Laser Cwjmem Yuav Tsum Tsis Muab Xa Rau Li Cov Me Nyuam' s Hnub Khoom Plig!
Sijhawm yoov nyob rau lub sijhawm, thiab txog nrab lub caij ntuj sov, menyuam' Hnub Txhua xyoo los txog. Rau cov menyuam' s hnub so hnub so ntev, cov niam txiv tseem ua tub sab thiab tsis tuaj yeem ua dab tsi. Khoom plig dab tsi yuav tsum tau muab rau cov me nyuam? ntoo thaiv tsev? Me nyuam roj hmab ntxim hlub? Neeg hlau txias ...
Txawm li cas los xij, cov niam txiv yuav tsum tsis txhob nqa cov npauj npib li Cov Menyuam' hnub khoom xa tuaj rau koj cov menyuam.
Laser pointer qauv
Laser npiv, tseem hu ua laser taw tes, lub hnub qub pointer cwjmem, thiab lwm yam, yog ua tiav cov ntawv xa tawm. Cov paib taw qhia laser yog liab, xiav, ntsuab, thiab xiav-violet, thiab cov taw tes laser rau txhua xim tsis zoo ib yam. Cov paib pom tshwm sim xws li lub teeb liab (λ=650-660 nm, 635 nm), lub teeb ntsuab (λ=515-520 nm, 532 nm), lub teeb xiav (λ=445-450 nm), thiab lub teeb xiav (violet) (λ=405 nm). Lub hauv paus tseem ceeb ntawm cov laser pointer yog lub teeb laser. Hais ncaj qha, lub laser diode tej zaum yuav tsis muaj lub tswv yim, tab sis thaum nws los txog rau lub taub hau kho qhov muag hauv qhov kho qhov muag, nws yuav to taub zoo dua. Qhov tseeb, nyob rau hauv cov khoos phis tawm kho qhov muag tsav dav dav, lub tshuab hluav taws xob semiconductor laser diode yog ib qho tseem ceeb ntawm lub taub hau kho qhov muag, thiab nws feem ntau tau tsim los ntawm triple heterostructure ntawm AsAlGA ternary compound, uas yog qhov ze ntawm infrared semiconductor ntaus ntawv. Kev yoj hluav taws xob ntawm lub teeb ci yog 780 txog 820 nm, thiab lub zog ntsuas hluav taws xob feem ntau yog 3 txog 5 mW. Nyob rau hauv tas li ntawd, muaj kuj yog ib tug pom lub teeb (eg, liab) semiconductor laser diode uas yog tseem lug siv nyob rau hauv kho qhov muag drives thiab bar code txawj nyeem ntawv - koj yuav tau to taub nws raws li ib tug tshwj xeeb ntawm lub teeb emitting diode.
Txawm li cas los xij, nrog peb cov taw qhia laser thoob plaws, lub zog ntawm laser diodes siv yog ntau dua li lub taub hau fais fab ntawm lub kho qhov muag disc tsav, uas feem ntau tshaj 250mW. Lub teeb mem hluav taws xob ua kom pom los ntawm cov kws tshaj lij ntawm 3.15 tog tau siab txawm tias 1400mW. Laser cwj mem zog yog me me, tab sis 250mW tom qab tsom yog qhov txaus ntshai heev.
Txawm hais tias qhov tseeb lub zog ntawm lub laser diode siv nyob rau hauv lub laser pointer tsis siab (txawm tias siab li 1400mW, uas yog 1.4W), qhov kev phom sij yog qhov nws nthuav lub zog rau ib qho taw tes.
Cov Kws Pab Tswv Yim
Raws li portable cwj mem transmitter tsim nrog pom laser, lub pointer laser yuav ua rau puas tsuaj loj rau lub retina, macula, lossis txawm dig muag mus tas li nyob rau hauv lub qhov muag. Lub macula yog nyob rau hauv qhov chaw kho qhov muag ntawm tib neeg lub qhov muag thiab yog qhov chaw ua haujlwm ntawm qhov pom ntawm qhov muag, qhov tseem ceeb tshaj plaws ntawm kev pom tseeb. Thaum cov neeg zoo ntawm pom lub laser, laser yuav tsom ntsoov rau cov macula ua macular kev puas tsuaj, ces siv ib tug laser pointer yuav tsum tau ceev faj! Ntxiv mus, lasers feem ntau yog siv hauv cov tub rog thiab kev kho mob thiab lwm qhov chaw tshaj lij. Txawm hais tias lawv yog cov khoom siv laser uas ua tau raws li lub teb chaws tus qauv, kev tiv tauj ntau dhau los yog kev siv tsis saib xyuas yuav cuam tshuam rau lub zeem muag. Tus kws sau ntawv tau tawm tswv yim tias cov neeg zoo tib yam hauv thaj chaw uas tsis yog kws tshaj lij, tshwj xeeb tshaj yog cov menyuam yaus, tsis txhob kov cov khoom lag luam laser.
Los Ntawm Txoj Kev
Yuav ua li cas hom ntawm khoom plig no yog tsim rau cov me nyuam?
Nyob rau hauv lub sau' s lub tswv yim, hais txog cov niam txiv yuav tsum yog tus tshaj plaws khoom plig rau cov me nyuam.Yuav ua li cas koj xav hais tias? ^ _ ^
