Lumicon Star DiagonalAbout The Lumicon Star Diagonal 1.25" Enhanced Diagonal 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. LumiBrite The Lumicon 1.25" LumiBrite Dielectric Coated Diagonal reflects up to 99 percent of the light from the telescope's primary optics into your eyepiece. Its single 1/10 wave precision polished surface is superior to the three surfaces of prism diagonals. The Dielectric Coating is smoother and even more durable than an enhanced aluminum coating, providing maximum image contrast. Lumicon collimates each and every LumiBrite Star Diagonal with 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. 90 Degree Correct Image The Lumicon 1.25" 90 degree Correct Image Diagonal provides a corrected image(left/right; up/down) for finder and spotting scopes. May also be used on refractors and SCTs. Includes filter threads. Multi-Coated Prism The 1.25" Multi-Coated Prism Diagonal is a Lumicon-quality prism diagonal at an entry-level price Return From Lumicon Star Diagonal To Star Diagonal Main Page Privacy Policy | Disclaimer | Sitemap | Contact | Link To Us
