Baader Clearglass Filter (C) for focusing / dust protection

• Baader Premium grade impermeable RGB-C Clearglass Filters.
• The Baader clear glass filters are used to focus a camera when using very narrow band line filters (due to same mechanical thickness).
• Alternative function: e.g. our Protective Canon EOS T-Ring uses a clear glass filter for dust protection
• NO halos, NO reflections, NO ghosting
• non-ageing sealed coating edges

Please note: We have not planned to produce also a CMOS-optimized version of this clear filter because there is no necessity to do so. Our 7-layer BBAR(BroadBandAntiReflection) -coatings on both sides of the glass-substrate cannot be essentially improved.
