1) Nhanganyaya kune Infrared Optics
Infrared Optics inoshandiswa kuunganidza, kutarisa kana kutenderedza mwenje muwavelength renji pakati pe760 ne14,000 nm. Ichi chikamu che IR mwaranzi chakakamurwazve kuita mana akasiyana spectral renji:
| Pedyo neInfrared range (NIR) | 700 - 900 nm |
| Short-Wave Infrared range (SWIR) | 900 - 2300 nm |
| Mid-Wave infrared range (MWIR) | 3000 - 5000 nm |
| Long-Wave infrared range (LWIR) | 8000 - 14000 nm |
2) Short-Wave Infrared (SWIR)
SWIR application inovhara huwandu kubva pa900 kusvika 2300 nm. Kusiyana neMWIR neLWIR mwenje unoburitswa kubva muchinhu pachacho, SWIR inofanana nechiedza chinooneka mupfungwa yekuti mafotoni anotaridzwa kana kutorwa nechinhu, nekudaro ichipa musiyano unodiwa wekufungidzira kwepamusoro. Masikirwo emwenje masosi akadai ambient anotanga mwenje uye kumashure kupenya (aka nightglow) akadai emitters eSWIR uye anopa kuvhenekera kwakanakisa kwekufungidzira kwekunze husiku.
Zviverengero zvezvishandiso zvinonetsa kana zvisingaite uchishandisa mwenje unooneka zvinogoneka uchishandisa SWIR. Paunenge uchifungidzira muSWIR, mhute yemvura, utsi hwemoto, mhute, uye zvimwe zvinhu zvakaita sesilicon zviri pachena. Pamusoro pezvo, mavara anoratidzika kunge akafanana mune anooneka anogona kusiyaniswa zviri nyore uchishandisa SWIR.
Kufungidzira kweSWIR kunoshandiswa kune zvakawanda zvinangwa senge electronic board uye solar cell inspection, kuburitsa kuongorora, kuona uye kuronga, kuongorora, anti-yekunyepedzera, maitiro emhando yekudzora uye nezvimwe.
3) Mid-Wave Infrared (MWIR)
MWIR masisitimu anoshanda mu3 kusvika ku5 micron renji. Paunenge uchifunga pakati peMWIR neLWIR masisitimu, munhu anofanirwa kutora akati wandei kurangarira. Chekutanga, nzvimbo dzemuchadenga dzakaita sehunyoro nehute dzinofanirwa kutariswa. MWIR masisitimu haanyanyi kukanganiswa nehunyoro pane maLWIR masisitimu, saka iwo ari epamusoro kune maapplication akadai sekutarisa kwemahombekombe, ngarava traffic surveillance kana kuchengetedzwa kwechiteshi.
MWIR ine kutapurirana kukuru kwemuchadenga kupfuura LWIR munzvimbo zhinji. Naizvozvo, MWIR inowanzosarudzika kune yakarebesa yekutarisa maapplication anopfuura 10 km chinhambwe kubva pane chinhu.
Zvakare, MWIR iri zvakare sarudzo iri nani kana iwe uchida kuona zvinhu zvinopisa zvakanyanya senge mota, ndege kana makombi. Mumufananidzo uri pazasi munhu anogona kuona kuti kupisa kwemhepo kunopisa kunoonekwa zvakanyanya muMWIR kupfuura muLWIR.
4) Long-Wave Infrared (LWIR)
LWIR masisitimu anoshanda mu8 kusvika 14 micron renji. Ivo vanosarudzwa kune maapplication ane zviri pedyo nekamuri tembiricha zvinhu. LWIR makamera haanyanyi kukanganiswa nezuva uye saka zviri nani kune kunze kwekushanda. Iwo anowanzo asina kunyoroveswa masisitimu anoshandisa Focal Plane Array microbolometers, kunyangwe akatonhodzwa LWIR makamera aripo zvakare uye anoshandisa Mercury Cadmium Tellurium (MCT) detectors. Kusiyana neizvi, mazhinji emakamera eMWIR anoda kutonhora, achishandisa ingave yemvura nitrogen kana Stirling cycle inotonhorera.
LWIR masisitimu anowana huwandu hwakakura hwemashandisirwo akadai sekuongorora zvivakwa uye zvivakwa, kuona kukanganisa, kuona gasi nezvimwe. LWIR makamera akaita basa rakakosha panguva yeCOVID-19 denda sezvo achibvumira kukurumidza uye kwakaringana kuyerwa kwekushisa kwemuviri.
5) IR Substrates Sarudzo Yekutungamira
IR zvinhu zvine zvimiro zvakasiyana izvo zvinovatendera kuti vaite zvakanaka mu infrared spectrum. IR Fused Silica, Germanium, Silicon, Sapphire, uye Zinc Sulfide/Selenide, imwe neimwe ine simba rekushandisa infrared.
