<div class="div-os-obd"></div><div class="div-os-obd"><p class="p-os-obd">This high-precision Fresnel lens is an efficient optical component designed for superior light concentration and versatile magnification. Suitable for focusing light in solar heating experiments and small DIY solar projects, its high light transmittance and efficient focusing ability concentrate sunlight to generate heat. Furthermore, this lens is a perfect tool for physics teaching; it can also be used in lighting glass, artwork, projectors, projection lamps, photographic equipment</p></div><div class="div-os-obd"><p class="p-os-obd"><br class="div-os-obd"></p></div><div class="div-os-obd"><p class="p-os-obd"><strong>Advantages:</strong></p></div><div class="div-os-obd"><p class="p-os-obd">This Fresnel lens is made of optical-grade acrylic material, offering high precision, high light focusing efficiency, and high transparency, ensuring light passes through with minimal loss while reducing optical distortion. The lens is small and lightweight, making it easy to carry and store.</p></div><div class="div-os-obd"><p class="p-os-obd"><br class="div-os-obd"></p></div><div class="div-os-obd"><p class="p-os-obd"><strong>Instruction:</strong></p></div><div class="div-os-obd"><p class="p-os-obd">Using a Fresnel lens is very simple. When conducting solar heating experiments, point the lens at the sun and adjust the angle to concentrate sunlight onto the desired area to the maximum extent. When using the lens for magnification, ensure the object is within the lens's focal length for a clear image. For cleaning, the lens can be easily cleaned with a soft, dry cloth to maintain its transparency and optical performance.</p></div><div class="div-os-obd"><p class="p-os-obd"><br class="div-os-obd"></p></div><div class="div-os-obd"><p class="p-os-obd"><strong>NOTES:</strong></p></div><div class="div-os-obd"><p class="p-os-obd">Avoid touching the lens surface with your fingers to prevent affecting light transmission. When not in use, store the lens in a cool, dry place, away from direct sunlight to prevent deformation or damage.</p></div><div class="div-os-obd"></div>
