EXPLORATORY PREPARATION OF FOILS STRONGLY COLORED IN THE 1 - 6 MICRON REGION OF THE INFRARED

Abstract

A search was made for a material approximating the following combination of qualities: A strongly colored reflectivity, specular or diffuse, in the near IR conforming closely to the schedule: > 5 micron 1.0 reflec tivity; 4 micron, 0.9; 3 micron, 0.8; 2.5 micron, 0.7; 2 micron, 0.45; 1.5 micron, 0.3; 1 micron, 0.2; <0.8 micron, <0.1. Minimum absorption at all wavelengths. Minimum weight per unit area of reflecting surface, in the order of l gm/sq meter (5000 sq. ft. /lb); this is the weight of a plastic foil about 1 micron thick. Easy dispersal, from storage in a compact form, into separated airborne flakes or bubbles, large enough (>30 micron diameter) that diffraction effects will not distort the color, yet small enough to resist deformation by ordinary air turbulence. Cost, in the storage form, not exceeding $. 02/sq ft.
