Mechanical Properties:

The only high quality filters planoptically polished to 1/4 wave and parfocal.
2mm glass thickness and LPFC Low Profile Filter Cells
Baader LRGBC filters have elaborate anti-reflection coatings for superior performance.
Each filter is coated separately, not just cut or bored from a large coated plate. Individual hard coatings ensure sealed edges that are impermeable to moisture (bored filters have the coating microcracked all around the edge).
Baader filters feature hard coatings that may be cleaned with Baader Optical Wonder fluid without scratches.
Optical Properties:

Less reflections than competing designs.
RGB-imaging allows equal weighting factors for each channel, very important for automated imaging.
Designed for maximum contrast and with extremely high gradients for clear differentiation of colours.
OIII emission overlaps on B/G-filters with maximum transmission to allow efficient and natural colour imaging.
R-filter delivers maximum transmission for H-alpha and S II while efficiently cutting IR.
Gap between G/R-filters serves to reduce light pollution from Mercury and Sodium lamps and improves colour balance and separation.
