Claims

[Scope of utility model registration request]

an excitation filter placed on the incident side of the illumination light;
A dichroic mirror that guides illumination light incident through the excitation filter to the objective lens side and guides observation light from the sample to the eyepiece barrel side of the microscope body; A cube having an absorption filter into which observation light via a dichroic mirror is incident, and a turret to which the cube is removably attached and having an observation light passage hole through which observation light obtained through the absorption filter passes, An epi-fluorescence illumination device characterized in that an auxiliary absorption filter is provided in addition to the absorption filter in the observation light passage hole provided in the turret.
