| Untitled document This device with image intesifier tube Gen.2+ has resolution minimal 45 lp/mm, S/N ratio 20-22, photocathode sensitivity minimal 500 µA/lum and expected lifetime 5000 hours. Night vision attachment DN33 is intended for application together with majority of day sights. DN33 design allows quickly and safe to attach it to the front of a day sight and to make possible aiming shots in low light conditions without additional adjusting day sight. Ergonomic design, high aperture optics, reliability, compactness and light weight provide comfort to a user during observation and shooting at night and twilling.
DN33 design provides the possibility to mount it on different types of day sights: 1. With the help of a special adaptor the night vision attachment can be twisted in an objective lens of a day sight, if it has a thread inside of a blend.
2. By means of special adaptors it is possible to attach the night vision attachment DN33 to an objective lens. The set of inserts of different sizes provides its attaching to the following objective lens diameters: 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62.
3. Using a special adaptor it is possible to mount the attachment on a weaver directly in front of an objective lens of a day sight. Specifications:
