Indangantego ya Plano-convex (PCX) ninzira nziza zifite umubyimba mwinshi hagati ugereranije no ku nkombe, iyo imirasire yegeranijwe inyuramo, urumuri ruhinduka rukagera kumubiri.Lens ya plano-convex ifite uruhande rumwe ruringaniye kandi uruhande rumwe rugoramye hamwe na radiyo nziza yo kugabanuka.Lens ya Plano-Convex ifite uburebure bwiza bwo kwibanda kandi yegera uburyo bwiza kubisabwa bitagira iherezo.Izi lens zibanda kumurongo wegeranijwe kumurongo winyuma no gukusanya urumuri ruva kumurongo.Byashizweho hamwe na sereferi ntoya kandi bifite uburebure bwibanze bwatanzwe na:
f = R / (n-1),
aho R ni radiyo yo kugabanura igice cya convex ya lens na n ni indangagaciro yo kugabanuka.

Lens ya plano-convex itanga kugoreka gake iyo yibanda kubutagira iherezo (mugihe ikintu cyashushanijwe kiri kure kandi igipimo cya conjugate kiri hejuru).Niyo mpamvu rero bajya muri lens muri kamera na telesikopi.Ubushobozi ntarengwa bugerwaho mugihe ubuso bwa plano bwerekeje kumurongo wifuzwa wibanze, muyandi magambo, ubuso bugoramye buhura nibintu byegeranye.Indangantego ya Plano ni amahitamo meza yo gukusanya urumuri cyangwa kwibanda kubikorwa ukoresheje kumurika monochromatic, mu nganda nkinganda, imiti, robotike, cyangwa kwirwanaho.Nibihitamo byubukungu bisaba gusaba kuko byoroshye guhimba.Nkuko bisanzwe bigenda, linzira ya plano-convex ikora neza mugihe ikintu nigishusho biri kumibare yuzuye ya conjugate> 5: 1 cyangwa <1: 5, bityo rero aberration spherical, coma no kugoreka bigabanuka.Iyo icyifuzo cyuzuye cyo gukuza kiri hagati yizi ndangagaciro zombi, lens ya Bi-convex mubisanzwe irakwiriye.

Bitewe nuko ikwirakwizwa cyane kuva 0.18 µm kugeza 8.0 mm, CaF₂Yerekana indangagaciro ntoya itandukana kuva 1.35 kugeza 1.51 kandi ikoreshwa mubisabwa bisaba kwanduza cyane murwego rwa infragre na ultraviolet.Kalisiyumu fluoride nayo yinjizwamo imiti kandi itanga ubukana burenze ugereranije na fluoride ya barium, hamwe na mubyara wa magnesium fluoride.Paralight Optics itanga Kalisiyumu Fluoride (CaF)₂) plano-convex lens hamwe na antireflection yatwikiriye kuri 1,65 µm kugeza 3.0 µm cyangwa 2 µm kugeza 5 µm intera yumurambararo.Iyi coating igabanya cyane impuzandengo yerekana substrate iri munsi ya 1.25%, itanga impuzandengo yo hejuru irenga 95% murwego rwose rwa AR.Reba Igishushanyo gikurikira kugirango ukore.
