BINOCULARS, what do all the features mean?
Magnification
• Number of times the object being viewed is enlarged e.g. 8x 25 = objects are 8 times bigger than seen with the naked eye
Objective Lens (mm)
• Diameter of front lens e.g. 8x 25 = 25mm lens
• The larger the number = maximizes light which leads to sharper image
Prism Type
• Roof Long, straight tube. The prisms overlap and are in a straight line.
• Porro The objective is offset from the eyepiece, gives a greater depth of perception.
• Reverse Porro The objective is offset from he eyepiece, leads to 30% reduction in size of binocular.
Optical Coating
• Various coating processes on the lenses and prisms determine the brightness and light gathering, providing higher contrast and brighter, sharper images.
• Fully Coated Single layer on all outer lens surface
• Multi-Coated Multiple layers on either lens surface
• Fully Multi-Coated Multiple layer on all outer lenses
Field of View
• This is the side-to-side linear measurement of the circular field seen through the binoculars. The higher the magnification the narrower the field of view.
• Bird watching-medium magnification = wide field of view.
• Plane spotting - high magnification = narrow field of view to read plane numbers!
Close Focus
• The closest distance to the object that the binoculars can be used while retaining a sharp focus
