🔍 Product Overview
This 40x high-definition folding magnifier features an all-metal body and high-definition optical lenses, combining dual LED white light illumination with UV light for counterfeit detection. The 40x magnification falls within the ideal range for handheld inspection—it clearly reveals inclusions inside jewelry and gemstones, bubbles and patina layers on antique glazes, and wear marks on coin edges, without causing an overly narrow field of view or loss of focus due to hand tremors caused by excessive magnification.
The folding design is compact and portable; when folded, it’s about the size of a credit card and fits easily into a pocket or tool kit. Whether you’re a jewelry appraiser, an antique collector, an electronics repair engineer, or simply need to verify banknotes or appraise stamps, it will serve as your reliable “second set of eyes.”
✨ Key Selling Points
🔹 40x high-definition magnification reveals every minute detail
Features a 25mm large-aperture high-definition optical lens that provides a clear, distortion-free field of view. Diamond girdle dimensions (as small as 0.1–0.2 mm in height), fibrous inclusions inside jadeite, and solder marks on karat gold joints—microscopic details that are difficult to capture with the naked eye become clearly visible at 40x magnification.
🔹 LED White Light + UV Light: Dual Light Sources for Any Scenario
Dual LED white light: Provides bright, even illumination even in dark or low-light environments, allowing you to clearly see the true colors and textures of objects.
UV light: Can be used for anti-counterfeiting verification of banknotes, passports, credit cards, and more; in jewelry appraisal, UV light can trigger fluorescence reactions, identify repair marks, and verify the authenticity of materials—known in professional circles as the three essential elements of “light, magnification, and stability.”
🔹 All-Metal Body, Rugged and Durable
Made of high-quality aluminum alloy, it feels solid in the hand and is drop-resistant and wear-resistant—nothing like a cheap plastic casing. The metal casing, combined with a precision folding mechanism, ensures smooth opening and closing, a secure lock, and no loosening even with long-term use.
🔹 Portable and Foldable—Carry It Anywhere
When folded, it measures just 58Ă—30Ă—27 mm, easily fitting into a pocket, handbag, or toolbox. Simply unfold it for use and fold it back up for storage, ensuring the lenses are fully protected.
🔹 Ready to Use Right Out of the Box—Batteries Included
Equipped with 3 built-in LR1130 button cells, which are pre-installed before shipping, so it’s ready to use the moment you open the box. Batteries are easy to replace and offer long-lasting power.
🎯 Applications
Jewelry and Gemstone Appraisal: Examine internal inclusions in gemstones, acid-etched patterns on jadeite (a characteristic of “B-grade” jade), diamond girdle marks, and the structural orientation of jade
Antiques and Art Collection: Inspect bubbles in porcelain glaze, the layering of patina, the direction of engravings, and the paper fibers in calligraphy and paintings
Coin and Stamp Appraisal: Identifying the reeded edges of silver dollars, pressure marks on machine-struck coins, the precision of stamp perforations, and printing halftone dots
Electronic Device Repair: Inspecting solder joints on PCBs, chip pins, and wear on gold contacts
Currency Authentication: Quickly verifying the authenticity of banknotes, passports, and credit cards under UV light
Textile/Printed Material Inspection: Observing fabric yarn density and the edges of printed halftone dots

âť“ Frequently Asked Questions (FAQ)
Q: Is 40x magnification sufficient? Will it be too high, making it difficult to see clearly?
A: 40x is considered the ideal magnification for handheld inspection—it clearly reveals microscopic details (such as diamond girdle marks and jade inclusions) without causing a narrow field of view or loss of focus due to hand tremors. Combined with a 25mm large-aperture lens, it provides a comfortable viewing experience.
Q: Can the LED light and UV light be turned on at the same time?
A: The product features independent switches, allowing you to turn on the LED white light or UV light separately as needed, or use them simultaneously.
Q: How long do the batteries last? How do I replace them?
A: The product uses 3 LR1130 button cells, which are pre-installed before shipment. The battery compartment is designed for easy replacement, and the battery life is long under normal use.
Q: Are the lenses prone to scratches?
A: The lenses are made of high-definition optical glass. Thanks to the folding design, the lenses are protected by the metal casing when the device is closed. Simply avoid contact with hard objects during daily use.
