940nm yakaratidza ziso rakachengeteka?

940nm LED inogona kuve package ine SMD LEDTY RENYU uye yakatungamira marambi emwenje. Asi panguva yekushandisa, mwenje weIr unotungamirwa muna 940nm wavelength yakachengeteka?

Kuchengeteka kwe940 NM (Nanometer) Wavelength Kuti uone kana 940 nm iri ziso, rakakosha kuti unzwisise chimiro cheiyi wavelength, kudyidzana kwayo neziso, uye maitiro ekuchengetedza anoenderana nayo. "
Infrared mwenje inodonha mukati meiyo electromagnetic spectrum, ine wavelengths kwenguva yakareba kupfuura izvo zvechiedza chinoonekwa. Ziso revanhu rinotaridzika kune mavheti kubva pamatanho osvika 400nm LED Wavelength (Violet) kusvika 730nm LED Wavelength Pamusoro peiyi renji, mwenje unoisa usingaonekwi neziso rakashama. Nekudaro, izvi hazvireve kuti hazvigone kukanganisa ocular tishu.
Iko kukuvara kunogona kunokonzerwa nekuratidzwa kwerudzi rwunoratidzwa zvinoenderana nezvinhu zvakasiyana-siyana zvakadai sekusimbisa, kuratidzira nguva, uye kunzwira tsitsi kweocular tishu kune iyo chaiyo wavelength. Panyaya ye940 NM, inowanzoonekwa seye ziso-yakachengeteka pasi pemamiriro ezvinhu ekushanda.
Chikonzero chikuru chekuchengetedzeka kwemaziso e940 nm ndeyekunyura kwayo kwakaderera neiyo cornea, lens, uye retina. Iyo Cornea, iri yekunze kweziso, inoita seyakavharirwa zvipinganidzo pamusoro pezvinhu zvekunze uye zvakawandisa. Iyo inobata yakawanda yeUV mwenje yeUV uye chikamu chakakosha chechikamu chipfupi chimbichimbi chiedza chinoonekwa, asi chinojeka kusvika 940 nm infrared mwenje.
Saizvozvo, lens, iri kuseri kweCornea, inobata UV mwenje uye imwe mwenje unooneka, asi zvakare yakajeka yekubvisirwa mwenje, kusanganisira 940 nm. Iyo retina, iyo ndiyo yechiedza-chinonaka-tarisiro tishu kumashure kweziso, ndiko kunetseka kwakanyanya kana zvasvika pakuchengetedza ziso. Nekudaro, na940 nm, retina zvakare inonyatso kusanzwisisa, kuderedza njodzi yekukuvara.
Izvo zvakakosha kuti uzive kuti nepo 940 nm inoonekwa seye ziso pasi pemamiriro ezvinhu akajairika, kwenguva yakareba kana kuratidzwa kwakanyanya kune ino waveleng inogona kuchiri kukuvadza. Iyo International Electrotechnical Commission (IEC) yakaisa kuchengetedza zvinodiwa kuti uve nechokwadi chekushandisa kwakachengeteka kwe lasers uye zvimwe zvinowanikwa zvemahara radiation, kusanganisira infrared.
Maererano neIEC 608-12-16-16-16-16-16-16 Blass
Iyo IEC zviyero zvinotsanangudza miganhu yekuwisidzira, ichitsanangura iyo yakanyanya kubvumidzwa kuratidzwa (mPE) kune akasiyana mawlength uye duratidens. Iyi miganhu yakavakirwa pakutsvakisisa kwakawanda uye funga nezve mukana wezvose zviri zviviri zvinobaya uye Photochemical kukuvara kune ocular tishu.
Kuve nechokwadi chekuchengetedza kwemaziso, vagadziri vemidziyo inokoshesa 940 nm infrared mwenje, senge Ir Lecs uye laser diode, inofanira kuomerera kune aya ekuchengetedza zviyero. Ivo vanosanganisira yakakodzera kuchengetedzwa maitiro, senge bhebhi rakatsvuka, masimba masimba, uye mafirita emhepo, kuti aderedze njodzi yekukuvara kwemaziso.

Mukupedzisa, 940 NM infrared mwenje inowanzoonekwa seye ziso-yakachengeteka mumamiriro ezvinhu akajairika ekushanda. Kunyanya kuderera kwakawanda neocular tishu, kunyanya cornea, lens, uye retina, inoderedza njodzi yekukuvara. Nekudaro, kuomerera kune zvakachengetedzeka zviyero, senge izvo zvakagadziriswa neIEC, inokosha yekuita zvakachengeteka kushandisa uye kudzivirira chero chinogona kukuvadza chakabatana neyakareba kana kufumurwa kwakasimba kune iyi wavelength.
