How Binoculars Work
Binoculars are essentially a series of mirrors and prisms made of glass that take incoming light and provide the viewer with a magnified image. Each half of the binocular has three major parts.
The lenses at the front of the binoculars, the largest lenses, are called the Objective Lenses. The Objective Lens is where all the light comes into the binoculars. The Objective Lens focuses the light coming into the binoculars, and projects the image it receives as an upside-down image into the binoculars. In this way, the Objective Lens is a refracting lens. The larger the Objective Lens, the brighter the final image will be since it can take in more light. The trade off, however, is in convenience, as a larger Objective Lens will result in larger and heavier binoculars. Of course, higher quality lenses can be brighter than cheaper Objective Lenses of any size. Indeed, to ensure that the Objective Lens projects the sharpest image possible, it is important to use a high quality lens. With lower quality lenses, not all the light will be refracted at the same angle, causing the final image to be distorted in shape and color.
The image is turned the right way up by the second major part, the prism. In the common Porro design, the image is turned the right way up by two prisms set at right angles to each other. This is what accounts for the traditional binocular shape. For more money, you can get binoculars with a roof prism setting that allows for a more streamlined design. No matter what layout the prisms use, the final result is always the same. The prisms then project the corrected image down the binoculars towards the last major component.
The third major part of the binoculars is the eyepiece lenses. These lenses fulfill the binoculars' main purpose of magnifying images. The eyepiece lenses then project the magnified, right way up image to the viewer's eyes. It is important to consider this last step, from the eyepiece lenses to the viewer's eyes. Every pair of binoculars has a different eye relief, or optimum distance between the viewer's eyes and the eyepiece lenses. In particular, if you wear glasses, you should look for binoculars that have a long eye relief. So, now that you know how binoculars work, get out there and try some!

Two Different Types Of Binoculars Mount
The average binoculars mount can support anywhere from three to three hundred pounds. The binoculars mount ranges in different sizes that includes a smaller model to a heavier duty model. Prices vary for a binoculars mount, but can range up to $40 or more.
A binoculars mount generally is available in two different styles. Those styles are the parallelogram mounts and the mirror mounts. Also, the binoculars mount generally accommodates big binoculars. Big binoculars are defined as those binoculars where the objectives lenses are 50mm or above.
Parallelogram Mounts
This particular binoculars mount allows the viewer to change their body position without moving the binoculars. This design allows for the binoculars to stay focused on the object being viewed Also, the uniqueness of this particular binoculars mount, allows for the binoculars to be brought to the eyes of the viewer and not vice versa
Other benefits of the parallelogram mount allows for free hand movement when the binoculars are mounted on this apparatus. Additionally, this mount can be further mounted on to the average tripod or to a telescope. This adaptive feature allows for the mounted binoculars to be adjusted to various heights and therefore accommodate the viewing stature represented by the individual.
Mirror Mount
This type of binoculars mount features the use of mirrors in providing for a good and comfortable binocular viewing experience.
Similar to the style of using a microscope, the binoculars are mounted on to the device at an angle to where the binoculars look downward. This angle of viewing directly peers into a mirror which is part of the construction of this style of binoculars mount. The binoculars remain stationary and the field of viewing is changed by angling the adjustable mirror. The reflecting image, captured by the mirror, is then viewed by the binoculars.
The resulting viewing process of this binoculars mount eliminates the need to manually hold the binoculars to the eyes while standing or sitting. The resulting benefit includes the reduction of strain placed on the neck, back and arms when holding the binoculars up to the eyes for viewing. Also, with the weight of the binoculars being supported by the mount, the time of viewing can be increased.
As with the parallelogram mount, the mirror mount can be attached to the average tripod and adjusted to accommodate the varied heights of the viewer.
