CFF 400mm Ritchey - Chrétien
CFF's line of Ritchey-Chrétien reflectors is designed to offer uncompromising imaging quality, by integrating everything needed in a package containing high-quality hand-figured optics, top-quality finish & mechanics.
CFF is delivering the full range of substrates for these telescopes, starting with basic borosilicate glass (Supremax33), moving upwards in value/quality to Ultra-Low Expansion glass like Fused Silica/Quartz while for those who desire the best optical quality finish, they can manufacture the mirror starting with a cellular blank. The latter has the advantage of quickest cool down coupled with reduced weight (sensible weight differences/gains are observable in bigger sizes, 350 & 400mm).
