[Monochromators for cytophotometers and cytofluorimeters]

Two monochromators for microspectrophotometers are described. The attachments have been designed so that the peculiarities of the optical system of microscope have been taken into consideration. Simple, small sized monochromator is executed as a part of biological microscope and will be used mainly in cytophotometry. Another attachment is a commercially available single monochromator which has been easily adapted as a double one for using in cytophluorimetry by means of autoreflector set behing the exit split.
