Anti reflective film-a hnathawh dan tur (working principle) .
Anti Reflective Film, Anti Reflective Film tia hriat pawh hi lens, prism, leh plane mirror ang chi optical lens chunglama reflected light tihtlem emaw tihbo emaw nan an hmang ber a ni. A hnathawh dan chu êng inthlak danglamna leh a lan chhuahnaah a innghat a ni. A hnuaia tarlan te hi i tan chipchiar taka inhriattirna a ni:

Reflection leh Interference Phenomena of Light .
Anti reflective film-a light irradiate a nih chuan, a ṭhen chu film sir lehlamah a rawn lang leh ang a, heng reflected light column pahnih hian a rawn inrawlh ang. Film thickness hian condition thenkhat a tlin chuan reflected light wave column pahnih chu a inzawm tlat ang a, a tichhe thei bawk ang. Entirnan, film thickness a remchan hunah chuan film surface pahnih a reflected light inkar distance danglamna chu wavelength chanve nen a inang chiah a, chutiang chuan an in cancel chhuak ta a ni. Hei hian êng hlohna nasa takin a ti tlem a, êng thawn chhuah nasatzia a tichak bawk.

Film thickness leh wavelength inzawmna .
Anti reflective film thickness hi a tlangpuiin one-quarter wavelength a ni. Theory-ah chuan 0.5 wavelength optical path difference odd multiple chuan reflected light interference a tichak lo thei a, mahse film thickness a san chuan transmission chu a chak lo ang. Chuvangin, a let 0.25 zetin wavelength hi a tlangpuiin thlan a ni. Entirna atan red light hi la ila, anti reflection film-a red light wavelength hmun li a\\anga hmun khat nen a thickness chu a tlukpui a nih chuan, he film sir lehlamah hian red light reflect back chu a rawn inrawlh ang a, a cancel out ang.
