PURPOSE:To obtain the maximum contrast with one filter for many dyed coloring matters, by arranging the filter, whose angle to the optical axis is variable, in the optical path from a light source to an eyepiece. CONSTITUTION:A filter supporting material 6 is placed on a filter receiver 5 of a microscope base 3. In the supporting material 6, a filter 7 is attached turnably around a rotating shaft 8, and the rotating angle is indicated by measures 10. In case that the transmission peak of the filter is matched to the absorption peak wavelength of used dyed coloring matters, the filter 7 is turned to find the position of the highest contrast. Thus, the maximum contrast is obtained with only one filter for many dyed coloring matters. |
