KenMAX 8x20mm Japanese-Made Monocular Macro Short-Focus Telescope KM-820

**I.L.K. Ikeda Lens Co., Ltd. (Japan)** **KenMAX 8x20mm Japanese-Made Monocular Macro Short-Focus Telescope KM-820** **Product Introduction** The short-focus macro telescope utilizes a Keplerian telescope refraction optical system. This is an evolution of the Galilean telescope, replacing the original concave eyepiece with a convex lens. Originally used in astronomy, this design allows for a wide field of view and high magnification, though it produces an inverted image. By adding a prism between the two convex lenses, the image is corrected to be upright. Beyond being lightweight and compact with high resolution, its two primary features are its "Short Focus" capability—allowing for the observation of fine details at very close range—and a high diopter optical system, often used to assist individuals with low vision in viewing distant objects. It is suitable for low-vision assistance, reading classroom blackboards, bus numbers, street signs, visual training for the visually impaired, museum tours, outdoor travel, flower and butterfly viewing, and insect observation. The KenMAX series of short-focus macro telescopes, produced by Ikeda in Japan, features lenses and bodies manufactured in Japan. The internal lens groups are treated with FMC (Fully Multi-Coated) processing to provide stunning image quality. The series offers various magnification levels to suit different user needs. Certain models are compatible with an optional dedicated magnification base, converting the device into a simple upright-image microscope. This is ideal for inspecting printing dots, panels, circuit boards, quality control, authenticity verification, and biological observation. Its superior imaging, portability, and versatility make it a favorite among those who have used it. **Product Features** **FMC (Fully Multi-Coated)** https://www.hwatang.com.tw/uploads/product/content/c76baec0342749a0c4bd47f73bac1597.jpg Lens coatings reduce light loss caused by prism reflections, increasing image brightness and contrast. FMC (Fully Multi-Coated Optics) ensures the internal lens groups are completely covered, significantly enhancing light transmission and contrast for a brighter, sharper image. **Fold-down Eyecup** Users who do not wear glasses can use it directly, resting it comfortably against the eye socket. For users wearing glasses, simply fold the eyecup down to use. **(Optional) Dedicated Magnifier Base** https://www.hwatang.com.tw/uploads/product/content/387ffb767140beaa035ca6b133232870.jpg An optional KM-1LED magnifier base can be purchased to turn this into a simple upright-image microscope. Paired with the telescope's focus wheel, it can observe both flat and uneven surfaces, making it suitable for precise inspections of print dots, fibers, jewelry, minerals, and circuit boards. It can also function as a high-magnification vertical loupe. When the KM-1LED base is paired with the KM-412, it provides 12x magnification; 20x with the KM-616; and 25x with the KM-820. https://www.hwatang.com.tw/uploads/product/content/b0df1a55d83217e894d0661877b6f761.jpg **Instructions** https://www.hwatang.com.tw/uploads/product/content/03635af08c846121c1798459845e98e0.jpg 1. Remove the eyepiece and objective covers. The rubber part is the eyepiece. If not wearing glasses, use directly; if wearing glasses, fold the rubber eyepiece down. 2. Gently rest your eye against the eyepiece and look at the target object. Hold the eyepiece head with one hand and turn the focus wheel on the body with the other until the image becomes clear. 3. Retracting the body to its shortest length sets it for long-distance viewing with a focus at infinity; extending the body to its longest length sets it for macro viewing at close range. **Photos** https://www.hwatang.com.tw/uploads/product/content/4b673f459c3aa51839f48162944a1df1.jpg **Precautions** . The focal lengths described in the specifications are based on actual test results but may vary slightly depending on individual vision conditions. . Do not drop or subject the device to strong impacts to prevent misalignment of the internal lens groups. . Do not use the telescope to look directly at the sun or strong light, as this may cause eye damage. . This product is not waterproof. Avoid using it in the rain and do not submerge it in water. If it comes into contact with water, wipe it dry as soon as possible and store it in a dry box. . For safety, avoid observing dangerous creatures such as bees, spiders, or venomous snakes when using the macro mode. **Product Specifications** Model Number: KM-820 Magnification: 8x (Telescope) / 11x (Macro) Objective Diameter: 20mm Optical System: Keplerian Telescope Optical System Prism System: Roof Prism System Lens Material: Optical White Glass Lens Coating: Fully Multi-Coated Eyecup: Fold-down type Field of View: 6.8 degrees Field of View Range: 12m @ 100m Minimum Focus Distance: 30cm (at maximum extension) Maximum Focus Distance: Infinity (at shortest retraction) Exit Pupil Diameter: 2.5mm Relative Brightness: 6.2 Eye Relief: 12mm Material: Aluminum alloy Body Dimensions: Diameter 34 x Length 98mm Weight: 112g Included Accessories: Carrying case, eyepiece cover, objective cover, neck strap, warranty card Origin: Japan Warranty: One year **Brand Introduction** Originally named "Ikeda Lens Seisakusho," the company was founded in 1923 in Ikuno-ku, Osaka, Japan, specializing in lens production and processing. It was officially renamed "I.L.K. Ikeda Lens Co., Ltd." in 1962, focusing on the production and sale of magnifying glasses. They transformed the loupe from a reading tool for the elderly into a wide range of patented professional magnifying glasses and spectacles, helping people reduce eye strain and improve efficiency while working. Superior quality, diverse choices, and affordable pricing are the hallmarks of Ikeda products. LOUPE STUDIO is the online shop for Ikeda in Japan, highly popular throughout the country. Hwa-Tang Optical is a long-term partner of Ikeda in Taiwan.
