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. The VAP shape alters to refract or 'bend' the light path by precisely the right amount, thus fully compensating for the vibration. (Featuring an Image Stabilizer and All-Weather design). It is this essentially immediate response that effectively suppresses image shake. Unless fixed to a tripod, image shake can render high magnification binoculars useless. This polycarbonate window is 5/8" thick. Check the thickness of the glass you are replacing as most is only 3/8" thick The system employs a Vari-Angle Prism, dual transparent plates, independent vertical and horizontal sensors, and a dedicated microprocessor to continuously adjust the prism to maintain a steady image. The 18x50 IS binoculars feature a water-resistant, shock-resistant rubber coating for a nonslip grip and better durability. Within thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. Controls for focusing and image stabilization are centrally located and accessible by both hands. 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. These binoculars provide long eye relief for extra comfort. 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. 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.

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. These binoculars deliver high magnification and wide-field viewing. Canon's Super Spectra Coating prevents that reflection.
