FAQ's

Real field of view
Real field of view will be the angle in the visible field, seen without moving the binoculars, measured from the central point of the objective lens. The larger the worth is, the wider the viewfield available. For example, binoculars with a wider field of view are advantageous for locating fast-moving wild birds inside viewfield. This applies to find small nebulas or perhaps a cluster of stars in astronomical observations.

Apparent field of view
Apparent field of view may be the angle in the magnified field whenever you look over binoculars.
The larger the apparent field of view is, the wider the joy of view you can see even at high magnifications.

With the standard method used previously, the apparent field of view was calculated by multiplying the real field of view with the binocular magnification. (With this formula, apparent field of view wider than 65˚ is named wide field of view.)

After revision, Nikon's figures are now based for the ISO 14132-1:2002 standard, and obtained from the following formula:

tan ω' = τ x tan ω
Apparent field of view: 2ω'
Real field of view: 2ω
Magnification: τ
(With this formula, apparent field of view wider than 60° is known as wide field of view.)

For example, the apparent field of view of 8x binoculars with an 7.0°real field of view is really as follows:
2ω' = 2 x tan-1 (r x tan ω)
= 2 x tan-1 (8 x tan 3.5)
= 52.1°

Relative Brightness
Relative brightness value is obtained by squaring the diameter of the exit pupil. The greater the relative brightness is, the brighter the look will be. With 8x42 binoculars, the brightness is (42÷8)2= 28.1. This means that if the magnification could be the same, the bigger the effective diameter with the objective lens, the brighter the style will be.

Do binoculars with the same exit pupil offer a similar brightness?

No. Brightness can vary even when the exit pupil could be the same. This is for the reason that amount of light reaching the viewer's eyes varies according towards the number of lens elements superiority lens/prism coatings. Superior optical design and highquality coating greatly contribute for the brightness of binoculars. Brightness values specified in product brochures, etc. are theoretical ones calculated inside design process. Take note these factors when comparing actual brightness values.

Prism Coatings
Multilayer coating can also be placed on prisms to raise transmittance. A roof prism system has one surface that doesn't feature total internal reflection, so vapor deposition with metals, etc. must be accustomed to boost the reflectivity with this surface. Also, phase-correction coating on roof surface ensures high-contrast images.
*Binoculars' brightness and contrast are impacted by not only prism coatings, but in addition the number of objective lens and eyepiece lens, and types of coatings.
Metal-vaporized, high-reflectivity prism coating
Using vacuum-vaporization technology, metallic material for example aluminum or silver is applied to the reverse side of the prism surface that just isn't totally reflective. This raises the reflectivity in the prism mirror surface.

Dielectric high-reflective multilayer prism coating
This coating features reflectance that exceeds 99%. By utilizing light interference, this coating assures high reflectivity through the full visible range, and ensures high color reproducibility.
Reflectance characteristics of prism coatings on mirror surface
The horizontal axis indicates the wavelength of light. The vertical axis indicates the reflectance of light.
Binoculars' brightness is determined not only with the reflective mirror, but additionally by the total optical system for example the amount of lenses and quality of coatings.
Phase-correction coating
A roof (Dach) surface could cause phase shift of sunshine that affects image resolution. This phenomenon is caused by phase differences arising from total light reflection on the roof (Dach) surface and yes it can happen with a good perfectly processed prism. Phase-correction coating is used to the surface to minimize loss in resolution, ensuring high-contrast images.

Twilight Factor
The factor that has the best impact on resolution or image detail, will likely be dependent upon the amount of sunshine available during enough time of observation. During daylight hours, when your skills pupil size will probably be only about 2 to 3mm, magnification will probably be the main aspect in image resolution. At night, using the eye pupil dilated to 6 to 8mm, aperture size could be the controlling factor. In twilight conditions both of the factors control resolution effectiveness as well as the twilight factor may be the term that compares binocular performance under these conditions.

The twilight factor is calculated by utilizing the square root of the product of the magnification and the aperture. The higher the twilight factor, the greater the resolution from the binocular when observing under dim light conditions. For example, a 10 X 40 (twilight factor 20) would effectively resolve better under these conditions when when compared with a 7 X 35 (twilight factor 15.4) even though the 10 X 40 includes a smaller exit pupil. Remember, however, the twilight factor does not take under consideration the transmittance or quality of the optical system.
America's best selling birding binocular is getting even better. The 2010 Monarch All Terrain Binocular now features dielectric high-reflective multilayer prism coating for brighter, sharper colors, crisp and drastically improved low-light performance. A new body style provides unparalleled strength and ruggedness in a package that is comfortable to transport all day
