Summary
[edit]Description00059 Spettrometro.jpg |
Italiano: Il collimatore S è fissato invariabilmente sul tripode, manca dell'oculare, ed ha nel fuoco dell'obiettivo C una fenditura verticale F, da restringere a piacere mediante la vite V. Il cannocchiale d'osservazione O è girevole insieme con la ghiera H e con l'anello A diviso in gradi: la piattaforma T, che si può alzare ed inclinare a piacere, è girevole dentro l'anello A insieme col circolo K che porta due nonii (I, 154) n, n'. Il movimento a scrupolo del cannocchiale d'osservazione O si effettua stringendo la vite L e girando la M, quello della piattaforma T stringendo L' e girando M'. Il cannocchiale O deve avere il reticolo (148) con un filo verticale nel fuoco dell'obiettivo: deve cioè essere accomodato all'infinito. La fenditura F deve pure essere verticale. Gli assi dei due cannocchiali devono essere perpendicolare all'asse di rotazione comune dell'anello A e della piattaforma T il quale deve essere parallelo allo spigolo del prisma da collocarsi sulla piattaforma. |
