Micreascóp metallurgical Úsáid íseal méadaithe
1. An solas micreascóp metallurgical a ailíniú
Leis an lámh chlé, cas an scriú coigeartaithe garbh chun an bairille lionsa a ardú nó an t-ardán iompróra síos, agus ansin an tiontaire oibiachtúil a rothlú chun an lionsa íseal-mhéadaithe a ailíniú leis an ardán iompróra tríd an bpoll solais (ba chóir go mbeadh an rothlú cúramach. déan an lionsa cuspóir os cionn an easpa greanta agus bonn an bhúcla seasta búcla), oscail an cró, rothlaigh scriú ardaithe an lionsa bailitheoir, ionas go mbeidh an scáthán bailitheoir ar thaobh uachtarach an eitleáin lionsa beagán níos ísle ná an airde de plána an ardáin iompróra, an dá shúil ag an am céanna, agus treo an fhrithchaiteora á choigeartú go dtí go bhfuil réimse radhairc an Tá an solas fiú agus tá an gile measartha.
2. Micreascóp miotalagrafaíochtaEiseamal sleamhnáin a shocrú
Glac eiseamal sleamhnáin agus cuir ar stáitse an iompróra é le taobh an chlúdaigh os comhair aníos, é a shocrú ar an bhrúiteoir, ansin cas an scriú brú de láimh chun an t-eiseamal atá le breathnú a ailíniú le lár an chró.
3. Micreascóp miotalagrafaíochtaAn fócas a choigeartú
Cas an scriú coigeartaithe garbh de láimh, déan an lionsa méadaithe íseal<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.
