Precision-molded PMMA acrylic delivers 92% light transmittance, ensuring efficient solar concentration and bright, clear optical projection. Available in 40mm to 100mm diameters with a focal length of 60-80mm, offering flexible options for DIY solar cookers, magnifiers, or lab setups. Ultra-thin 2mm profile with a smooth 0.3mm thread pitch (0.5mm for 100mm/120mm focal version) minimizes distortion and maximizes accuracy. Built to withstand temperatures from -40°C to +80°C, this lens resists yellowing and warping, making it reliable for outdoor or high-heat applications. Each package includes one round lens, ready to use for educational demonstrations, solar experiments, or as a replacement optical component.
