Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, an ultraviolet-visible-infrared full-band absorber consists of a substrate 1, several layers of ultraviolet-visible-infrared full-band anti-reflection film systems 2 above the substrate, and several layers of ultraviolet-visible-infrared band absorbing film systems below the substrate .

[0031] The material of substrate 1 is made of medium and far infrared absorbing materials, such as K9, fused silica, float glass and other glass materials, or plexiglass (acrylic, PMMA, polymethyl methacrylate, etc.), CR-39 (polypropylene-based di Glycol carbonate), PC (polyethylene carbonate), PS (styrene) and other organic polymer materials.

[0032] The UV-visible-infrared full-band anti-reflection film system 2 is composed of alternately stacked materials with similar refractive indices in the ultraviolet-visible-near-infrared band but with a ...

Abstract

The invention discloses an ultraviolet-visible-infrared full-band absorber. The absorber comprises a substrate with a middle and far infrared band absorption function; an ultraviolet-visible-infrared full-wave band antireflection film system which is arranged on one side of the substrate; and an ultraviolet-visible-near infrared band absorption film system which is arranged on the other side of the substrate. The invention also discloses a preparation method of the ultraviolet-visible-infrared full-wave band absorber. The ultraviolet-visible-infrared full-wave-band absorber can achieve full-wave-band efficient absorption of ultraviolet, visible and infrared wave bands, and is simple in structure, low in cost and suitable for large-area batch production.

Description

technical field [0001] The invention belongs to the fields of stray light elimination, space detection, imaging, light-to-heat conversion, electromagnetic absorption, etc., and specifically relates to an ultra-broadband absorber in the full range of ultraviolet-visible-infrared. Background technique [0002] Although the research on broadband absorbers has been carried out for many years, most of the research is limited to the visible-near-infrared band, and few involve the full range of ultraviolet-visible-infrared. In fact, carbon nanotubes or titanium oxide nanotubes and their derivatives have excellent absorption properties in the full range of ultraviolet-visible-infrared, but their fragile mechanical properties and unsatisfactory thermal / chemical stability seriously restrict their widespread use. and multi-field applications. The ultraviolet-visible-infrared full-band absorber has a huge demand in the fields of stray light elimination, light-to-heat conversion, electr...
