication anddetailed design of the Fiberlink, the sub-system thatconnects the telescopes with the instrument. It alsoenables the incoherent combination of light fromthe 4 VLT’s.
MIRADASMIRADAS is an spectrograph that can study many objectssimultaneously and at high spectral resolution. It uses amultiplexing system (MXS) employing deployable probe armswith pick-off mirrors. The primary function of the MXS probemechanism is to select target fields- of-view and relay lightfrom them to the rest of the spectrograph. Each arm patrols asector of the MIRADAS field, just above the input telescopefocal plane.
The arms are mounted on a plate, inside a vacuum jacket and acryogenic dewar, to keep the arm at 114 K.
Each arm consists on two motorized rotations that arecombined to set the probe end at the desired location. Theoptics are mounted inside the arm and the folding mirrors aremade by diamond turning techniques in aluminium parts.
The design of the arm has been done in collaboration with theUniversity of Florida (UF) and includes a detailed considerationof mechanical, thermal, optical and operational effects.
In space, we conceive and develop uniquemechanisms, instruments and robotics for EarthObservation, Exploration, Telecommunication andScience missions, as well as Ground SupportEquipment and In-orbit servicing applications.
We are also working towards a new, extensivecatalogue of space products covering thermalapplications, mechanisms and Electric Propulsionsystems.
MEDAMars Environmental Dynamics Analyzer (MEDA) is a suiteof environmental sensors designed to record dust opticalproperties and six atmospheric parameters.
AVS has developed the mechanisms and structure ofMEDA instrument wind sensors, two wind sensor booms(WS1 and WS2) located at the Remote Sensing Mast (RSM)oriented at 120 degrees from each other to measurewinds approaching the RSM.
The WS1 is a static boom. A HDRM releases thedeployable arm of WS2 after successfully landing and alatching mechanism maintains the position of the sensorat double length than WS1, which will allow MEDA toobtain unique wind measurement.
SUPERCAMSuperCam uses remote optical measurements and laserspectroscopy to determine fine-scale mineralogy, chemistryand atomic and molecular composition of samples encounteredon Mars.
AVS has developed the calibration target (CT) for SuperCamInstrument.
The holder and its sophisticated preloaded system protect a setof 23 samples from the very high shock loads in the surroundingof the CT. The CT also carries the RGB samples and the blackand white samples –protected from dust deposition bymagnets–, and the geometric target. The CT is necessary tocalibrate SuperCam and to obtain invaluable scientificinformation of the Martian rocks.
