These objectives have been designed especially for qualitative and quantitative analysis of ion movements and for particularly critical fluorescence methods (e.g. chromosome studies in human and cytogenetics). These objectives are distinguished by high numerical apertures and highest transmission at wavelengths even of 340 nm. Field flattening is sufficient up to a field of 20 mm.
