Dedal-520, -541, -542, -552 night sight attachments install in front of day riflescope objective or other optical device (the field-glass, a telescope, photo/video equipment). Dedal-NV attachments have small weight, that allows fix them directly on day riflescope objective (field-glass) through a transitional ring or on the provided mounts (usually Weaver standard).

Night attachments using scheme provides the best quality of the image, big range of detection and recognition, than use of universal devices day/night and night devices behind an eyepiece of a day sight.

The main advantage of night attachments:

+ Dedal attachment in front of a day time sight doesn’t affect the latter’s zeroing
Keeps all capacities of a day riflescope intact
Specially designed night time fast optics
High quality image in the entire field of view

Dedal-542 is executed on high contrast technology (special calculated optical scheme and optical glasses, toughening of admissions during producing and assemblage of the lenses). That provides 20 % more contrast of a target/background in comparison with night rapid optics installed in Dedal-541 series.

Dedal-552 objective has a big exit pupil (34mm) that provides at the same weight and dimension, as in Dedal-542 working possibility with bigger magnification of day sights.

Dedal-541 produces with Gen. II + tubes.

Dedal-542,-552 produces with Gen. II +, III or XR-5 tubes.

In the complete set with Dedal-520-C the Buyer gets compact, easy and inexpensive device with the best Russian Gen. II + tube.

Devices produce  with the image intens. tube (tube) of Gen. III which provides the image in green or black-and-white spectrum of visibility.

Using of a black-and-white luminophor of the tube  provides bigger comfort of supervision and reduce the tiredness of an eye especially in winter conditions, but in certain cases (supervision in the summer wood, in the field) use traditionally yellow-green range of a luminophor provides big distance of supervision and recognition of the target owing to feature of a structure of an observers eye.
