- General
- Product Name: 8 x 21 Compact Binoculars
- Brand: U.S. Army
- Model Number: US-BC821
- Color: Black
- Imaging
- Magnification: 8 times
- Objective Lens Diameter: 21 millimeters (Generally, the larger the diameter of the objective lens, the greater the light-collecting power and the brighter images will appear.)
- Close Focusing Distance: 16.4 feet (The closest distance the user can be from an object to obtain a clear, focused view through the lens.)
- Angular Field Of View (Apparent/degree): 57.6 degrees (Measurement of the angle of the magnified field seen through the lens. The greater the number, the wider the field of view that can be seen.)
- Angular Field Of View (Real/degree): 7.2 degrees (Measurement of the angle of the visible field seen through the lens (without magnification). The greater the number, the wider the area that can be viewed.)
- Features
- Size: Compact
- Prism Type: Porro (Prisms ensure the proper horizontal and vertical orientation of the view. There are two main types: roof and Porro. Roof prisms, typically more expensive than the alternative, have a more streamlined design due to their glass elements being in line with one another. Porro prisms, though they contribute to a larger form factor, typically provide a wider field of view than roof prisms.)
- Tripod Mountable: No
- Eyecup Type: Other (In addition to blocking peripheral light, adjustable eyecups can limit or expand the field of view as well as promote comfort for the user.)
- Exit Pupil: 2.7 millimeters (The diameter of the beam of light that travels through the lens to the user's eye. Generally, the larger this measurement, the greater the relative brightness and detail of the image.)
- Lens Coating: Multilayer coated (Chemical coatings on a lens reduce reflective light loss and improve light transmission. The different coating levels indicate the number of anti-reflective layers and the lens surfaces to which they're applied, ranging from coated (the most basic) to fully multi-coated (typical of high-end optics).)
- Focus System: Center (The most common binocular focusing system is center focus, which features a centered wheel or lever (InstaFocus) between the barrels, and usually additional diopter adjustment. Individual focus binoculars allows each eyepiece to be adjusted independently.)
- Eye Relief: 10 millimeters (The maximum distance between the eyepiece lens and user's eye at which the full field of view can be seen.)
- Dimensions
- Product Height: 4.5 inches (The out of box height of the item. Height is measured as the vertical distance from the bottom of the item to the top as it would be primarily used or placed.)
- Product Width: 3.13 inches (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
- Product Depth: 2.13 inches (The out of box depth of the item. Depth is measured as the distance from the front of the item to the back as it would be primarily used or placed.)
