Cov kev teeb pom kev tseem ceeb ntawm cov laser pointer yog lub teeb laser. Nws tsim cov nqaj hluav taws xob nrog ib lub yoj ntawm txog 808 nm, uas dhau ntawm qhov lo ntsiab muag, tom qab ntawd nkag mus rau kev siv lead ua, uas yog raws li neodymium, yttrium, vanadium oxides. Hauv qhov siv lead ua, cov duab ci hloov mus ua hluav taws xob nrog qhov ntev ntawm 1064 nm. Ntxiv mus, tus kwj kis tau ntxiv nthwv cua ntawm 532-670 nm. Txav dhau qhov dhau ntawm qhov lim lim infrared, cov kwj dej sau hauv qhov nqaj los ntawm lub lens.
Cov Lus Qhia
Kauj ruam 1
Txhawm rau ua lub laser pointer nrog koj tus kheej txhais tes, nqa daim DVD sau ntawv tsis zoo. Yog tias koj muaj kev xaiv, mus rau qhov siab nrawm dua vim tias nws muaj lub zog dua laser. Npaj cov seem ntawm cov menyuam yaus pheej yig lub laser pointer, nws cov khoom siv kho qhov muag. Rau tib lub hom phiaj, koj tuaj yeem siv lub teeb nyem yooj yim ntawm Suav. Yuav 100 microfarad capacitor - 16 volts thiab 10 picofarad ceramic disk capacitor, microcircuit, tus tswj hluav taws xob KR 1158 EH 3V.
Kauj ruam 2
Tshem tawm cov khoom siv kho qhov muag tawm ntawm lub DVD tsav. Hauv nws koj yuav pom ob lub laser diodes. Ib qho ntawm lawv yog infrared, nws sau thiab nyeem CDs, thiab lub thib ob yog DVD. Koj xav tau daim DVD laser diode. Maj mam qhwv txoj xov nyias nyob ib ncig ntawm ob txhais ceg kom tiv thaiv hluav taws xob zoo li qub los ntawm ua kom nws.
Kauj ruam 3
Nrhav peb qhov ua peb sab nraub qaum ntawm lub laser diode. Thawj tus yog tawm tswv yim rau +2, 6 - 2, 8 V. Tus lej thib ob yog rho tawm ntawm qhov ntsuas hluav taws xob ib yam. Qhov thib peb yog tsis muaj feem.
Kauj ruam 4
Sau ua ke daim duab. Muag rau qhov tsis muaj-qhov muaj zog rau lub laser diode. Tam sim no tshem cov hlau los ntawm nws ob txhais ceg. Solder polarized capacitor thiab qhov ntsuas hluav taws xob qhov twg tus thawj tus pin yog qhov tso zis, qhov thib ob yog tshwm sim, thiab tus thib peb yog kev tawm tswv yim. Nco ntsoov qhov zoo polarity ntawm qhov voltage thiaj li tsis ua kev puas tsuaj rau Circuit Court.
Tam sim no muab tso ua ke stabilizer nrog ob lub twj tso kua mis, ib lub pob los ntawm cov xov tooj cua uas muab pov tseg, roj teeb, thiab lub qhov muag pom ntawm tus menyuam lub laser pointer.
Kauj ruam 5
Yog tias koj txiav txim siab siv lub lens los ntawm DVD tsav, nco ntsoov tias nws muaj lub ntsej muag luv luv, yog li koj yuav tsum teeb tsa lub caij nplooj ntoo hlav ntxiv uas yuav nias lub lens ntau nruj ntawm lub teeb diode.
