NEAR IR BEAM SHADE AND NEAR IR BEAM SHADING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a near IR beam shade which is colorless and high in visible ray transmittivity and transparency, efficiently shades the near IR beam which is the heat beam in sunlight and the electromagnetic waves of near IR laser beams, and has scratch resistance, and also provide a near IR beam shading structure using it. SOLUTION: The near IR beam shade contains 1.0-3.5 g/m2of antimony doped tin oxide and 0.01-0.1 g/m2of a perylene series compound having the maximum absorption wavelength at 770-1500 nm per unit area, and is made by coating. It has a scratch resistant layer on the surface, and the near IR beam shading structure has the near IR beam shade on the base. COPYRIGHT: (C)2008,JPO&INPIT
