Távcsövek / Docter Nobilem 8x56 B/ga Zöld 

Docter Nobilem 8x56 B/GAThe NOBILEM range offers pairs of binoculars of high performance being ideal for a large field of application: for hunting, forestry, expeditions, shipping, sports, mountain tours, hiking, wildlife observations, ornithology, building and construction industry etc. All binoculars of the series NOBILEM dispose of high optical performance parameters. Owing to the large variety of models, you will surely find the appropriate NOBILEM binocular for yourself. All models work with the PORRO prism system and offer a large field of view, a multi-level coating on all optical surfaces and eyepieces for spectacle-wearers. They are splash-proof and resistant to climatic conditions and can be attached to a tripod.                             When you want to observe something much better than with your naked eyes at night the NOBILEM 8x56 B/GA is the suitable optical model. A big lens diameter of 56 mm, a large exit pupil and the high optical quality of the glasses and prisms enable everyone „to know what’s what“ even under bad light conditions. Thus, this model is ideal for a large field of applications. Owing to its balanced combination of magnification and brightness and its exology, building and construction industry etc. The body of all NOBILEM binoculars is of robust aluminium diecast being insulated by special sealing elements. The armoring consists of ecologically beneficial thermoplastic elastomeric material which makes the model especially wear-resistant. Thus, the precision technique of every single pair of binoculars is protected against shock. A pair of binoculars of the series NOBILEM being finished in that way is weather-proof, dust-proof and resistant to climatic conditions. In addition to this, the surface material prevents the pair of binoculars from slipping during observation. It fits the hand comfortably and is suitable even for extended periods of use. Focusing via the conveniently situated central drive is easy and quick. It is so big that you can even do it when you wear gloves! NOBILEM binoculars are delivered with eyepiece and lens protective caps and with a carrying strap. For the NOBILEM binoculars we also offer textile cases and for the NAVIDOC models a carrying strap which can be attached for swimming. The range of NOBILEM binoculars also offers a specially developed ocular with fold down eyepiece being ergonomically adapted to the sharpe of the human eye. It affords spectacle wearers a full field of view. At high magnification, during extended periods of use or in case the observer has a shaky hand it is recommended to fix the binoculars on a tripod. All our NOBILEM models dispose of a tripod thread. The appropriate tripod adapters and clips are available as an accessory. Prism erecting system Named after its inventor Gnazio PORRO (1850), this prism erecting system was used by Ernst ABBE (1840 - 1905) in the first prism binoculars in 1894. Since then it has been the bestknown inversion system used in binoculars.The NOBILEM range includes a modified version of this image inversion system according to PORRO. In these binoculars which were specially designed for their application in the field of work, the advantages of the PORRO system over the prism system with roof edge are conspicuous: Highest quality of image By using PORRO prisms the disadvantages of the roof edge prisms (roof edges can generate double images) are avoided. The clear guidance of the rays through the prisms and the prevention of light incidence by using special NOBILEM prism supports result in an image of high contrast and brilliance. Higher light transmittance, brighter image,better suitability for observation at dusk PORRO prisms make the realization of considerably larger light transmission diameters possible. The image reversal is accomplished by means of only 4 reflecting surfaces, the function of which is based on the lossless principle of the total reflection. The sealing of the individual prisms of the NOBILEM system diminishes the number of glass-air-surfaces. Alltogether, a higher light transmittance, brighter images and better suitability for observation at dusk arise out of the application of this system. Better mechanical sturdiness The patented NOBILEM prism holder, as well as the cementing of the prism system guarantee a high sturdiness of the binocular adjustment to mechanical loading. Better observation By enlarging the observation basis, the ability to image things in three dimensions is supported in a better way, in particular in the close range. Unrestricted user comfort Owing to the lenses being positioned outwards even large lens diameters can be realized without reducing the smallest possible interocular distance like with the direct-vision design. Thus, an obviously bigger distance setting range and consequently more favourable observation possibilities for the user are guaranteed with NOBILEM devices.
