Baader Fringe Killer Filter 31.7mm 2458370
Planoptically Polished with Phantom Coating Group (PCG).
The BAADER Fringe-Killer Filter minimizes unwanted blue fringing, comparable to a Minus-Violet-Filter, while retaining a very pleasing color balance. 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!
(Note: for solar observation use only in combination with Baader AstroSolar Safety Film!)
