NIGHT VISION MONOCULARS
One of the more notable features about night vision monoculars is that they use only glass and the lenses used work together with tube that intensifies light resulting in sharper as well as brighter images even when lighting is poor. Some of the big names engaged in manufacturing these type of monoculars include ATN, Bushnell, Night Optics USA, N-Vision Optics, Newcon Optik as well as ITT, to name a few.
In fact, ATN night vision monoculars have been used by DEA as well as the FBI and they are also in use with NASA where they are used in space shuttle program. In fact, ATN is producing monoculars that can be used at night which are even used by US Special Forces while deployed in war zones such as in Iraq and even Afghanistan and there are several peacetime uses for such devices as well. Typically, you would have to pay between three hundred dollars upwards to even more than a thousand dollars for a good piece.
