Premium quality coating is applied that offers optimum light transmission. The high optical quality of the Baader narrowband filters guarantees no loss in sharpness or contrast. Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface. This special custom polishing operation sets Baader filters apart from the standard commercially precision polished filter substrates used by most other filter manufacturers. The front 'crown' of the filter incorporates milled notches which make handling and threading the filter a more secure operation in the dark.
