Canon 15x50 Image Stabilization All Weather Binoculars w/Case, Neck Strap & Batteries

Canon 15x50 Image Stabilization All Weather Binoculars w/Case, Neck Strap & Batteries from Canon
  • This pair of binoculars from Canon are unique among high-magnification binoculars because they incorporate Canon's remarkable Optical Image Stabilizer technology
  • The Image Stabilizer technology compensates for handshaking as well as minute vibrations at the touch of a button
  • It also features 15x zoom to accommodate wide-ranging activities
  • A 50mm objective lens for a wide, extra-bright field of view
  • Multi-Coated Ultra-Low Dispersion Objective Elements add contrast, clarity & color fidelity

With its wide 50mm objective lenses and high magnification,these rugged, all-weather Canon Image Stabilizer binoculars are destined to set a new and higher benchmark for image brightness, clarity and ergonomic design.

Leave your tripod at home when you use the new Canon 15x50 binoculars. Canon has once again made its world-renowned optical image stabilizer more convenient to use on this all-weather binocular. With a push of a button, bumpy images are stabilized instantly for maximum viewing. Multicoated ultralow dispersion (UD) objective elements add contrast, clarity, and color fidelity. Housed in a rugged, water-resistant, and slip-free rubber body, these binoculars can be used in rain or shine, whether in a football stadium or on the high seas. Stargazing is also possible with these versatile binoculars. The 15x50 is greatly improved over the previous model, with a larger 50mm objective lens, more convenient operation of the optical image stabilizer, and optional antifog eyepieces. Two AA batteries power the device. Also included in the package are a case, neck strap, and eyepiece covers.

Image Stabilization and More
With any high magnification binoculars, most users will experience frustrating image shake. Unless fixed to a tripod, image shake can render high magnification binoculars useless. Canon's IS technology is remarkably effective at eliminating this problem and is widely used by the television industry with Canon's professional broadcast quality video recording equipment. A special VAP (Vari-Angle Prism) corrective IS system sits between the objective lens group and the porro prism on each side of the binoculars. Within thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. The VAP shape alters to refract or 'bend' the light path by precisely the right amount, thus fully compensating for the vibration. It is this essentially immediate response that effectively suppresses image shake.

Super Spectra Coating
A number of optical factors affect the brightness of an image, including the amount of incidental light that is reflected by the lens. An uncoated lens will refelect away as much as 8% of the incidentail light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection.

What do the numbers mean?
15x50? 8x25? The two numbers used to describe any pair of binoculars are their magnification — 8x, 12x, 15x and so on — and the diameter of their objective lenses — 25mm, 36mm, 50mm, and so on. The larger the first number is, the larger the object will appear to be in the objective lens. For instance, if you use a 10x lens and look at an object that is 100 yards away, it appears to be the same size as an object located just 10 yards away. The second number, the size of the objective lens, is important because the larger the objective lens, the more light it can admit for brighter, more detailed images, and the better suited they will be for lowlight situations.

Adaptive Optics in Astronomy

Adaptive Optics in Astronomy Adaptive optics is a powerful new technique used to sharpen telescope images blurred by the Earth's atmosphere. This authoritative book is the first dedicated to the use of adaptive optics in astronomy. Mainly developed for defence applications, the technique of adaptive optics has only recently been introduced in astronomy. Already it has allowed ground-based telescopes to produce images with sharpness rivalling those from the Hubble Space Telescope. The technique is expected to revolutionise the future of ground-based optical astronomy. Written by an international team of experts who have pioneered the development of the field, this timely volume provides both a rigorous introduction to the technique and a comprehensive review of current and future systems. It is set to become the standard reference for graduate students, researchers and optical engineers in astronomy and other areas of science where adaptive optics is finding exciting new applications.
