Yuav ua li cas kho lub laser siv ntawm confocal laser scanning microscope
Fais fab tswj qhov rooj qhov teeb tsaNtawm nws mus rau 30% ntawm tus nqi siab tshaj plaws. Cov zis ntau dua shortens laser kev pab cuam lub neej thiab ua rau laser suab nrov. Kho AOTF thiab PMT ua ntej kom tau txais kev pom zoo siv.
Acousto-optic tunable lim muaj nuj nqi Nws tswj cov nqaj excitation thiab siv. Nws hloov laser nyob rau hauv milliseconds thiab kho kev siv ntawm 0% mus rau 100%. Qhov sib txawv laser tsis tuaj yeem siv rau txhua qhov duab taw tes.
Ua hauj lwm hauv paus ntsiab lus nws txais Bragg diffraction nyhuv ntawm suab tsis nyob rau hauv nruab nrab. Xov tooj cua input zaus teeb liab ua rau AOTF difract polychromatic lub teeb thiab xaiv lub teeb monochromatic. Wavelength sib raug rau lub xov tooj cua zaus. Hluav taws xob tuning realizes ceev wavelength switching. AOTF txhawb nqa kev hloov kho laser txuas ntxiv, lub zog hauv zos scanning thiab microsecond-theem hloov.
Nyob rau hauv confocal laser microscope, PMT tsis tuaj yeem nce laser siv tab sis kho cov duab teeb liab zog. Kho PMT voltage hloov cov duab ci. Confocal pinhole loj kuj cuam tshuam qhov ci. PMT yog rhiab heev rau ultraviolet, pom thiab ze-infrared teeb thiab amplifies lub teeb tsis muaj zog rau kev ntsuas.
Kev kho ntawm metallographic microscope
1. Lub chaw soj nstuam yuav tsum muaj peb yam kev tiv thaiv: av qeeg tiv thaiv (tawm ntawm qhov av qeeg), kev ya raws (siv cua txias thiab tshuab ziab khaub ncaws), thiab kev tiv thaiv plua plav (piv rau hauv pem teb); Fais fab mov: 220V+-10%, 50HZ Kub: 0 degree C-40℃C.
2. Tsis txhob hloov lub hom phiaj lo ntsiab muag thaum qhov nruab nrab ntawm lub voj voog ntawm lub voj voog nyob deb ntawm qhov nruab nrab ntawm lub hom phiaj lens, kom tsis txhob khawb lub hom phiaj lens.
3. Thaum tsom, ceev faj tsis txhob cia lub hom phiaj lens kov tus qauv kom tsis txhob khawb lub hom phiaj lens.
4. Txhua qhov kev ua haujlwm hloov yuav tsum yog lub teeb thiab meej.
5. Thaum kho qhov ci ntsa iab, nws yog ib qho tseem ceeb kom tsis txhob muaj kev hloov pauv ntawm qhov ci ntsa iab lossis ci ntsa iab ntau dhau, vim tias nws tuaj yeem cuam tshuam rau lub neej ntawm lub teeb pom kev zoo thiab ua rau pom kev puas tsuaj.
6. Thaum hloov cov roj teeb halogen, ua tib zoo saib xyuas qhov kub thiab txias kom tsis txhob kub hnyiab. Tsis txhob kov lub iav lub cev ntawm lub teeb halogen ncaj qha nrog koj txhais tes.
7. Muab cov khoom siv kho qhov muag uas tsis tshua muaj siv rau hauv lub tais kom qhuav.
Thaum tua lub tshuab ntsuas metallographic, kho qhov ci ntsa iab rau * qis ua ntej muab nws tua.
9. Tsis yog cov kws tshaj lij yuav tsum tsis txhob kho lub teeb pom kev zoo (filament txoj hauj lwm teeb) kom tsis txhob cuam tshuam cov duab zoo.
10. Thaum kaw, kho lub hom phiaj lens mus rau * qis hauv lub xeev los ntawm cov txheej txheem tsom, thiab npog nws nrog plua plav npog tom qab txias. Ua tib zoo saib xyuas kev tiv thaiv hluav taws.
11. Tsis yog cov kws tshaj lij yuav tsum tsis txhob sim so lub hom phiaj lens thiab lwm yam khoom siv kho qhov muag. Cov eyepiece tuaj yeem so nrog cov paj rwb degreased dipped nyob rau hauv ib tug sib tov ntawm 1: 1 kua thiab shaken qhuav. Tsis txhob siv lwm cov kua dej kom tsis txhob ua rau lub qhov muag puas.
