Zvikamu zvekamera
Iyo kamera inoumbwa negirazi rekuona lens.Girazi remaziso rakagadzirwa ne-high-purity silicon, boron, sodium, potasium, zinc, lead, magnesium, calcium, barium uye mamwe maokisidhi akasanganiswa maererano neforoma chaiyo, yakanyungudutswa mu platinum crucible pakupisa kwakanyanya, uye ultrasonic Svaira zvakaenzana uye. bvisa mabubbles;ipapo zvishoma nezvishoma kutonhora pasi kwenguva yakareba kuti udzivise kushungurudzika kwemukati mubhokisi regirazi.Iyo yakatonhodzwa girazi block inofanira kuyerwa nezviridzwa zvemaziso kutarisa kana kuchena, pachena, kufanana, refractive index uye dispersion rate inosangana nezvinodiwa.Iro girazi rakakodzera rinopisa uye rinoumbwa kuti rigadzire lens yemaziso isina chinhu.
Iwo anonamira mwenje-anorapa anoshandiswa mukusangana kwemakamera modules uye optical lenses anofanirwa kumira neyakaomarara nharaunda yehunyoro, tembiricha yepamusoro uye simba rakasimba rinowanzo kuwanikwa muzvigadzirwa zvemagetsi, uye zvigadzirwa zvinowanzoda kusangana nemamiriro anotevera:
1. Yakaderera shrinkage: Kuiswa kwekushanda kwekutarisa panguva yekusangana kwekamera module lens base uye bhodhi redunhu rinogona kugadzirisa zvinobudirira dambudziko rekubereka kwechigadzirwa uye kuita kuti lens ibudise yakanakisa kutarisa kwemhando pane iyo yose ndege yemufananidzo.Usati washandisa zvikamu zvakarapwa chiedza, tanga wagadzirisa lenzi katatu-dimensionally, yera nzvimbo yakanakisisa, uye wozopedzisa kurapwa kwekupedzisira nechiedza uye kupisa.Kana shrinkage rate yeadhesive inoshandiswa iri pasi pe1%, hazvisi nyore kukonzera lens position shift.
2. Yakaderera coefficient of thermal expansion: The coefficient of thermal expansion inopfupiswa seCTE, iyo inoreva kugadzika kwemaitiro ejometri yechinhu chinoshanduka nekuchinja kwekushisa pasi pekuita kwekuwedzera kwekushisa uye kuderera.Iyo kamera inoshandiswa kubasa rekunze inogona kusangana nemamiriro ekukurumidza kusimuka / kudonha mukupisa kwemukati.Kana iyo yekupisa yekuwedzera coefficient yekunamatira yakanyanya kukwirira, lens inogona kurasikirwa nekutarisa uye kukanganisa kushanda.
3. Inogona kuporeswa pakupisa kwakadzika: iyo yakasvibirira yekamera module haigoni kubikwa pakupisa kwepamusoro kwenguva yakareba, kana zvisina kudaro zvimwe zvikamu zvinogona kukuvadzwa kana kushanda kuchakanganiswa.Kana iyo yakanamatira inogona kurapwa nekukurumidza pakudzika kwakadzika kwe80 ° C, inogona kudzivirira kurasikirwa kwechikamu uye kugadzirisa goho rechigadzirwa.
4. Kurapa kwe LED: Kuenzaniswa nemidziyo yekurapa yechinyakare, iyo high-pressure mercury rambi nesimbi halide rambi zvine hupenyu hwesevhisi hwe800 kusvika maawa 3,000 chete, nepo chubhu yemwenje yeUV-LED ultraviolet yekurapa michina ine hupenyu hwesevhisi hwe20,000- 30,000 maawa, uye hapana ozone inogadzirwa panguva yekushanda., Iyo inogona kuderedza kushandiswa kwesimba ne70% kusvika 80%.Mazhinji ekunamira-anonamira emwenje anoshandisa LED kurapa midziyo kuti uwane kurapa kwekutanga mumasekonzi matatu kusvika mashanu chete.
