"...there is no question these are first-rate eyepieces that will deliver views of planets as good as your telescope will allow — no ifs, ands, or buts about it." --August '04 Sky & Telescope review
Also, See review of TMBs on Anacortes Website.
TMB Super Monocentrics feature a cemented triplet eyepiece with two air-glass surfaces. These surfaces are fully multicoated using the best available multicoatings and yield 99% light transmission.
The eyepieces were designed by TMB-Optical/USA and are manufactured by a renowned optical company in Germany. This allows the use of the best possible glass from Schott-Mainz, as well as the smoothest polish.
