Peegeldusvastane kate

/
19.1.2019

Heaks nägemiseks on vajalik, et võimalikult palju valgust läheks klaasist läbi ja jõuaks silma. Selleks lisatakse klaasidele peegeldusvastane kate, mis vähendab nägemist häirivaid peegeldusi ja aitab kaasa paremale nägemisele. Tavaline prillilääts (prilliklaas) peegeldab valgust umbes 8%, mille tulemusena ei jõua peegelduste tõttu läbi prilliklaasi kogu valgus ja informatsioon silmani. Kui tegemist on õhukese klaasiga võib valgusekadu ulatuda 20%-ni.

Peegeldusest tingitud valguskadusid hoitakse ära prilliklaasi optilistele pinnale kantud peegeldusvastase  AR (antireflection) pinnakattega, mis vähendab peegeldusi 1%-ni. Lisaks klaasi optilisele paranemisele on tähtis ka esteetiline efekt – prilliklaas on pea märkamatu, jättes prillidest kergema ja õhulisema mulje.
