However, if the scope you're considering has a maximum magnification
of more than 10X and you plan on living in the top half of the magnification
range, FFP reticles are the way to go.
Correlations between white light magnification
and pathological findings
A rear focal plane reticle (also known as a second focal plane reticle) is more traditional and keeps the reticle clearly visible and the same size In all magnifications
Target sights exceed 40X, double the magnification
of the spotting scopes I used in competition!
Placing the reticle in the first focal plane allows the mil/MOA marks to be used at any magnification
setting, so the rifleman can adjust his magnification
to fit his particular needs, knowing his reticle is still calibrated.
Using the same focus settings at the highest available magnification
that a transmissive tube can achieve (FIGURE 4), however, shows the differences very clearly on the details of the 25 [micro]m diameter wires.
This 100,000-fold intensity increase is simply the magnification
squared, which means a magnification
However, 74% of all the participants strongly agreed that magnification
loupes made exploring easier and 67% strongly agreed that magnification
loupes improved their posture.
The Rohs-compliant objectives are available in four models with 2X magnification
, with focal lengths of 8mm or 10mm.
These low vision aids work on a principle of using magnification
to increase the retinal image size.
The medium-powered lens (4X) had increased magnification
, but also gave us a slightly blurry target.
(22) While properly fitted, magnification
loupes have been associated with improved posture, there is limited quantitative research to support this assumption.
