Intshayelelo emfutshane yomvavanyi wombono wemaski

I-mask visual field tester isetyenziselwa ukuvavanya impembelelo yentsimi ebonakalayo yeemaski, iimaski, izixhobo zokukhusela zokuphefumula kunye nezinye iimveliso.

Ukusetyenziswa kwesivavanyi sombono wemaski:

Isetyenziselwa ukubonwa kwendawo ebonakalayo yeemaski, iziphefumlo, iziphefumlo kunye nezinye iimveliso.

Ukuhlangabezana nemigangatho:

I-GB 2890-2009 Ukhuseleko lokuphefumla oluzincedayo lokuzihluza imaski yegesi 6.8

I-GB 2626-2019 Isixhobo sokukhusela ukuphefumla esizikhuphayo sisihluzo esichasene nentwana yokuphefumla 6.10

I-GB/T 32610-2016 Inkcazo yobugcisa kwiimaski ezikhuselayo zemihla ngemihla 6.12

I-TS EN 136 Ukhuseleko lokuphefumla-iimaski zobuso obugcweleyo-IiMfuneko, uvavanyo, ukumakishwa

Iimpawu zomvavanyi wombono wemaski:

I-1, isikrini esikhulu sokulawula isikrini kunye nokubonisa.

2, uvavanyo oluzenzekelayo kunye neziphumo data.

3. Qwalasela isoftware yohlalutyo lwekhompyutha yekhompyutha.

Iiparamitha zobuchwephesha bemaski Umvavanyi wombono:

I-1, ukubonisa kunye nokulawula: i-intshi ye-7 yombala wesikrini sokuthinta isikrini kunye nokulawula, ukulawula iqhosha lentsimbi elihambelanayo.

I-2, i-radius ye-arc bow (300-340) mm: inokujikelezwa kwinqanaba le-0 °, ukusuka ku-0 ° kumacala omabini kuwo onke ama-5 ° ukusuka kwisikali esongeziweyo ukuya kwi-90 ° isaphetha se-arc inophawu olumhlophe olutyibilikayo.

3. Isixhobo sokurekhoda: Inaliti yokurekhoda idibanisa uphawu olubonakalayo nge-shaft kunye ne-wheel assembly, kwaye irekhoda isalathiso esihambelanayo kunye ne-Angle yophawu olubonakalayo kumzobo webala lokubonwayo.

4, uhlobo lwentloko eqhelekileyo: amehlo amabini umfundi isikhundla isixhobo ibhalbhu umgca vertex kumehlo amabini emva inqaku 7±0.5mm, uhlobo lwentloko eqhelekileyo kwindawo yofakelo itafile yomsebenzi ukuze amehlo asekhohlo nasekunene abekwe embindini wesiqingatha. arc, kwaye ujonge ngqo kwindawo yayo "0".
