microlux 4x13mm German pocket focus-free monocular telescope 4294413 (company goods)

https://www.hwatang.com.tw/uploads/product/content/bf76d846f9173195a97077eeaae4fe49.jpg **Germany Eschenbach Yishibao microlux micro series** **4x13mm German pocket focus-free monocular telescope 4294413** **Product Introduction** Eschenbach of Germany designed the microlux series of telescopes (Telescope / Monocular) visual aids for users with telescopic needs. They use the refractive optical system of the Keplerian telescope and add prisms to convert it into an upright image. The internal lens group is made of achromatic optical glass to reduce the problem of color fringing at the edge of the image, and is processed with MC (Multi-Coated) multi-layer coating to achieve sharp images with good contrast. It is often used to assist patients with amblyopia or low vision to see distant objects. Suitable for low vision assistive devices, viewing classroom blackboards, bus numbers, street house numbers, weak eye vision training, museum exhibition tours, outdoor travel, flower and butterfly viewing, insect observation, etc. ． microlux 4x13mm 4294413 is a focus-free model and is recommended to be used with original corrective glasses. ． The microlux 6x18mm 4294618 is a focus model that offers a lot of power and can be used with the naked eye. **Product Features** **High quality German optical glass** https://www.hwatang.com.tw/uploads/editor/Eschenbach-icon/Silikat-Lens-S2.jpg The lenses are optical glass lenses made in Germany, with a clear and transparent texture and a bright and sharp field of vision. **Achromatic Design** https://www.hwatang.com.tw/uploads/editor/Eschenbach-icon/Achromatic-Lens-S2.jpg Achromatic lenses are made by gluing a double convex lens and a plano-concave lens to filter mixed light sources and eliminate aberrations. **Focus-free optical technology** Designed for beginners and children, it does not require a complicated focusing mechanism inside the body. Simply pick up the telescope and look at the target to see a clear image. It also prevents children from accidentally breaking the focusing mechanism, allowing distant objects to remain in focus. **Reverse viewing increases field of view** A low-magnification telescope can be used as a "reversed telescope". When used normally, the image can be magnified by leaning your eyes against the eyepiece. Reversing the telescope and looking through the objective lens will reduce the image and distort the surrounding images, but it can increase the field of view, making it suitable for patients with visual field defects to perform fixed-point observation. **Reverse magnifying glass to easily read small print** Reverse the telescope and use the objective lens to see about 15mm near the object. It can be used as a magnifying glass with a magnification of 3 times. **Small and pocket-sized for easy storage** The microlux series monocular telescope is compact and can be operated with one hand. The lens can be extended/retracted by pressing the body, making it easy to store and put in a bag for use at any time. **Multi-Coated** Lens coating can reduce the loss of light caused by prism reflection, thereby increasing image brightness and contrast. "Multi-Coating" means that the internal lens group is coated with several layers of coating on the surface of the lens, and the imaging performance will be better than full-coating (Fully-Coated). **Sturdy Roof Prism System** https://www.hwatang.com.tw/uploads/product/content/a4b3367c63439e18467fb9953aa4cd53.jpg The monocular telescope with a roof prism system is shaped like a "line". The distance between the objective lenses is equivalent to the distance between the eyepieces. In order to make the light path from the objective lens to the eyepiece in a straight line, the distance between the two prisms is closer, and its precision must be required. This type of prism system is more complex, and the internal mirror groups are arranged more closely. The advantage is that it is small and sturdy. **Premium suede lens cleaning cloth [Taiwan only]** 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. The cloth can be washed and reused. **How to use** 1. Press the body to extend the lens. It is recommended to wear the original corrective glasses. 2. If the word microlux is facing you, it will act like a telescope when you look into the distance, magnifying distant objects. 3. With the word ESCHENBACH facing you, looking into the distance acts as a reverse telescope, shrinking distant objects to achieve the effect of extending your field of vision. 4. With the word ESCHENBACH facing you and the lens about 15mm away from the object being read, it is a reverse magnifier and can magnify 3 times. 5. Press the body again to retract the lens to prevent dust from entering. **Precautions** ． Do not drop or subject it to strong impact to avoid displacement of the internal mirror assembly of the telescope. ． Do not look directly at the sun or strong light through the telescope, as this may cause damage to your eyesight. ． This product is not waterproof. Please avoid using it when it rains or soaking it in water. If it comes into contact with water, please wipe it dry as soon as possible and store it in a moisture-proof box. ． This product does not have a focus wheel. If you have myopia or hyperopia, please wear your original glasses before using it to obtain clear images. **Product Specifications** Original manufacturer number: 4294413 Magnification: 4 times Objective lens diameter: 13mm Optical system: Keplerian Telescope Kepler Telescope Optical System Prism: Optical achromatic glass, BK-7 (boron silicate glass) prism Prism system: Roof vertical ridge prism system Lens coating: Multi-Coated Focusing mechanism: fixed-focus, no need to adjust focus Viewing angle: 13 degrees View range: 225m @ 1000m Minimum focal length: 2m (depending on individual vision) Maximum focal length: Infinity Exit pupil diameter: 3.25mm Relative brightness: 10.56 Good viewing distance: 10mm Close magnification: 3x (reverse use) Close focus distance: 15mm (reverse use) Material: ABS plastic Product size: length 48 x width 25 x height 38mm Weight: 46g Accessories: waist storage sleeve, hand strap, product warranty card Origin: Made in Japan under German authorization Product warranty: two years **Brand Introduction** https://www.hwatang.com.tw/uploads/editor/Eschenbach/eschenbach-logo2-M4.jpg?1501828202782 Founded in 1913, Eschenbach Optics is a world-leading German manufacturer of vision aids.
