1.67 MR-7 FSV High Index HMC optical lo ntsiab muag

Lus piav qhia luv luv:

1.67 index lens feem ntau muaj ob yam khoom, MR-7 khoom thiab MR-10 khoom.

Tab sis cov khoom siv MR-7 yog cov khoom siv dav thiab paub zoo tshaj li cov khoom siv MR-10.

MR-7 feem ntau yog siv los ua cov lo ntsiab muag qib siab, nrog rau qhov ntsuas pom ntawm 1.677. Txaus siab rau qhov pom kev zoo dua qub, txawm tias muaj tus lej siab. Piv rau cov lo ntsiab muag ib txwm muaj, MR-7 yog nyias thiab muaj kev nyab xeeb dua. MR-7 kuj yog cov khoom siv nrog cov nyhuv dyeing zoo dua tam sim no. Qee cov xim lo ntsiab muag thiab cov tsom iav tsom iav myopia yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv no.

Qhuav Taw Qhia

Lub refractive index ntawm MR-7 thiab MR-10 cov ntaub ntawv mus txog 1.67, thiab zus tau tej cov high-level lo ntsiab muag yog sib dua thiab nyias. Lub thermal deformation kub ntawm MR-7 yog 85 degrees, thiab MR-10 yog 100 degrees. Ob leeg MR-7 thiab MR-10 yog 1.67 refractive index lens khoom. MR-7 yog qhov yooj yim rau zas dua MR-10, yog li MR-7 yog qhov zoo dua rau cov tsom iav tsom iav, lossis cov lo ntsiab muag zam. MR-10 lo ntsiab muag muaj hardness ntau dua, zoo dua kub ua hauj, thiab ntau dua processability. Lawv feem ntau siv nyob rau hauv kev cob qhia thiab kev cai lens ua.

Feem ntau ntawm cov tsom iav niaj hnub no yog ua los ntawm cov iav lo ntsiab muag. Feem ntau, nyob rau hauv cov ntaub ntawv ntawm tsis zoo tshav kub tsis kam, zaj duab xis nyob rau saum npoo ntawm lub lens yuav tawg, uas yog tshwm sim los ntawm thermal expansion. Piv nrog rau cov zaj duab xis reflective ntawm lub lens, lub degree ntawm thermal expansion ntawm lub hauv paus cov ntaub ntawv yog loj, thiab cov degree ntawm thermal expansion ntawm lub reflective zaj duab xis thiab lub hauv paus khoom yog txawv, thiab cov zaj duab xis tawg yuav tshwm sim.

Raws li qhov kev txiav txim siab no, MR-10 zam qhov teeb meem no txij thaum pib ntawm cov khoom tsim, thiab los ntawm kev txhim kho tas mus li, dhau los ua cov khoom siv nrog cov cua sov zoo thiab tsis tshua muaj thermal expansion coefficient.

Ua ntej, raws li qhov kub thiab txias, qhov thermal expansion coefficient yuav nce, tab sis thermal expansion coefficient ntawm MR-10 yog 25% tsawg dua li ntawm 1.67 cov ntaub ntawv. Piv nrog rau cov khoom siv dav dav 1.67, MR-10 muaj tsawg dua thermal expansion, tsis yooj yim rau kev tawg, thiab tsis tshua muaj kev cuam tshuam los ntawm tshav kub.

Qhov thib ob, thaum qhov kub thiab txias yog 95 ° C, ntau cov kab nrib pleb tshwm sim ntawm cov pa 1.67 lo ntsiab muag, thaum MR-10 tsis cuam tshuam tag nrho.
