View source for NS-71

The NS-71 is a Polish generation-0 night vision device.

It was intended to be used by sappers and combat engineers.  It mounts to helmets via a clamp fitted to the main body of the device. Its high voltage transformer box is slung near the waist and uses 6 volt.  Mounted on top of the main body of the device is an IR lamp, that can be toggled via a switch on the transformer. The lamp has three settings, off, scatter, and beam. With the light turned on the device draws much more current than the PNV-57s ~10mA.<ref>https://forum.astronomie.de/threads/infrarot-nachtsichtgeraet-nachtsichtbrille-pnv-57-binokular.344107/</ref> while the body of the device may look similar to the PNV-57, the lenses on the NS-71 have variable focus. Additionally the lenses are linked together via an assembly similar to the one found on the type 85. The device is similar in function to the Soviet PNR-1.<ref>https://pliki.elektroda.pl/516835,ns-71.html</ref>
