Night Vision from Dedal

Fujinon is introducing a new pocket night scope called PS910III. The very important features of the new PS910III are a 2nd Generation image intensifier tube built in. This very high sensitivity and high resolution image intensifier ensures a clear and bright image even under very low light conditions.

2nd Generation also means that the life time of the image intensifier and its protection against bright light through automatic brightness control is very much improved compared to 1st Generation image intensifiers. Minimum lifetime of the image intensifier of the PS910III is 2500 hours constant running which equals 15 minutes operating time every day over a period of 28 years!

The 1:1 magnification objective lens makes the PS910III especially useful for general security observation and for navigation because objects are seen through the image intensifier in them same size and distance as with the naked eye. The PS910III is fully waterproof which is also very important for professional use on land and use for navigation at sea.
