    摘要： An aperture stop for microscope condensers mounted to the lower part of a microscope condenser and comprising a fixed member and stop ring, the fixed member being provided with an index mark, the stop ring being provided with color marks of same colors as color bands provided to microscope objectives, the aperture stop being arranged that an aperture diameter corresponding to the numerical aperture of the objective to be used is obtained when one of the color marks having the same color as the color band of the objective to be used is set to the index mark, the aperture stop thus assuring simple and correct operation.
