P578.61 Tuubbada Baaraha Ultraviolet ee loo adeegsaday Qra2/Qra10/Qra53/Qra55

Sharaxaad Gaaban:

waa tuubbada sheega UV ee gubiyaasha.Qalabka ultraviolet-ka ayaa inta badan loo isticmaalaa in lagu ogaado xaaladda ololka ee gubiyaha si loo hubiyo shaqada caadiga ah ee gubta.

Hordhac koobanSawirka ultraviolet:

Sawirka ultraviolet waa nooc ka mid ah tuubbada ogaanshaha ultraviolet oo leh saameyn koronto.Photocell noocan oo kale ah waxay isticmaashaa cathode si ay u dhaliso sawir-qaadista, photoelectrons waxay u guuraan anode-ka hoos yimaada ficilka korontada, iyo ionization waxay dhacdaa sababtoo ah isku dhafka gaaska ee tuubada inta lagu jiro koorsada ionization;electrons cusub iyo photoelectrons sameeyay habka ionization labadaba helay anode ah, halka ions togan waxaa helay cathode ee jihada ka soo horjeeda.Sidaa darteed, sawirka ku jira wareegga anode-ka ayaa dhowr jeer ka weyn kan ku jira sawirka vacuum.Unugyada sawirada ultraviolet leh birta sawir-qaadista iyo saamaynta gaasku waxay ku ogaan karaan shucaaca ultraviolet inta u dhaxaysa 185-300mm waxayna dhalin karaan sawir.

Waa dareen la'aan shucaaca ka baxsan gobolkan spectral, sida iftiinka qorraxda ee muuqda iyo ilaha iftiinka gudaha.Markaa muhiim ma aha in la isticmaalo gaashaanka iftiinka muuqda sida aaladaha kale ee semiconductor, markaa way ku habboon tahay in la isticmaalo.
Sawirka ultraviolet wuxuu ogaan karaa shucaaca ultraviolet daciif ah.Waxaa loo isticmaali karaa saliidda kululeeyaha, ilaalinta gaaska, alaarmiga dabka, nidaamka korantada ee ilaalinta hillaaca la socodka transformerka aan la ilaalin, iwm.
