Fresnel lens with square concentric circles on the front and smooth surface on the back, regular thickness of 2 mm, edge and center thickness the same (non-convex lens)(non-glass) Fresnel lens and convex lens are the same in function, but the shape is completely different, please pay attention to the distinction. The measured focusing temperature was 636.8 F at 86 F outdoors The focal length spot has no astigmatism and the spot is uniform Fresnel lens with square concentric circles on the front and smooth surface on the back Focal length is the linear light focused through the lens to form a spot, when the spot is the smallest, the linear distance between the center of the lens and the spot is the focal length\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Six Seasons\u003c\/p\u003e\n\u003cp\u003elarge 300x300mm, starter, fresnel, magnifiying sheet, solar oven, scientific, death ray, ray physics, science, focal, industrial scientific, 300mm Industrial \u0026amp; Scientific Science Education\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✓ 11.8111.81in (300300mm) square Fresnel lens, 300mm focal length, 2mm ultra-slim profile.
