Our alignment telescopes are known for their robust construction and ability to maintain adjustment through thick and thin. They were originally designed by Keuffel and Esser (a.k.a. K+E or Cubic Precision). Today we continue their tradition of old-world craftsmanship by manufacturing these precision optical instruments. We offer telescopes with dual-axis micrometers, autocollimation capabilities (including bright line autocollimation), as well as the simpler straight-line alignment telescopes.
