Mikwoskòp metalijik agrandisman ki ba
1. Aliman limyè a nan mikwoskòp métallurgique
Avèk men gòch la, vire vis ajisteman koryas la pou fè barik lantiy la monte oswa platfòm konpayi asirans lan desann, epi vire konvètisè objektif la pou fè lantiy ki ba-agrandisman an aliyen ak platfòm konpayi asirans lan nan twou limyè a (wotasyon ta dwe fè atansyon pou fè lantiy la objektif pi wo a mank de engraving ak baz la nan bouk la bouk fiks), louvri ouvèti a, Thorne lantiy la pèseptè leve vis, se konsa ke glas la pèseptè sou fen anwo nan avyon an lantiy se yon ti kras pi ba pase wotè nan avyon an nan platfòm la konpayi asirans, de je yo an menm tan an, pandan y ap ajiste direksyon an nan reflektè a jiskaske jaden an de vi nan Limyè a se menm ak klète a se modere.
2. Mikwoskòp metalografikPlasman echantiyon glise
Pran yon echantiyon glise epi mete l sou sèn nan transpòtè ak bò kouvèti a fè fas a anlè, ranje li sou pouse a, Lè sa a, vire vis pouse a alamen aliman echantiyon an yo dwe obsève ak sant la nan Ouverture a.
3. Mikwoskòp metalografikAjiste konsantre a
Vire vis ajisteman koryas la alamen, fè lantiy agrandisman ki ba<6mm from the slide specimen (when adjusting the distance between the objective lens and the slide must be watched from the side, do not turn the coarse adjustment screw at the same time as observing with your eyes on the eyepiece to prevent the lens from colliding with the slide and causing damage), and then open your eyes at the same time, turn the coarse adjustment screw slowly by hand so that the lens rises or make the carrier table fall, when the object image in the field of view is viewed, then adjust the fine adjustment screw until a clear object image appears in the field of view. When the object image appears in the field of view, adjust the fine adjustment screw until a clear object image appears in the field of view. If the object image is not in the centre of the field of view, move the slide specimen up and down, left and right (Note: the direction of movement of the slide is opposite to the direction of movement of the observed object image). If the distance between the lens and the specimen slice has exceeded the working distance when adjusting the focal length and the object image is not seen, then it should be reopened strictly according to the above steps.
