**Japan ILK Ikeda Reinko Industry Co., Ltd.** https://www.hwatang.com.tw/uploads/editor/IL.K/ILK-LOGO-M3.jpg?1497318689922 **KenMAX 2.8x9mm Japanese-made monocular macro short-focus telescope with ring KM-289** **product description** The short-focus macro telescope belongs to the refraction optical system of the Keplerian Telescope. The Galileo telescope is modified from the original concave lens eyepiece to a convex lens. It was originally used in astronomy and can be made into a large field of view, high magnification but upside down. Astronomical telescope for imaging. Afterwards, a dimple was added between the two convex lenses to convert it to an upright image. Short-focus macro telescopes have the advantages of lightness, thinness, shortness, and high resolution. The two biggest features are "Short Focus", which can view details of close objects at a short distance; the optical system can also provide high diopter. It is often used to assist amblyopia, low-vision (Low-Vision) patients to see distant objects. It is suitable for low vision aids, blackboards for viewing classes, bus numbers, street numbers, low vision training, museum exhibition tours, outdoor tourism, flower viewing, butterfly viewing, and insect observation. The KenMAX series of short-focus macro telescopes produced by Ikeda, Japan, the lens and body are made in Japan, and the internal lens group is processed with FMC (Fully-Multi-Coated) full-multi-coated multilayer coating to provide stunning imaging quality. The series of products have a variety of magnifications for users with different needs to choose. Some models can be equipped with a dedicated doubler lens base, as a simple microscope for upright imaging, suitable for printing dot inspection, panel, circuit board inspection, and quality control inspection , Authenticity identification, biological observation, etc. The high-quality imaging, convenient portability, and multiple uses make the people who have used it fall in love with it. **feature of product** **FMC full coverage multilayer coating** https://www.hwatang.com.tw/uploads/product/content/c76baec0342749a0c4bd47f73bac1597.jpg The lens coating can reduce the loss caused by the reflection of light on the prism, so as to increase the brightness and contrast of the image. FMC (Fully-Multi-Coated Optics), the internal lens group is completely covered with a multilayer coating, which can greatly increase the light transmittance and contrast of the optical lens group to obtain brighter and sharper images. **Metal finger grip** https://www.hwatang.com.tw/uploads/product/content/9bbc3409c5b0358f734f1ec48fac9f06.jpg Due to the small size of this product, it may not be easy to handle for some users. Therefore, the design of the finger grip ring is added, and the eyepiece of the telescope can be turned away and installed in the grip ring to facilitate long-term access. https://www.hwatang.com.tw/uploads/product/content/d4eff9e978606e08c082b867f76dea19.jpg **Reverse observation increases the field of view** A low-magnification telescope can be used as a "reversed telescope". In normal use, the image can be magnified by lightly relying on the eyepiece to observe; if the telescope is inverted and the eye is viewed from the objective lens, the image will be reduced and the surrounding image will be distorted , But can increase the field of view, suitable for fixed-point observation of patients with visual field defects. **Fold down eye mask** Users who do not wear glasses can use it directly, relying on the eye sockets for the most comfortable observation; users who wear glasses need to fold down the eye mask to watch. **How to use** https://www.hwatang.com.tw/uploads/product/content/03635af08c846121c1798459845e98e0.jpg 1. Remove the eyepiece cap and objective lens cap. The rubber part is the eyepiece, if you are observing with the naked eye, you can use it directly; if you wear glasses, please fold down the rubber at the eyepiece. 2. Keep your eyes lightly on the eyepiece and look at the target object. Hold the eyepiece with one hand and turn the focus wheel of the body with the other hand to adjust the focus. The image will change from blurry to clear. 3. When the body is reduced to the shortest distance, it is telephoto, and the focal length is infinity; when the body is turned to the longest distance, it is macro, which can be viewed at close range. https://www.hwatang.com.tw/uploads/product/content/a3cffa0f329e531935452e603c1453d9.jpg **Precautions** . The focal length stated in the specifications is the actual test result, but it may be slightly different due to different personal vision conditions. . Please do not drop it or subject it to strong impact to avoid the deviation of the internal mirror group of the telescope. . Do not use the telescope to directly watch the sun or strong light, which may cause damage to your eyes. . This product has no waterproof function. Please avoid using it when it rains or soaking in water. If it encounters water, please dry it as soon as possible and store it in a moisture-proof box. . To ensure safe use, please avoid watching dangerous creatures such as bees, spiders, and venomous snakes during macro observation. **Product specifications** Original Factory Number: KM-289 Magnification: 2.8 times for telephoto / 3.6 times for macro Objective lens diameter: 9mm Optical system: Keplerian Telescope Keplerian Telescope optical system 稜鏡 system: Roof vertical roof ridge system Lens material: optical white glass Lens coating: Fully-Multi-Coated Eye mask: Fold down eye mask Field of view: 12.5 degrees Field of view: 22m @ 100m Minimum focusing distance: 15cm (the body extends to the longest) The farthest focusing distance: infinity (the body shrinks to the shortest) Projection pupil diameter: 3.2mm Relative brightness: 10.2 Good viewing distance: 11mm Material: aluminum alloy Body size: diameter 22x length 46mm Weight: 29g Accessories: metal finger grip ring, storage sleeve, eyepiece cover, objective lens cover, neck lanyard, product warranty card Origin: Japan Product warranty: one year **brand introduction** https://www.hwatang.com.tw/uploads/editor/IL.K/ILK-logo3-M2.jpg?1497236734019 Japan Ikeda Reinko Industry Co., Ltd. was established in Showa 37 (1962).
