| 説明 | 2 layers of foamboard, foil in-between, backside covered with scrap fleece as an anti-reflective (and edges of aperture painted flat black as well). The sunward-face (not visible here) is untouched plain white foamboard, I figured that would help reject unwanted heat.The small donut allows a further reduction, down to the size of a US dime. |
