This class of objectives provides an attractive alternative to ?Achroplan? objectives, both in routine and research applications. ?A-Plan? objectives provide rich contrast and can be used with eyepieces with a field of view up to 23 mm.They allow contrasting methods ranging from brightfield to phase contrast and for excitation wavelength within the visible spectrum they can be used for epifluorescence work.
