Fuji Photo Film Co., Ltd. (Fujifilm) was founded in 1934 with the mission of undertaking the production of photographic film in Japan. Since those embryonic days of corporate development, they have persevered and developed a myriad of technological innovations for the optics and imaging industries worldwide.
The Fujifilm S1240 D/N Stabiscope is both a day and night vision binocular. The eyepieces are easily interchanged so that your day time 12x40 binocular can quickly morph into a serious NVD with amazing image intensifying capabilities. The astounding abilities of this binocular do not stop here, there is also a state of the art gyroscopic image stabilization system built into this wondrous optical device. This image stabilization system delivers rock steady viewing under all conditions, in both the day and night time binocular configuration. When a successfully completed mission is your goal, the S1240 D/N Stabiscope helps you get the job done.
There are many different variables that affect the distance that one can see with a night vision device, among them the object's size, the level of details being sought from the object and the conditions of observation. Night vision devices detect much further under a full moon and clear skies than they will under a new moon and cloudy skies.
Many different formulas are used to determine the statistic of maximum viewing range and the method of calculation varies by manufacturer.
The important factors to consider when evaluating any night vision device are the intensifier tube's generation, s/n ratio, level of magnification, specified resolution, along with the clarity & light transmission efficiency of the optical system.
All night vision devices sold by B&H have mechanisms in place to protect the intensifier tube from a sudden burst of bright light, but this does not mean that bright light doesn't damage the device. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