Zinc Selenide (ZnSe)
Zinc selenide iine chiedza-yero, yakasimba musanganiswa inosanganisira zinc uye selenium. Iyo inogadzirwa ne synthesis yeZinc vapor uye H2 Se gasi, ichigadzira semashizha pane graphite substrate. Iyo inozivikanwa nekudzika kwayo kunyura mwero uye inobvumira kushandiswa kwakanakisa kweCO2 lasers.
| Optimum Transmission Range | Ideal Applications |
| 0.6 - 16μm | CO2 lasers uye thermometry uye spectroscopy, lenzi, windows, uye FLIR masisitimu |
Germany (Ge)
Germanium ine rima rakasvibira rinopfungaira chitarisiko chine refractive index ye4.024 ine low optical dispersion. Iyo ine dhizaini yakakura ine Knoop Hardness (kg/mm2): 780.00 ichiibvumira kuita zvakanaka kune munda optics mumamiriro akaoma.
| Optimum Transmission Range | Ideal Applications |
| 2 - 16μm | LWIR - MWIR Thermal imaging (kana AR yakavharwa), yakaomesesa optical mamiriro |
Silikoni (S)
Silicon ine yebhuruu-grey kutaridzika ine yakakwirira yekupisa simba inoita kuti ive yakakodzera kune laser magirazi uye silicon wafers kune semiconductor indasitiri. Iyo ine refractive index ye3.42. Zvikamu zveSilicon zvinoshandiswa mumidziyo yemagetsi imhaka yekuti magetsi ayo anogona kupfuura nesilicon conductor nekukurumidza zvichienzaniswa nemamwe maconductor, ishoma pane Ge kana ZnSe. AR coating inokurudzirwa kune akawanda maapplication.
| Optimum Transmission Range | Ideal Applications |
| 1.2 - 8μm | MWIR, NIR imaging, IR spectroscopy, MWIR yekuona masisitimu |
Zinc Sulfidi (ZnS)
Zinc Sulfide isarudzo yakanaka kwazvo ye infrared sensors inoendesa zvakanaka muIR uye inooneka spectrum. Iyo inowanzo mutengo inoshanda sarudzo pane zvimwe IR zvinhu.
| Optimum Transmission Range | Ideal Applications |
| 0.6 - 18μm | LWIR - MWIR, inooneka uye yepakati-wave kana refu-wave infrared sensors |
Sarudzo yako ye substrate uye anti-reflection coating zvinoenderana nekuti ndeipi wavelength inoda kufambisa kwekutanga mukushandisa kwako. Semuenzaniso, kana uri kufambisa IR mwenje muMWIR renji, germanium inogona kunge iri sarudzo yakanaka. Kune NIR zvikumbiro, safiro inogona kunge yakanaka.
Zvimwe zvinotsanangurwa zvaungade kufunga nezvazvo pakusarudza kwako infrared optics zvinosanganisira thermal properties uye index of refraction. Thermal properties ye substrate inoverengera kuti inobata sei pakupisa. Kazhinji, infrared optical elements inozoratidzwa kune tembiricha dzakasiyana siyana. Mamwe maIR application anoburitsawo huwandu hukuru hwekupisa. Kuti uone kana IR substrate inokodzera application yako iwe uchada kutarisa index gradient uye coefficient yekuwedzera kwekushisa (CTE). Kana substrate yakapihwa iine yakakwira index gradient, inogona kunge iine suboptimal optical performance kana ichishandiswa mukupisa kunopisa. Kana iine CTE yakakwirira, inogona kuwedzera kana kubvumirana pamwero wakakwirira wakapiwa kuchinja kukuru kwekushisa. Zvishandiso zvinowanzo shandiswa mu infrared optics zvinosiyana zvakanyanya mu index of refraction. Germany, semuenzaniso, ine indekisi yekuramba ye4.0003, ichienzaniswa ne1.413 yeMgF. Kuwanikwa kwema substrates neiyi hupamhi hwe index yerefraction inopa kuwedzera kuchinjika mukugadzira system. Kuparadzirwa kwezvinhu zveIR kunoyera shanduko yeindex yewavelength maererano newavelength pamwe nechromatic aberration, kana kupatsanurwa kwewavelength. Dispersion inoverengerwa, inversely, nenhamba yeAbbe, inotsanangurwa sereshiyo yerefractive index pad wavelength minus 1, pamusoro pemusiyano uripo pakati peindex yerefraction paf uye c mitsetse. Kana substrate ine nhamba yeAbbe inopfuura makumi mashanu neshanu, haina kupararira uye tinoidaidza kuti korona. More dispersive substrates nenhamba dzeAbbe dzakaderera pane 55 dzinodaidzwa kuti flint materials.
Infrared Optics Applications
Infrared optics ine maapplication mundima dzakawanda, kubva kune yakakwira simba CO2 lasers, inoshanda pa10.6 μm, kusvika kuhusiku-yekuona thermal imaging kamera (MWIR neLWIR mabhendi) uye IR imaging. Izvo zvakakoshawo mu spectroscopy, sezvo shanduko dzinoshandiswa mukuona akawanda ekutsvaga magasi ari munharaunda yepakati infrared. Isu tinogadzira laser mutsara optics pamwe ne infrared zvikamu zvinoita zvakanaka pamusoro pehupamhi hwewavelength renji, uye timu yedu ine ruzivo inogona kupa yakazara dhizaini rutsigiro uye kubvunza.
Paralight Optics iri kushandisa nzira dzepamusoro dzekugadzirisa dzakadai seSingle Point Diamond Turning uye CNC polishing kuti ibudise yakakwirira-chaiyo optical lenses kubva kuSilicon, Germanyium neZinc Sulfide inowana maapplication muMWIR neLWIR kamera. Isu tinokwanisa kuwana hunyanzvi hweasingasviki 0.5 fringes PV uye roughness mune isingasviki 10 nm.
Kuti uwane rumwe ruzivo rwakadzama, ndapota tarisa yeducatalog opticskana kuti inzwa wakasununguka kutibata nesu kuti uwane rumwe ruzivo.
