Optical Perfection, Day or Night
This particular zoom model offers an 8x to 16x magnification and a 40mm objective lens diameter. As it sounds, up to 16x magnification produces an image that appears as if the user were 16 times closer to their subject, while the objective lens diameter refers to how much light can be gathered to form that image. While for daytime use a lens diameter of 21 to 25mm is useful, for night-time viewing something between 35 to 50mm is recommended. Therefore the 40mm specification here indicates excellent suitability for low light visualisation.
Also worth considering for low light work is the exit pupil. Here that is 5.0 to 2.5mm, which for 8x40 binoculars, for example, is arrived at via 40 divided by 8 = 5 exit pupil in mm, so beyond the 2-3mm which is generally thought of as being suitable for daylight use. Another thing to take into account is the field of view, which here, due to the zoom capability, is 87-59 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation. Closest focusing distance is 10 metres.
