Description of Delta Extreme Binoculars
The massive binoculars of the Extreme series made by Delta Optical are extremely powerful and perfect for observations in challenging light conditions. You can also choose two models with 10x and 15x magnifications for long distance observations of the nature and other objects such as ships and aircraft due to high level of image detail. Because of the 70 mm objective lenses, these two models provide exceptionally bright images, with the help of Porro prism system. These binoculars are also ideal for astronomical observations, not only of stars, but also of planets, comets, galaxies, clusters etc. Extreme series is equipped with FCM multi-layers of coatings on ED glass that helps to enhance light transmission rate and makes lifelike images free of major distortions. These binoculars have also good protective features and are fog-proof and waterproof so you can easily use them when facing challenging terrain and weather. These very affordable binoculars won’t break the bank!
Important features
Delta Optical Extreme series have a Porro prism system that makes them incredibly bright, but also more sturdy and heavy. All the models in the series have therefore implemented tripod adaptable screw, because their power makes it quite hard to hold in hands and get steady images. The smallest models are much easier to carry, but it is still recommendable to mount them to a tripod. These binoculars have individual focusing system which means that you only have to make adjustments once and afterward, the binoculars focus themselves when looking at different distances. Individual focusing mechanism also protects them more than central focusing, because the housing doesn’t move. Very thick rubber armoring also protects them against impacts and gives them impervious ability. Extreme series are equipped with special rubber veneer that also helps to fight against corrosion and makes these binoculars extremely durable. You won’t have to worry when using them in the harsh weather conditions such as the rain, snow or deserts since they can operate in temperature range from -40 to 70°C. These binoculars are also filled with nitrogen gas that eliminates condensation that occurs on the inner glass surfaces due to temperature fluctuations and are thus fog-proof, so you will see clearly even at the dusk and at the dawn.
Optical properties
Extreme series is equipped with FCM multi-layers of coatings on ED glass that helps to enhance light transmission rate, colors, contrast and makes an incredible resolution overall. This modern optical solution also helps to eliminate chromatic aberration and other distortion such as flaring and ghosting. The image is corrected and flattened. They provide more than 90% of light transmission rate not only because of the high quality optical coatings and phase correction, but also because the traditional Porro prism system that is brighter than roof prism binoculars. The huge prisms inside these binoculars helps to eliminate vignetting. Eyecups has only one position but with large exit pupil distance still offers comfortable support and eye relief even for eye glass wearers and are also helping to cut the light from the sides.
Accessories
Delta Extreme series have included a neck strap, protective case for storage and a tripod adapter.
