Baader T2 BBHS-Sitall diagonal mirror - dual T2-threads 2456103
T-2 BBHS® Mirror Diagonal, solid metal body only, with male/female T-2 thread
(BBHS® = broadband hardsilver coating with dielectric protective overcoating)
The T-2-star-diagonal is now available with two different mirrors, Maxbright (#2456100), or BBHS® (#2456103), serving different purposes. The Maxbright (#2456100) still is available with our time tested dielectric coating.
Alternatively the latest addition to the family is the same housing but with hardened silver with dielectric overcoating (#2456103). We tested our new hard-silver coating to be much higher in brilliance than cheap dielectric coatings of other manufacturers. BTW. this is the only diagonal mirror of this size made of Sitall-glass ceramics.
The latest addition to the Baader Diagonal family. This diagonal has the same casing as the Maxbright Diagonal (#2456100) but with hardened silver with dielectric overcoating. This is the only diagonal mirror of this size made of Sitall-glass ceramics.
Sitall glass is a crystalline glass ceramic with ultra low thermal expansion properties, low thermal expansion is a critical feature needed in the manufacture of optical elements for high quality optical telescopes and accessories such as this mirror diagonal.
