Abstract

PURPOSE:To obtain a condensing surface of a square shape with a squre light- condensing member by forming the four parts of a right-angled triangle shape created by the diagonal lines of an optical member of a square outside shape into a Fresnel shape, and flattening the bottom surface. CONSTITUTION:The four parts of a right-angled triangle shape created by the diagonal lines of an org. glass material of a square outside shape are formed into a Fresnel lens shape, and the bottom surface is flattened. This lens is formed by heating the org. glass material to polymerize by using molds. Solar heat is utilized efficiently by using this.
