The reticle in the second image plane of riflescopes

Reticle second image plane for riflescopes
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 with increasing Magnification always smaller. Reticles in the 2nd image plane (eyepiece image plane) only have defined distances at one magnification, see for the Eye but always the same size, so they are [...]

ED glass - Extra Low Dispersion glass

ED glass for binoculars and optics
Binoculars and optics from 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 angular minute or MOA

Calculation of angular minute MOA for riflescope
Calculation of Angular minute or MOA for target optics 1 MOA (one minute of angle or minute of angle) is 1/60th of an angle degree. At a distance to the target of 100 metres, 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 [...]

Riflescope mounts
