It achieves a "distortion-free image" with no blind spots at the lens periphery and eliminates spherical aberration, maintaining consistent sharpness across the entire image. **Premium Suede Lens Cloth [Taiwan Exclusive]** Included with this product is a specially selected, double-sided brushed suede lens cloth, made in Taiwan. It effortlessly removes fingerprints, smudges, and other marks from the lens. The cloth is washable and reusable. **How to Use** 1. Position yourself facing forward. Rest the hand holding the jeweler's loupe gently against your cheekbone for stability. 2. With your other hand, use tweezers or your fingers to hold the object, resting your hand underneath on top of the hand holding the loupe. 3. Slowly bring the object closer to the loupe until it is at the focal point, where the sharpest image will appear. 4. Gradually move your head forward, shortening the eye relief, to achieve the optimal field of view. 5. Beginners often close the other eye while observing. Once accustomed to the viewing method, try opening the other eye, focusing solely with the observing eye. This can relax the muscles around the closed eye, allowing for longer viewing sessions. https://www.hwatang.com.tw/uploads/product/content/1afb580eb6cd6f4596c0d546443917fd.jpg **Precautions** * Do not place the loupe in direct sunlight while the lens is exposed, as this may cause a fire hazard. * The LOGO side of this product is the front; orient it towards your eye. The back side should face the object being observed for optimal imaging. * The focal length (working distance) and eye relief stated in the specifications are based on actual test results, but may vary slightly depending on individual vision conditions. * When cleaning the lens, gently wipe in a single direction with a clean cloth. Rubbing in circles or with excessive force may scratch the lens. **Product Specifications** Original Part Number: 117610 Magnification: 10x Lens Diameter: 21mm Lens Material: German-Made Optical Glass Lens Design: Aplanatic Parfocal Aspheric Design Body Material: Metal Focal Length: 16mm Eye Relief: 55mm Dimensions: 43-72 (L) x 28 (W) x 20 (D) mm Weight: 46g Origin: Germany **Brand Introduction** https://www.hwatang.com.tw/uploads/editor/Eschenbach/eschenbach-logo2-M4.jpg?1501828202782 German Eschenbach Optik was founded in 1913 and is a leading global manufacturer of vision aids.
