Isivavanyeli sentsimi yoMbono weMask yeYYT703
Ibhalbhu ene-voltage ephantsi ifakwe kwindawo yeliso le-eyeball yesimo sentloko esiqhelekileyo, ukuze umphezulu we-stereoscopic wokukhanya okhutshwa yibhalbhu ulingane ne-engile ye-stereoscopic yentsimi yombono oqhelekileyo wabantu abadala baseTshayina. Emva kokunxiba imaski, ukongeza, ikhowuni yokukhanya yancitshiswa ngenxa yokuthintelwa kwefestile yeliso lemaski, kwaye ipesenti yekhowuni yokukhanya egciniweyo yayilingana nesantya sokugcinwa kwentsimi yombono yemaski yohlobo lwentloko eqhelekileyo. Imephu yentsimi yombono emva kokunxiba imaski yalinganiswa nge-perimetry yezonyango. Indawo iyonke yentsimi yombono yamehlo amabini kunye nendawo yentsimi ye-binocular yeendawo eziqhelekileyo zamehlo amabini yalinganiswa. Iipesenti ezihambelanayo zentsimi iyonke yombono kunye nentsimi ye-binocular yombono zinokufunyanwa ngokuzilungisa nge-coefficient yokulungisa. Intsimi esezantsi yombono (idigri) imiselwa ngokwendawo yenqaku elisezantsi lokuwela kwimephu yentsimi ye-binocular. Ukuthobela: GB / t2890.gb/t2626, njl.
Le ncwadana ineenkqubo zokusebenza kunye namanyathelo okhuseleko. Nceda ufunde ngononophelo ngaphambi kokufaka nokusebenzisa isixhobo sakho ukuqinisekisa ukusetyenziswa okukhuselekileyo kunye neziphumo zovavanyo ezichanekileyo.
2.1 ukhuseleko
Ngaphambi kokuba usebenzise i-sgj391, nceda ube nesiqinisekiso sokufunda nokuqonda yonke into esetyenziswayo kunye nokhuseleko lombane.
2.2 ukucima kombane ngexesha likaxakeka
Kwimeko yongxamiseko, khupha umbane weplagi ye-sgj391 uze ukhuphe zonke izixhobo zombane ze-sgj391. Esi sixhobo siza kuyimisa uvavanyo.
Irediyasi ye-semicircular arc arch (300-340) mm: inokujikeleza ijikeleze kwicala elithe tye idlula kwi-0 ° yayo.
Imilo yentloko eqhelekileyo: umgca ophezulu webhalbhu yesibane sesixhobo sokuma komfundi yi-7 ± 0.5mm emva kwembindi yamehlo omabini. Imo yentloko eqhelekileyo ifakwe kwibhentshi yokusebenzela ukuze amehlo asekhohlo nasekunene abekwe ngokulandelelana embindini we-semicircular arc arch aze ajonge ngqo kwindawo yayo "0".
Umbane: 220 V, 50 Hz, 200 W.
Imilo yomatshini (L × w × h): malunga ne-900 × 650 × 600.
Ubunzima: 45kg.
