Lenzi yeSilicon (Si lenzi) yekushandiswa kweInfrared Mufananidzo Wakaratidzwa

Lenzi yeSilicon (Si lenzi) yekushandisa muInfrared

Mutsetse weinfrared wewavelengthinopa lenzi yesilicon ine saizi dzinozivikanwa kubva pa10mm kusvika 200 mm mudhayamita. Saizi yelenzi inodarika 200mm inogonawo kupihwa kana ukaikumbira. Kuvhara kwedu kwakajairwa kweAR neDLC kwakakodzera bhandi rine 3-5 micron. Kureba kwefocal kwemalenzi edu kwaizodzorwa kusvika kusvika ku +/-1% kushivirira, kupfava kwepamusoro kwe λ/4 @ 632.8nm uye kusarongeka kwepamusoro kwepasi pasi pe 0.5 micron.

Ruzivo rwechigadzirwa:

Lenzi yesilicon igirazi remagetsi rakagadzirwa nesilicon. Silicon (Si) chinhu chakagadzirwa nekristaro chinowanzoshandiswa mumasisitimu emagetsi einfrared anoshanda mubhendi re3 kusvika 5µm spectral. Refractive index yayo iri pedyo ne3.4 muhukuru hwese. Ine densities shoma pakati pezvinhu zvemagetsi zveinfrared, inova hafu yeGe, GaAs neZnSe. Saka zvinhu zvesilicon ndiyo sarudzo yakakodzera kune masisitimu ane huremu. Silicon yakaoma zvakare uye yakachipa pane zvinhu zvakawanda zvemagetsi zveinfrared, inoderedza mutengo wezvinhu uku ichiwedzera mutengo wekugadzira panguva imwe chete.

Silicon yakakodzera kushandiswa kweMWIR asi nekuda kwekunyudzwa kwayo kwakanyanya pamusoro pe6 micron, haina kukodzera kushandiswa kweLWIR. Inogona zvakare kushandiswa segirazi substrate yekushandisa laser nekuda kwekupisa kwayo, huremu hwayo hwakareruka, uye kuoma kwayo.

Infrared yeWavelengthinogona kugadzira lenzi yesilicon ine chimiro chakasiyana-siyananzvimbo dzakatetepa, dzakakombama, dzakakombama, dzisina kusimba uye dzinopararira.Silicon inonyanya kufarirwa kune masisitimu anoshanda munzvimbo ye3-5µm spectral, ine machira anodzivirira kupenya (AR coating), avhareji yekutumira inogona kukwidzwa kusvika pa98%. Tinogona zvakare kuisa dhaimani-senge carbon coating (DLC coating) kana high durable coating (HD coating) pamusoro pe lens kuti tipe dziviriro yakawedzerwa kubva pakukwenya nekukandwa.

Mutsetse weinfrared wewavelengthinogadzira lenzi yesilicon yakagadzirwa nesimbi yakatenderera uye yakabatana. Inogona kutarisa kana kusiyanisa chiedza chinouya kuti chienderane nezvinodiwa zve infrared system.
