Tsanangudzo yeConcave Lens
Rumwe rudzi rwemalenzi anoshandiswa muhupenyu hwezuva nezuva i lenzi yakakombama. Lenzi yakakombama i lenzi yakatetepa pakati uye yakakora kumicheto. Malenzi akakombama anowanzoita denderedzwa, kunyange zvazvo mamwe asina kudaro. Malenzi akakombama , semuenzaniso, akagadzirwa negirazi kana purasitiki, saka ane refractive index yakakura kupfuura yemhepo.
Mhando
Kazhinji, kune mhando nhatu, apo chimiro chelenzi chinoratidzika semufananidzo uri pazasi (maonero epadivi).
Shandisa
Kana maziso emunhu asingakwanise kuona zvinhu zviri kure zvakajeka kana kuti munhu wacho achiona zviri pedyo, anoshandisa... lenzi yakakombama kana lenzi yakasiyana-siyana kana lenzi isina kunaka kubatsira kuona. Magirazi ekupatsanura anoshandiswa mumagirazi kana magirazi ekupatsanura kuti munhu aone zvinhu zviri kure zvakajeka. Kuwedzera pakushandiswa muzvishandiso zvemaziso zvakaita semagirazi nemagirazi ekupatsanura, magirazi ekupatsanura anoshandiswawo mu chishandiso chekuona chetelesikopu.
Nzvimbo Yekutarisa (F)
Tarisa mufananidzo uri padivi. Mwenje wechiedza unobva kuchinhu chiri kure zvikuru chakadai sezuva wakaenzana nemufananidzo axis huru lenzi. Mumufananidzo, mutsetse webhuruu ndiwo mutsetse mukuru welenzi.
Mwenje wechiedza unorova pamusoro pegirazi rakakombama uye chiedza chinodzorwa negirazi. Kudzorwa kwechiedza nekusiyana kunoteerera mutemo wekusachinja chiedzaMwenje yese yechiedza inodzorwa inoita seinobva panzvimbo yepakati F2 uye mwenje wechiedza wakadzorwa unopararira munzira dzakasiyana-siyana. Mwenje wechiedza wakadzorwa unopararira munzira dzakasiyana-siyana, saka lenzi yakakombama inonzi lenzi yakakombama. lenzi inochinja-chinjaNzvimbo yekutarisa F2 inzvimbo yemumvuri wechinhu chiri kure 
kure kwazvo. Kana chiedza chinodzorwa negirazi rakakombama chichibva kuzuva, mufananidzo wezuva uchaonekwa panzvimbo yakananga F2.
Ziso remunhu rinoona chiedza sechiri kufamba mumutsara wakatwasuka, saka chiedza chakadzorwa chinoita sechinobva panzvimbo yakananga F.2, kunyangwe mwenje wechiedza wakadzorwa usingapfuure nepakati penzvimbo yekutarisa. Nekuti mwenje wechiedza haupfuure nepakati penzvimbo yekutarisa, nzvimbo yekutarisa yelenzi yakakombama inoonekwa kana kuti inoonekwa uye mufananidzo wechinhu chinoonekwa sekunge chiri panzvimbo yekutarisawo unoonekwawo kana kuti unoonekwawo.
Mufananidzo weLenzi Yakasiyana-siyana
Magirazi akasiyana-siyana anogona kuumba mifananidzo chaiyo kana inooneka chete. Mifananidzo chaiyo haipo, asi inoita seyavapo nekuti ziso remunhu rinoona chiedza chichifamba mumutsara wakatwasuka, zvichiita kuti uropi hwemunhu hufunge kuti mufananidzo wacho uripo. Kana skrini ikaiswa panzvimbo inotarisirwa mufananidzo chaiwo, hapana mufananidzo unoonekwa pachiratidziro. Kuumbwa kwemufananidzo wechinhu negirazi rakakombama kwakatsanangurwa zvakadzama munyaya yacho. mufananidzo we lenzi yakasiyana-siyana.
