Day and night systems

Diffrent applications

One of the way to solve the problem is to use the day/night device with changing eyepiece (day/night rifle scope Dedal-DN-530). The advantage of this optical scheme is its low weight and speedof change of eyepiece modules. Device Dedal-DN-530 uses high-contrast objective lens of constantmagnification with aperture ratio F/1.5 and provides the qualitative image in day time and nightobserving conditions. It’s the best choice to provide one of the most compact and light weight unitswith night and day time operation system. However devices of this class are a little inferior in theirlimiting night distance to highly specialized night scopes.
