Product Description

Optical thin Lens - Ilenzi umo ukobvu hwechikamu chepakati chakakura zvichienzaniswa neradii yeku curvature yemativi ayo maviri. Mumazuva ekutanga, kamera yaingove ine convex lens, saka yainzi "single lens". Nekuvandudzwa kwesainzi uye tekinoroji, malenzi emazuva ano ane akati wandei maconvex uye concave lenzi ane mafomu akasiyana uye mabasa ekugadzira lens inotenderera, inodaidzwa kuti "compound lens". Iyo concave lens mu lenzi yekomboni inoita basa rekugadzirisa kwakasiyana siyana.

Features

Girazi reOptical rine kujeka kwepamusoro, kuchena, kusava neruvara, yunifomu magadzirirwo, uye yakanaka refractive simba, saka ndiyo huru mbishi yekugadzira lens. Nekuda kwekusiyana kwemakemikari kuumbwa uye refractive index, girazi remaziso rine:
● Flint girazi - lead oxide inowedzerwa kune girasi yakagadzirwa kuti iwedzere refractive index .
● Korona yegirazi-yakagadzirwa nekuwedzera sodium oxide uye calcium oxide kune girazi rinoumbwa kuti rideredze iro refractive index.
● Lanthanum korona girasi - iyo yakawanikwa yakasiyana-siyana, ine unhu hwakanaka hwepamusoro refractive index uye yakaderera dispersion rate, iyo inopa mamiriro ekugadzirwa kwemahombe-caliber advanced lenses.

Mitemo

Girazi kana chikamu chepurasitiki chinoshandiswa muruminaire kushandura nzira yechiedza kana kudzora kugovera kwechiedza.

Malenzi ndiwo akanyanya kukosha ekuona zvinhu zvinoumba maikorosikopu optical system. Zvikamu zvakaita sechinangwa lens, eyepieces, uye macondensers anoumbwa neamwechete kana akawanda lenzi. Zvinoenderana nechimiro chavo, vanogona kukamurwa kuita mapoka maviri: convex lenzi (positive lenzi) uye concave lenzi (negative lenzi).

Kana danda rechiedza rakafanana neakisi huru ye optical rinopfuura nepakati lens convex uye richipindirana pane imwe nzvimbo, iyi poindi inonzi "focus", uye ndege inopfuura nepakati pekutarisa uye perpendicular kune optical axis inonzi "focal plane. ". Pane nzvimbo mbiri dzakatariswa, nzvimbo yakatarisa munzvimbo yechinhu inonzi "object focal point", uye ndege yakatarisa ipapo inonzi "object focal plane"; Ukuwo, nzvimbo yakatarisa munzvimbo yemufananidzo inonzi "image focal point". Iyo yakatarisana nendege inonzi "image square focal plane".
