20x Ultra-small binocular jewelry microscope【JH301】

**Hamlet Optical Series Pocket Microscope** **20x Ultra Small Binocular Jewelry Microscope #JH301** **Product Introduction** The brilliant colors of jewelry and jade, coupled with the exquisite carving skills of craftsmen, often fascinate people. However, the Gemstone market is very chaotic. Take jadeite as an example. It may be acid-washed, filled with resin, artificially dyed, or mixed with other materials to impersonate jadeite. If you buy it without sufficient relevant knowledge and testing equipment, you may be easily deceived. Therefore, Hamlet Optics has launched a variety of jewelry microscopes for students taking jewelry courses. These microscopes are equipped with dark field focusing devices and are particularly suitable for observing translucent and semi-translucent Gemstone objects. Among them, the JH301 ultra-small binocular jewelry microscope is the model with the lowest entry threshold, suitable for students taking related courses and people who want to shop on Taobao. It can also be used as a simple solid dissecting microscope. **Product Features** **LED energy-saving low-temperature lighting** This machine uses LED white light as the lighting source, which has high brightness, low temperature to avoid damaging objects, stable color, and a lifespan of more than 10,000 hours. **Dark field focusing device** An essential function of a jewelry microscope is to add a light blocker to the light source that shines upward from bottom to top, which can disperse the light and achieve the effect of a black background and white edges when observing the object, so as to observe the crystal structure, lines, flaws and spots in the Gemstone. **Battery powered design** Most microscopes with lighting sources must rely on indoor power plugs, so they are limited to indoor use. 【JH301】 adopts battery-powered design, which makes it convenient to take the microscope outdoors for use. There is a battery compartment at the bottom of the body, which can be powered by two AA batteries. This product comes with 4 AA batteries for immediate use. **Fuselage structure** https://www.hwatang.com.tw/uploads/product/MJH301/MJH301-2-PL2.jpg Observe that the head is tilted 45 degrees, which is most suitable for Asians. The bottom of the body is hollowed out, making the entire machine lightweight, weighing only 680g. The eyepiece is a WF10x wide-angle eyepiece, which uses an optical glass lens group with high light transmittance. The objective lens is an Achromatic lens group, which can reduce the chromatic aberration produced at the edge of the specimen. Comes with a special jewelry clip that can hold smaller Gemstone objects with a good fit. The body is small and will not take up too much space even if placed at home. **Premium suede lens cleaning cloth** This product comes with a double-sided suede mirror cleaning cloth made in Taiwan, which can easily wipe off fingerprints, dirt, etc. on the mirror surface, jewelry and jade. The cloth is washable and reusable. **Precautions** ． Since the bottom of this machine is hollow, please avoid pulling the wires. If it is damaged by human factors, it is not covered by the warranty. ． If not in use for a long time, please remove the battery to avoid circuit damage caused by battery leakage. ． Please place it in a moisture-proof box after use to prevent moisture from causing the lens to become moldy. ． The microscope is a precision instrument. Be careful not to drop it or subject it to impact. ． When wiping the lens, do not wipe it back and forth vigorously, otherwise it will scratch the lens and affect the observation effect. ． The microscope and the lens have a precise optical path design, please do not disassemble them by yourself. **Product Specifications** Model: JH301 Total multiplier: 20x Observation head: binocular, fixed Tilt angle: 45 degrees Eyepiece: WF10x wide-angle eyepiece Objective lens: Achromatic objective lens 2x Focus system: coarse focusing mechanism Condenser: Dark field condenser Light source: 3W LED white light, brightness cannot be adjusted Battery used: AA battery*2 Size: Length 132 x Width 98 x Height 268~315mm Weight: 680g Origin: Authorized production in Mainland China Product warranty: one year Contents: Microscope body*1, WF10x eyepiece*2, dedicated jewelry clip, dust cover, AA battery* 2, product warranty card **Brand Introduction** https://live.staticflickr.com/65535/53802868882_756aba87d7_n.jpg Since its establishment in 1984, Huatang Optical Industrial Co., Ltd. has been engaged in the manufacturing and import of various magnifying glasses, telescopes, compasses, optical microscopes and other products.
