The Lumicon 1.25" Enhanced Aluminum Diagonal reflects 96 to 97 percent of the light from the telescope's primary optics directly into your eyepiece. Its single 1/8 wave precision-polished surface is superior to the three surfaces of prism diagonals. Lumicon collimates each diagonal mirror via a double-pass collimator, ensuring that the light reflected from the diagonal is perfectly perpendicular to the telescope's optical axis. The telescope-side of all of Lumicon's diagonals are threaded for filters, so you can switch eyepieces while leaving your favorite Lumicon filter in place.
