Peb IR Inks thiab Pens yog chav kawm tshiab ntawm kev ruaj ntseg heev inks . Cov no inks yog pom tsis tau tag nrho rau tib neeg lub qhov muag tsis tau pom tau los ntawm kev siv lub cuab yeej uas tuaj yeem pom hauv infrared ntau - xws li peb hloov kho koob yees duab thiab camcorders. Hauv qab 400nm yog qhov ntau ntawm ultraviolet thiab siab dua 700nm isthe infrared ntau.
Hauv qhov no, IR number case yog dab tsi?
IR ink uas yog pom tsis tau ntawm qhov muag liab qab tab sis thaum raug IR lub teeb tshwm li dub rau thiab IR lub koob yees duab. Cov tsos ntawm lub teeb, infrared lens yog tsaus, meej tus cwj mem (tsis muaj xim), uas nqus nyob rau hauv infrared.spectrumcolor, uas yog tov.
Tsis tas li ntawd, tus number case kev ruaj ntseg yog dab tsi? Kev ruaj ntseg inks muaj los tiv thaiv cov ntaub ntawv luam tawm nyob rau hauv txawv guises. Pom tsis pom Ink . Ib qho ntawm lawv feem ntau siv dav inks yog pom tsis pom ultraviolet thiab yuav tshwm sim thaum luam tawm nyob rau hauv lub teeb dub (lossis UV lightsource). Cov tus cwj mem tsis pom qhov muag (covert) undernormal teeb pom kev zoo.
Tib neeg kuj nug, dab tsi yog infrared xim?
Infrared hluav taws xob feem ntau yog siv los 'pom dhau' pleev xim txheej uas yog impenetrable rau tib neeg lub qhov muag. Nws hla dhau pleev xim kom txog thaum nws ncav cuag ib yam dab tsi uas absorbsit, los yog nws yog reflected rov qab mus rau lub koob yees duab. Cov pa roj carbon dub yog nqus tau zoo heev infrared hluav taws xob.
Koj puas tuaj yeem pom tsis pom tus cwj mem nrog tsom iav?
Ua tiav invisible ink qhov muag tsom iav uas pom tau los ntawm kev ua si daim npav kom meej meej thiab raug thaum koj siv invisible ink cim decks. Dab tsi ntxiv, koj ua tau siv kev twv txiaj tsom iav mus ntes pom tsis pom rau kev ua si phaib seb lwm tus neeg uas ua ntawv dag nrog magicmarked phaib.

Tshooj 3: Sawv thiab Caij Nplooj Ntoos Hlav Henry tuaj yeem tshawb nrhiav tag nrho tsib lub zog tshwj xeeb kom ua tiav txoj haujlwm no rau Twisted Alice. Tag nrho cov iav tshwj xeeb yog nyob rau hauv lub thawv iav, nyob random nyob ib ncig ntawm Qib K
Puas yog Canon Pixma mg3620 tuaj nrog number case?
Lub Canon Pixma MG3620 yog ib qho inkjetprinter tag nrho-hauv-ib lub tshuab luam ntawv nrog scan thiab luam cov haujlwm. Nws ua haujlwm nrog Windows thiab macOS. Lub tshuab luam ntawv ntau xim yuav tsum tau hloov thaum ib qho xim tag nrho. Lub tshuab luam ntawv tsis muaj qhov screen
Dab tsi yog qhov txawv ntawm thermal thiab infrared koob yees duab?
Cov koob yees duab cua sov siv hluav taws xob los ntawm thaj tsam deb infrared ntawm lub spectrum, thaum IR lub koob yees duab hmo ntuj pom kev siv lub teeb los ntawm ntau qhov ntau zaus ntawm thaj tsam infrared. Tab sis iav feem ntau opaque rau cov thermal imaging zaus, thiab silicon sensors tsis teb rau photons ntawm lub zog
Lub infrared illuminator ua dab tsi?
Infrared illuminator, los yog IR illuminator, yog ib lub cuab tam uas emits lub teeb nyob rau hauv lub infrared spectrum. Cov hluav taws xob infrared tsis pom ntawm tib neeg lub qhov muag, tab sis rau qhov pom kev hmo ntuj, IR illuminator ua haujlwm zoo li lub teeb nyem
Lub tshuab luam ntawv twg yog qhov ua tau zoo tshaj rau tus number case?
Ib qho ntawm cov inkjets ua tau zoo tshaj plaws yog OfficeJetPro 8210. Zoo li OfficeJet 6968, HP 8210 yog lwm lub tshuab luam ntawv inkjet uas siv cov tshuab luam ntawv zoo. Lub tshuab luam ntawv uas muaj tag nrho uas muaj 50% tus nqi qis dua ib nplooj ntawv dua li lub tshuab luam ntawv laser, raws li HP
