We are proud to present the Discovery range of optical instruments, manufactured by Levenhuk and sponsored by Discovery.
The Discovery Crafts DHR 20 is both a handy magnifying device and a pair of safety goggles for any precision work. As it is secured to the head, your hands remain free, allowing for a wide variety of applications for this instrument. The features of this magnifying glass will be appreciated by jewellers, watchmakers, technicians in repair centres, model-makers, and others.
The tool comes with interchangeable lenses offering various magnifications; up to two lenses can be fitted to the frame at the same time. In addition, there is also a small lens designed to be positioned in front of the right eye, which can be rotated to the side. By combining the lenses, you can optimally adjust the magnification for each specific task. All lenses are made from durable optical polymer glass with a high degree of transparency.
The headband of the magnifying glasses is adjustable, ensuring a secure fit on the user’s head. It features LED lighting with adjustable brightness. The light is powered by a rechargeable battery, with the obvious advantage of not having to buy replacement batteries. The battery is recharged via a micro-USB/USB cable.
