New discovery! A card-type magnifying glass with 3x magnification and high transparency.
◆ Astonishingly unprecedented, a one-of-a-kind latest design hybrid diffraction lens ◆ Conventional card-type magnifiers, known as "Fresnel lenses," have low magnification (about 1.5x to 2x) and feature a grooved surface, which leads to issues such as degradation from scratches and problems with dust and dirt. At Eschenbach, we utilized the diffraction of light to develop a thin lens that minimizes the visibility of scratches and dirt, offers high transparency, and provides higher magnification than traditional lenses. After over 20 years of research and development, we have successfully commercialized a groundbreaking, entirely new superior lens. 【Features】 ● By adopting the "diffraction principle," we achieved a thin lens with high transparency and high magnification that prevents scratches and dirt. ⇒ Utilizing the newly developed "diffractive aspheric lens," which incorporates cutting-edge technology. ● The lens automatically lights up when opened and turns off when stored. ⇒ The light source uses a newly developed flat-type "SMD-LED." ⇒ The power supply consists of button batteries (2025 x 2), allowing for approximately 5 hours of continuous illumination. ● Same size as a credit card, with a thickness of only 6mm. ● Ideal magnification (3x) for checking fine print and reading, making it perfect for portability.
