... The positive solution to this quadratic equation is fo = 0.5. Notice that if the working distance were larger, then fo could be larger too. But let’s use fo = 0.5here. This means that the eyepiece focal length should be 8/(3×0.5)=16/3=5.333 cm. Now we need to find some diameters for these lenses. Fo ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
