    Nanopositionneurs Cryo-XYZ innovants<\/h2>\n\n\n\n

    Renaissance Scientic est une jeune entreprise<\/strong> de Boulder\/CO (\u00c9tats-Unis), qui produit des microscopes cryog\u00e9niques \u00e0 balayage de force (AFM) dot\u00e9s de fonctionnalit\u00e9s avanc\u00e9es uniques, bas\u00e9es sur des nanopositionneurs xyz cryog\u00e9niques ou des scanners de haute pr\u00e9cision et \u00e0 tr\u00e8s faible dissipation thermique. Les moteurs Ren-Sci ont \u00e9t\u00e9 con\u00e7us pour avoir une capacit\u00e9 beaucoup plus faible que les solutions conventionnelles pour les moteurs cryog\u00e9niques.<\/p>\n\n\n\n

    Les moteurs cryog\u00e9niques sont Compatible UHV 1.0\u00d710-11<\/sup> mbar<\/strong>, amagn\u00e9tique par d\u00e9faut (moins de 10nT auto-magn\u00e9tisation<\/strong>), ont tr\u00e8s faibles capacit\u00e9s, jusqu'\u00e0 1 nF \u00e0 4K<\/strong> en (X,Y), ainsi que jusqu'\u00e0 3nF en (Z). Les actionneurs sont rempla\u00e7ables par l'utilisateur et disponibles dans de nombreuses tailles diff\u00e9rentes.<\/p>\n<\/div>\n\n\n\n

    FAIBLES COURANTS - TENSIONS PLUS \u00c9LEV\u00c9ES<\/h2>\n\n\n\n

    Comparez un vendeur<\/strong> sc\u00e9nario, 60 V, 1 kHz, 5 uF, donc la puissance pomp\u00e9e dans ce condensateur est CV^2\/2 fois la fr\u00e9quence, soit ~ 9W. La valeur analogue de pour nos moteurs est de 200 V, 1 kHz, 5 nF, soit 0,1 W<\/strong>et utilise donc 90x moins d'\u00e9nergie pour obtenir le m\u00eame mouvement (et donc 90x moins de dissipation de chaleur).<\/strong><\/p>\n\n\n\n

          Nous avons d\u00e9lib\u00e9r\u00e9ment con\u00e7u nos moteurs de mani\u00e8re \u00e0 ce que les actionneurs puissent \u00eatre remplac\u00e9s par l'utilisateur. Nous fournissons 2 actionneurs suppl\u00e9mentaires par axe.<\/p>\n<\/div>\n\n\n\n

          UHV ET NON-MAGN\u00c9TIQUE PAR D\u00c9FAUT<\/h2>\n\n\n\n

          Tous les moteurs Ren-Sci sont compatibles UHV, peuvent \u00eatre cuits \u00e0 120 \u00b0C et sont fabriqu\u00e9s avec des mat\u00e9riaux non magn\u00e9tiques. En outre, nous avons int\u00e9gr\u00e9 tous ces composants UHV et non magn\u00e9tiques dans notre production, de sorte qu'il n'y a pas de \"surco\u00fbt\" pour avoir ces caract\u00e9ristiques. Aucun lubrifiant n'est utilis\u00e9, qu'il soit \u00e0 l'\u00e9tat solide ou non. Au contraire, nous utilisons des surfaces polies au diamant et une pr\u00e9cision extr\u00eamement \u00e9lev\u00e9e sur nos pi\u00e8ces usin\u00e9es (parall\u00e9lisme inf\u00e9rieur \u00e0 2um sur chaque pi\u00e8ce), de sorte qu'il n'est pas n\u00e9cessaire d'utiliser des lubrifiants.<\/p>\n<\/div>\n<\/div>","protected":false},"featured_media":562,"template":"","meta":{"_acf_changed":true},"application":[9],"manufacturer":[13],"product-category":[6],"class_list":["post-561","product","type-product","status-publish","has-post-thumbnail","hentry","application-cryogenic-equipment","manufacturer-renaissance-scientific","product-category-scanning-probe-microscopy"],"acf":[],"yoast_head":"\nCryo Nanopositioners and Scanners - Schaefer Scientific<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/schaefer-scientific.com\/fr\/produit\/nanopositionneurs-cryo-xyz\/\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Cryo Nanopositioners and Scanners - Schaefer Scientific\" \/>\n<meta property=\"og:description\" content=\"Product Features Innovative Cryo-XYZ Nanopositioners Renaissance Scientic is a young company from Boulder\/CO (USA), producing Cryogenic Scanning Force Microscopes (AFMs) with unique advanced funcionalities, based on Cryogenic xyz-Nanopositioners or scanners with high precision and very low heat dissipation.
