Advantages of the riflescope illuminated reticle with illuminated dot II The illuminated dot II was developed by DDoptics in Dresden. This new generation illuminated dot II is installed exclusively and in all riflescopes offered by DDoptics. New: The optional, intelligent IFiber additional control from DDoptics. DDoptics illuminated dot 2 Unfortunately, fine details such as the light unit are often skimped on. And this has far-reaching consequences! Not so with DDoptics. The illuminated dot II [...]
The different types of DDoptics binoculars Binoculars can be divided into two main types according to their basic construction: Construction with roof prism (different types of construction) or with Porro prism. Binocular prism systems Both designs have their unique advantages and disadvantages. In principle, Porro and roof prism binoculars can offer the same performance depending on the type of glass (BAK 4, crown glass, etc.), the amount of coating and the manufacturing quality. The details [...]
Different reticles for riflescopes DDoptics uses the following 3 reticles for its riflescopes, depending on the target optics: Reticle 4 with illuminated dot from DDoptics Reticle 4 ILU with illuminated dot II or IFiber Most hunters who choose a reticle with illuminated dot opt for this reticle 4. The illuminated dot is switched on in the dark. A light source shines through the built-in glass fibre. Fine [...]
How to recognise the quality of the illuminated reticle on riflescopes! The choice of reticle and the associated function of the illuminated dot is of crucial importance when making a purchase. At this point, we would like to give you some tips on what you should pay attention to when choosing the reticle and the illuminated dot and why! 1. is the light point really infinitely dimmable by 100%? Or is [...]
Explanation and function of parallax compensation If a shooter does not look through the eyepiece "straight" but "at an angle", an aiming error occurs - the so-called parallax. Parallax error in riflescopes The reason for this is the positioning of the eye outside the straight line that runs from the reticle centre to the target - the optical axis and visual axis are shifted against each other. This subsequently leads to incorrect [...]
The reticle in the 1st image plane in riflescopes With the reticle in the 1st image plane, the reticle simply enlarges with the magnification adjustment. The image of the object created in the 1st image plane is magnified and imaged in the second image plane. This means that the distances between the bars remain the same. Advantage: Easily recognisable bars in the reticle. However, as these - especially at high magnification [...]
Reticle in the 2nd image plane with riflescope and target optics The reticle in the 2nd image plane does not simply increase in size when looking through the target optics. The distances between the crossbars become smaller and smaller with increasing magnification. Reticles in the 2nd image plane (eyepiece image plane) only have defined distances at one magnification, but always look the same size to the eye, so they are [...]
Binoculars coated using RNP technology from DDoptics RNP Raindefender Nano Protection Thanks to the DDoptics RNP coating on the outer lens surfaces, water does not adhere to the glass but rolls off easily, making it easier to clean when dirty. Thanks to the new nano-coating technology, the RNP-coated optics from DDoptics are suitable for tough use in the worst weather conditions and in high humidity without any problems. Extract [...]
Binoculars and optics made of ED glass ED glass in binoculars ED glass effectively compensates for chromatic aberration (chromatic aberration = different coloured parts of a beam of light are refracted to different degrees - clearly visible as a colour fringe along edges) and thus contributes to images with superior contrast and outstanding resolution. The reward is exceptionally detailed, true-colour and vivid images. Under ED glass (Extra-Low Dispersion [...]
Calculation of minute of angle or MOA for target optics 1 MOA (one minute of angle or minute of angle) is 1/60th of a degree of angle. At a distance to the target of 100 m, an adjustment of 1 MOA therefore corresponds to an adjustment of 2.9 cm. Example calculation for understanding: The target distance (= radius): 100m or 10,000cm Circumference calculation: 2 x radius x 3.14 (PI) = 628.31m or 62,831.85cm 1 degree then corresponds to 1/360 of the [...]
ZF mounts - the most important connection between rifle and optics Today, a wide range of riflescope mounts from various manufacturers is available to gun buyers. High-quality mounts are now technically mature and enable an optimum connection between rifle and target optics. Perhaps often underestimated: As high-quality mounts are extremely precise and complex components with [...]
Night binoculars - Lightweight light collectors bring brightness into the dark There is a rule of thumb: "The larger the objective lens diameter, the brighter the night binoculars or their optics - but also the heavier." Which binoculars are ideal for twilight or hunting at night? When it comes to night binoculars, which are ideal for sitting game and for sows, the main [...]
