Baader Fringe Killer Filter 31.7mm

,li> This would be a contradiction in itself – only made possible by applying modern DWDM plasma assisted coating technology
 Allowing almost a hundred coating layers to be accumulated onto a planoptically polished substrate – without destroying the optical figure! This fineoptical tool will help a small refractor to really put the advertized magnification within reach. Performance rivals that of the most expensive color correcting lens systems, costing 20 times as much!
