摘要 | An optical component emits or transmits laser light of a wavelength of 460 nm or less. A first coating (A) formed from a dielectric film like SiO2 is applied upon at least a part of the surface thereof as an AR coating, and a second coating (B) formed from a dielectric film containing a noble metal or platinum group element is applied upon the first coating (A) to prevent contamination of the surface of the optical component. A laser diode (10) in a housing (70) with a window (20) may have said contamination preventing coating (B) on the light emitting surface and the outside of the window (20). |
其他摘要 | 光学部件发射或透射波长为460nm或更短的激光。由SiO 2等电介质膜形成的第一涂层(A)作为AR涂层涂布在其表面的至少一部分上,由含有贵金属或铂族元素的电介质膜形成的第二涂层(B)是施加在第一涂层(A)上以防止污染光学元件的表面。具有窗口(20)的壳体(70)中的激光二极管(10)可以在发光表面和窗口(20)的外部具有所述防污涂层(B)。 |
