Title:
SELECTED WAVELENGTH REFLECTOR
Document Type and Number:
Japanese Patent JP2023133313
Kind Code:
A
Abstract:
To provide a selected wavelength reflector which has high transmittance at a wavelength which is not a wavelength for reflection and can optimize a selected wavelength highly accurately.SOLUTION: The present invention is formed in such a manner that a plurality of unit patterns 13 each having at least one metal structure 12 is regularly arranged vertically and horizontally along a surface of the base body 11 in the surface of a translucent base body 11. The unit pattern 13 is shaped so that the metal structure 12 is in the shape of + when is seen from a vertical direction with respect to the surface of the base body 11. When a width of a vertical line and a horizontal line of the + shape is denoted by w(nm) and a length of the vertical line and the horizontal line is denoted by l(nm), and a length of one side of the unit pattern 13 is denoted by Λ(nm), relations of 240≤l≤370, 30≤w≤90, and 360≤Λ≤450 are satisfied.SELECTED DRAWING: Figure 1
