N-BK7 (CDGM H-K9L)
Lenses Plano-Convex

Muraayadaha Plano-convex (PCX) waxay leeyihiin dhumuc qumman oo togan waxaana loo isticmaali karaa in diiradda la saaro iftiinka isku-dhafka ah, in la isku duwo isha dhibicda, ama si loo yareeyo xagasha kala-duwanaanshaha ilaha kala duwan. Marka tayada sawirku aanay muhiim ahayn, muraayadaha plano-convex waxa kale oo loo isticmaali karaa beddelka labajibbaaran achromatic. Si loo yareeyo horu dhigga aberration spherical, isha ilayska ee isku xidhan waa in ay ku dhacdo dusha qaloocan ee lenska marka diirada la saarayo iyo ilayska dhibicda waa in uu dhacaa dusha sare marka la isku dhaco.

Tusaalaha Codsiyada Codsiyada OEM

Lens kasta oo N-BK7 ah waxaa lagu bixin karaa 532/1064 nm, 633 nm, ama 780 nm leys line V-coating. Dahaarka V-du waa lakabyo badan, ka-hortagga, daahan-filim khafiif ah oo dielectric ah oo loogu talagalay in lagu gaaro milicsiga ugu yar ee xadhig cidhiidhi ah oo hirarka dhererka ah. Milicsigu si degdeg ah ayuu uga kacaa labada dhinac ee kan ugu yar, isagoo siinaya qalooca milicsiga qaabka "V", sida ka muuqata qaab-dhismeedka soo socda. Macluumaad dheeraad ah oo ku saabsan dahaarka kale ee AR sida kala duwanaanshaha hirarka dhererka ee 350 - 700 nm, 400 - 1100 nm, 650 - 1050 nm, ama 1050 - 1700nm, fadlan nala soo xiriir wixii faahfaahin ah.

Paralight Optics waxay bixisaa N-BK7 (CDGM H-K9L) lenses Plano-Convex oo leh ikhtiyaaro ah kuwa aan dahaarka lahayn ama kuwa ka-hortagga milicsiga (AR), kaas oo yareynaya cadadka iftiinka ee ka muuqda dusha kasta oo muraayadda. Maadaama ku dhawaad 4% ee iftiinka dhacdada uu ka muuqdo dusha kasta oo ka mid ah substrate-ka aan la daboolin, adeegsiga dahaarkayada lakabyada badan ee AR waxay hagaajiyaan gudbinta, taas oo muhiim u ah codsiyada iftiinka hooseeya, waxayna ka hortagtaa saameynta aan loo baahnayn (tusaale, sawirada rooxaanta) la xidhiidha milicsiga badan. Lahaanshaha indho-indheynta leh dahaarka AR ee loo habeeyay cabbirka muuqaalka ah ee 350 – 700 nm, 400 – 1100 nm, 650 – 1050 nm, 1050 – 1700 nm, 1650 – 2100 nm oo lagu kaydiyay labada dusha sare. Dahaarkani wuxuu si weyn u yareynayaa celceliska milicsiga substrate-ka in ka yar 0.5% (Ravg <1.0% ee kala duwanaanshaha 0.4 - 1.1 μm iyo 1.65 - 2.1 μm) dusha sare, taasoo keenaysa isku-gudbinta celceliska sare ee dhammaan noocyada daahan AR ee xaglaha dhacdooyinka (AOI) inta u dhaxaysa 0° iyo 30° (0.5 NA). Qalabka indhaha ee loogu talagalay in loo isticmaalo xaglaha dhacdada, tixgeli isticmaalka dahaarka gaarka ah ee lagu hagaajiyay xagal 45° ah; daahan caadadu waxay wax ku ool u tahay 25 ° ilaa 52 °. Dahaarka Broadband waxay leeyihiin nuugista caadiga ah ee 0.25%. Ka eeg jaantusyada soo socda tixraacyadaada.
