Abstract

본 발명은 반사체상의 반사 표면 층으로서 복합 반사율 증대층을 가지는 반사기에 관계하는 것으로 상기 복합층은 반사체에 면하는 알루미늄층, 반사될 광선을 향하며 굴절 계수 n2를 가진 외부층인 HI-층, 및 n2보다 작은 굴절 계수 n1을 가진 중간 알루미늄 산화물층인 LI-층으로 된 샌드위치 구조를 가진다. LI-층은 알루미늄층의 양극 산화에 의해 생성되며 유전상수 ε가 20℃에서 6 내지 10.5인 투명하고 구멍이 없는 장벽층이며, LI-층의 광학적 층두께 dopt.1와 HI-층의 광학적 층두께 dopt.2은 다음과 같다.
dopt.1=di·ni=li·λ/4±10nm, i=1,2
여기서, d1는 LI-층의 두께를 nm단위로 나타내며 d2는 HI-층의 두께(nm)이며 λ는 반사기 표면에 입사한 빛의 평균 파장(nm)이며 l1, l2는 홀수이다. 이 반사기는 적외선용 반사기 또는 기술적 조명용 램프, 특히 주광등(晝光登)으로 적합하다.
