The lens utilizes fully multi-coated optical s and a 4-group, 4- lens construction, effectively reducing light reflection and refraction losses and improving light transmittance. This ensures sharp, detai, distortion- at 200x magnification. With its app- design, there's no need to download or install any software. Simply attach the lens to your ph's camera with a universal clip and start microscopic observation. The simple operation makes it easy for seniors, students, and professionals to use. Equipped with a universal clip and a large .8 aperture, it's with 98% of all phs. Whether you're looking for a single or dual-camera ph, the clip allows for precise attachment without worrying about model mismatches. It's widely suitable for laboratory work (sample observation), STEM education applications (student science experiments), jewelry authentication (texture/authenticity identification), health diagnostics (microscopic examination of skin and hair), art investigations (analyzing pigment layers in paintings), and outdoor adventures (microscopic exploration of plants and animals). lens meets multiple needs. Rechargeable via USB. 1 The lens body is made of plastic, which is light and resistant to wear and tear, and is not easily damaged by collisions.
