Tocmai am aflat despre o firma care produce un sistem foarte interesant de deflexie X-Y cu o singura oglinda :

te rog din nou sa citesti toate posturile si toata documentatia.
un rotor special confectionat este mai greu de gasit insa te rog parcurge toata pagina urmatoare si vei putea sa-l confectionezi ieftin si usor :

Foloseste o oglinda obisnuita cat mai subtire sau poti confectiona aceasta oglinda din discurile de HDD. Oglinda originala este totalreflex in RO asa ceva se face la Bucuresti la o firma care se ocupa cu depuneri electro-chimice , dar numai pe comenzi mari.
In constructia unui galvanometru oglinda este ultima piesa de care trebuie sa ti cont .Problema cea mai mare este inertia dupa asamblarea tuturor partilor mobile trebuie sa iasa o inertie foarte mica pentru aceasta trebuie tinut cont de densitatea materialului din care sunt confectionate aceste piese,de dimensiunile lor etc.

foarte important cum bine spune Gigel este greutatea toatala a rotorului si inertia lui.

Despre oglinda : poti folosi la teste o oglinda foarte subtire (de la farduri sau pudriera ...) la care sa stergi cu diluant - cu mare atentie - vopseaua de pe spate. vei avea access la depunerea aluminizata si aceasta sa o pui sa reflecte raza laser.

salut si la multi ani!!!!!!!!!!!
rotorul este confectionat din magnet permanent cu magnetizare diametrala si iti pot procura asa ceva nu se folosesc orice fel de magneti (ia la purificat fizica si studiaza capitolul magneti si magnetism)
iti voi da si ceva documentatie despre cum se realizeaza si ce caracteristici trebuie sa aibe acesti magneti

contacteaza-ma
