Focal Length (mm) = -450
Size (mm) : Ø300
Pitch (mm) : 0.5
Thickness (mm) : 2
Material : PMMA
Type : Concave , Minus focus
◈ Efficiency and F number
From F1.2, the efficency is dramatically droped. It shows there is a certain ratio between focal length of fresnel and diameter of lens.
Bigger size Lens is not always the answer.
◈ Comparing transmittance of SOG(Silicone On Glass) and PMMA
Our Optical PMMA has higher transmitive than glass, which is 92~95%, and absorption in visual ray is almost 0%
