O tioata N-BK7 taʻitasi e mafai ona ofoina atu i le 532/1064 nm, 633 nm, poʻo le 780 nm leisa laina V-coating. O le V-coating o se multilayer, anti-reflective, dielectric thin-film coating ua fuafuaina e maua ai sina faʻataʻitaʻiga i luga o se vaega vaapiapi o galu umi. E vave ona oso a'e le ata i itu uma e lua o lenei pito maualalo, e maua ai le ata o le ata o se foliga "V", e pei ona faaalia i ata faatino nei. Mo nisi faʻamatalaga i isi AR coatings e pei ole galu umi laina ole 350 - 700 nm, 400 - 1100 nm, 650 - 1050 nm, poʻo le 1050 - 1700nm, faʻamolemole faʻafesoʻotaʻi matou mo faʻamatalaga.
O le Paralight Optics e ofoina atu tioata N-BK7 (CDGM H-K9L) Plano-Convex ma filifiliga e le'i fa'apipi'iina po'o a tatou fa'alavalava fa'aantireflection (AR), e fa'aitiitia ai le aofa'i o le malamalama o lo'o atagia mai mata ta'itasi o le tioata. Talu ai e tusa ma le 4% o le malamalama faʻafuaseʻi o loʻo atagia i luga o mea taʻitasi o se mea e leʻi faʻapipiʻiina, o le faʻaogaina o la tatou faʻapipiʻi faʻapipiʻi AR e faʻaleleia atili ai le felauaiga, lea e taua i faʻaoga maualalo, ma puipuia ai aʻafiaga e le manaʻomia (faʻataʻitaʻiga, ata ghost) fa'atasi ma le tele o mafaufauga. O le i ai o optics ma AR coatings optimized mo le spectral range of 350 – 700 nm, 400 – 1100 nm, 650 – 1050 nm, 1050 – 1700 nm, 1650 – 2100 nm ua teuina i luga o luga uma e lua. O lenei faʻapipiʻi e faʻaitiitia ai le averesi o le faʻataʻitaʻiga o le substrate i lalo ifo o le 0.5% (Ravg <1.0% mo laina ole 0.4 - 1.1 μm ma le 1.65 - 2.1 μm) i luga ole laiga, e maua ai le maualuga o le felauaiga i luga ole laiga atoa ole AR mo tulimanu ole fa'alavelave (AOI) i le va o le 0° ma le 30° (0.5 NA). Mo optics e fa'amoemoe e fa'aoga i tulimanu tetele fa'alavelave, mafaufau e fa'aaoga se fa'apipi'i fa'aaganu'u e fa'asilisiliina ile 45° angle o fa'alavelave; o lenei faʻapipiʻi masani e aoga mai le 25 ° i le 52 °. O lapisi lautele e iai le faʻaogaina masani o le 0.25%. Siaki kalafi o lo'o mulimuli mai mo au fa'amatalaga.
