Chii chinonzi optical glass?

Optical giraziimhando yegirazi yakanyatsogadzirwa uye inogadzirwa kuti ishandiswe mune akasiyana optical application.Iine zvinhu zvakasiyana-siyana uye hunhu hunoita kuti ive yakakodzera pakugadzirisa uye kutonga kwechiedza, zvichiita kuti kuumbwa uye kuongororwa kwemifananidzo yemhando yepamusoro.

Kuumbwa:

Girasi yeOptical inoumbwa zvakanyanya nesilica (SiO₂) sechinhu chikuru chekugadzira girazi, pamwe chete nezvimwe zvakasiyana-siyana zvemakemikari, zvakadai se boron, sodium, potassium, calcium, uye lead.Iko kusanganiswa kwakananga uye kusungirirwa kwezvikamu izvi zvinotarisa optical uye mechanical properties yegirazi.

Optical Properties:

1.Refractive Index:Girasi yeOptical ine inodzorwa zvakanaka uye yakanyatso kuyerwa refractive index.Indekisi yerefractive inotsanangura kuti chiedza chinokotama sei kana kushandura nzira sezvachinopfuura nepagirazi, zvichikanganisa maitiro ekuona kwemalenzi, maprism, uye zvimwe zvinhu zvemaziso.

2.Kupararira:Dispersion inoreva kupatsanurwa kwechiedza muchikamu chayo chemavara kana mawavelengths apo ichipfuura nepakati pechinhu.Girazi remaziso rinogona kugadzirwa kuti rive nemafambiro chaiwo ekuparadzira, zvichibvumira kugadziriswa kwechromatic aberration mumaoptical systems.

3.Transmission:Optical girazirakagadzirwa kuti rive nepamusoro optical transparency, zvichiita kuti chiedza chipfuure nekunanzva kudiki.Girazi rakagadzirwa kuti rive nemazinga akaderera etsvina uye ruvara kuti riwane yakanakisa kutapurirana kwechiedza muinodiwa wavelength renji.

Optical glass imhando yegirazi

Mechanical Properties:

1.Optical Homogeneity:Girazi reOptical rinogadzirwa kuti rive nepamusoro optical homogeneity, zvichireva kuti ine mauniform optical properties mukati mehuwandu hwayo.Izvi zvakakosha pakuchengetedza mhando yemufananidzo uye kudzivirira kukanganisa kunokonzerwa nekusiyana kwerefractive index pane zvese zvinyorwa.

2.Thermal Kugadzikana:Girazi reOptical rinoratidza kugadzikana kwakanaka kwekupisa, zvichiita kuti rikwanise kumira nekuchinja kwekushisa pasina kuwedzera kukuru kana kuderera.Izvi zvakakosha pakuchengetedza maoptical performance yemalenzi uye zvimwe zvinhu zvemaziso pasi pemamiriro ekunze akasiyana.

3.Mechanical Simba:Kubvagirazi remazisoinowanzo shandiswa mune chaiyo optical masisitimu, inoda kuve neyakakwana simba remagetsi kutsungirira kubata uye kukwira kumanikidza pasina deformation kana kutyoka.Nzira dzakasiyana-siyana dzekusimbisa, dzakadai semakemikari kana maitiro ekupisa, dzinogona kushandiswa kuvandudza maitiro ayo emagetsi.

Izvo zvinhu uye kushandiswa kwegirazi remaziso

Heano mamwe maficha uye mashandisirwo egirazi remaziso:

Features:

1.Transparency:Girazi reOptical rine kujeka kwepamusoro kuchiedza chinooneka uye mamwe mawavelength emagetsi emagetsi.Ichi chivakwa chinochibvumira kufambisa chiedza zvakanaka pasina kukanganisa kukuru kana kupararira.

2.Refractive Index:Girazi reOptical rinogona kugadzirwa neine chaiwo refractive indices.Ichi chivakwa chinogonesa kutonga uye kushandura kwemwaranzi mwenje, ichiita kuti ive yakakodzera kune lenzi, maprism, uye zvimwe zvinhu zvinoonekwa.

Zvimiro zvegirazi remaziso

3.Abbe Number:Nhamba yeAbbe inoyera kupararira kwechinhu, zvichiratidza kuti masaisai echiedza akapararira sei kana achipfuura nemairi.Girazi remaziso rinogona kugadzirwa kuti rive nenhamba dzeAbbe dzakananga, zvichibvumira kugadzirisa kunoshanda kwechromatic aberration mumalenzi.

4.Kuwedzera Thermal Kuwedzera:Girazi reOptical rine yakaderera coefficient yekuwedzera kwekupisa, zvichireva kuti haina kuwedzera kana chibvumirano zvakanyanya nekuchinja kwekushisa.Iyi pfuma inovimbisa kugadzikana uye inodzivirira kukanganisa mu optical system.

5.Chemical uye Mechanical Kugadzikana:Girazi reOptical rakagadzikana mumakemikari uye nemuchina, zvichiita kuti rirambe kumamiriro ezvakatipoteredza senge hunyoro, kushanduka kwetembiricha, uye kushushikana kwemuviri.Uku kusimba kunovimbisa hupenyu hurefu uye kushanda kwemidziyo yemaziso.

Applications:

Optical girazi rinoshandiswa zvakanyanya mune akasiyana optical masisitimu uye zvishandiso, zvinosanganisira:

1.Kamera lenzi:Optical girazichinhu chakakosha mukuvakwa kwemakamera lenzi, inobvumira kunyatsotarisisa, kugadzirisa mufananidzo, uye kurongeka kwemavara.

2.Maikorosikopu uye teresikopu:Girazi reOptical rinoshandiswa kugadzira lenzi, magirazi, maprism, uye zvimwe zvikamu mumamicroscopes uye teresikopu, zvichiita kuti kukwidziswe uye kujeka kwekuona kwezvinhu.

3.Laser tekinoroji:Girazi reOptical rinoshandiswa kugadzira laser makristasi nemalenzi, achibvumira chaiyo laser beam control, kuumbwa kwedanda, uye kupatsanuka kwedanda.

Girazi remaziso rinoshandiswa kugadzira laser crystals

4.Fiber optics: Optical glass fibers anoshandiswa kufambisa data redhijitari pamusoro pemadaro marefu nekumhanya kwakanyanya, achigonesa kutaurirana, kubatana kweinternet, uye kutapurirana data mumaindasitiri akasiyana.

5.Optical filters: Girazi remaziso rinoshandiswa kugadzira mafirita ezvishandiso zvakaita sekutora mifananidzo, spectrophotometry, uye kugadzirisa kwemavara.

6.Optoelectronics: Magirazi emazisos inoshandiswa mukugadzirwa kwemaoptical sensors, zviratidzo, photovoltaic masero, uye mamwe maoptoelectronic madivayiri.

Iyi ingori mienzaniso mishoma yehuwandu hwakawanda hwemashandisirwo uye maficha egirazi yegirazi.Hunhu hwayo hwakasiyana hunoita kuti ive yakakosha munzvimbo dzakawanda dzeindasitiri yeOptical.
