Lenzi yegirazi yakaumbwa
Ruzivo rwechigadzirwa:
Magirazi echinyakare e optical anokuyiwa, kukweshwa kuti achinje nzvimbo dzawo kuita mafomu chaiwo, nemamwe mazwi: kuburikidza ne "kugadzira zvinhu zvinotonhora". Kutaura zvazviri, magirazi e optical anogonawo kugadzirwa kuburikidza ne "kugadzira zvinhu zvinopisa", izvo zvinoreva kuumba magirazi akanyatsogadzirwa. Magirazi asina chinhu anoiswa mumipata ye mold, opinda mukupisa, kudzvanya, kunyorovesa uye kutonhora, obva aongororwa uye ounganidzwa.
Nzvimbo yacho ine mhando yepamusoro uye yakarurama; yakagadzirirwa kugadzira lenzi dzine maumbirwo akatarwa. Malenzi akaumbwa ane mwero wepamusoro wekudzokororwa uye kururama, nekuti ese anoenderana nenzvimbo dziri munzvimbo yacho. Maitiro ekuumba anokurumidza kupfuura kugadzirwa kwechando, saka mutengo wekugadzira unogona kudzorwa kusvika padanho rakaderera mukugadzirwa kwakawanda. Kuumba kwakakurumbira zvikuru mumunda wekugadzira lenzi dzemaziso dzakasununguka uye dzakachena.
Hazvisi zvese zvinhu zvegirazi re optical zvakakodzera kugadzira lenzi yegirazi. Zvinhu zvegirazi re optical zvakatevedzana zveTg (Girazi rekuchinja tembiricha) zvakagadzirwa zvakanangana nezvinodiwa pakuumba. Ne refracting index range kubva pa1.4 kusvika 2, zvinogona kusangana nezvinodiwa nekugadzirwa kwemaoptical system akawanda.
Dambudziko guru rekuumba magirazi egirazi nderekuti haagone kushandiswa kugadzira magirazi ane dhayamita yakakura, kunyanya nekuda kwekuoma kwekudziya nekutonhodza zvikamu zvikuru zvegirazi munguva pfupi.
Magadzirirwo
Mutsetse weinfrared wewavelengthinopa lenzi yakaumbwa negirazi ine dhayamita ye1-25 mm. Kusarongeka kwepamusoro pelenzi kunogona kudzorwa kusvika pasi pe0.3 micron, kupatsanurwa kwelenzi kusingasviki 1 arc-minute.
| Zvinhu | Girazi reOptical |
| Dhayamita | 1mm-25mm |
| Chimiro | Aspheric/free-form |
| Kuderedza hunyanzvi | <1 arc-miniti |
| Kusarongeka kwepamusoro | < 0.3 maikironi |
| Aperture yakajeka | >90% |
| Kuputira | Firimu reDielectric/Metallic |
Mashoko:
Kugadziriswa kwechigadzirwa ichi kunowanikwa kuti chienderane nezvinodiwa nehunyanzvi hwako. Tizivise zvaunoda.
