V-Dahaarka leh Laser-ka-ilaalinta Daaqadaha

Daaqadaha indhaha ayaa bixiya ilaalinta inta u dhaxaysa nidaamka indhaha ama elektarooniga xasaasiga ah iyo deegaanka ka baxsan. Waa muhiim in la doorto daaqad gudbisa mawjadaha loo isticmaalo nidaamka. Intaa waxaa dheer maaddada substrate-ka waa inay awood u leedahay inay u adkeysato xaaladaha deegaanka ee codsiga. Daaqadaha waxaa lagu bixiyaa tiro balaadhan oo ah substrates, cabbirro iyo dhumucyo si ay u daboolaan baahi kasta oo codsi ah.

Paralight Optics waxay bixisaa daaqadaha laydhka leysarka ee V-dahaarka leh ee codsiyada kuwaas oo u baahan ilaalinta wax soo saarka laysarka iyada oo la yareynayo iftiinka iyo milicsiga. Dhinac kasta oo indhaha ka mid ah waxa uu leeyahay daahan AR ah kaas oo udub dhexaad u ah mawjada laser caadiga ah. Daaqadahani waxay soo bandhigaan heerar burbur sare leh (> 15J/cm2), waxaa loo adeegsadaa laysarka hortooda si loo farsameeyo agabka si looga ilaaliyo laysarka indhaha dhibco kulul. Waxaan sidoo kale bixinaa daaqadaha laysarka ee goglan.

Dahaarka V waa lakabyo badan, ka-hortagga, dahaarka khafiifka ah ee korontada ku shaqeeya oo loogu talagalay in lagu gaaro milicsiga ugu yar ee xadhig cidhiidhi ah oo hirarka dhererka ah. Milicsiga ayaa si degdeg ah uga kaca labada dhinac ee kan ugu yar, taasoo siinaysa qalooca milicsiga qaab "V". Marka la barbar dhigo dahaarka ballaadhan ee AR, dahaarka V-dahaarka waxay ku gaadhaan milicsi hoose marka loo eego baaxadda xajmiyeedka cidhiidhiga ah marka loo isticmaalo AOI-ga la cayimay. Fadlan hubi garaafka soo socda oo muujinaya ku-tiirsanaanta xagal dahaarka tixraacyadaada.

Garaafyada

Dahaarka AR ee daaqadaha laysarka waxaa si gaar ah loogu talagalay in lagu isticmaalo hirarka dhererka laser caadiga ah waxayna bixiyaan Ravg<0.5% in ka badan cabbirkooda dhererka mawjadaha iyo AOI = 0° ± 5°.
Jaantuska midig wuxuu muujinayaa sida hal daahan oo gaar ah uu caadi ahaan ugu shaqeeyo substrate-ka silica UV-ga leh ee xaglo kala duwan.
Macluumaad dheeraad ah oo ku saabsan dahaarka kale ee AR sida 400 - 700 nm, 523 - 532 nm, ama 610 - 860 nm, 1047 - 1064 nm ee N-BK7 ama kala duwanaanshaha hirarka dhererka 261 - 266 nm, 350 - 4 -1080 nm ee silica dabaysha UV, fadlan nala soo xiriir wixii faahfaahin ah.
