PURPOSE:To enable changing of a visual field without moving a microscope for observation and sample by conducting the light from the sample via a reflection mirror to the microscope and changing the inclination of the reflection mirror thereby changing the visula field of the microscope. CONSTITUTION:A beam splitter 2 provided above a sample 1, a light source 3 disposed on the reflection side of the sample 1 with the splitter 2 in-between, a reflection mirror 4 provided diagonally in the reflecting optical path of the splitter 2, a displacement device 5 which displaces slightly the angle of the mirror 4 and a stereomicroscope 6 for observing the sample provided in the reflecting optical path of the mirror 4 are provided, by which a microscopic device 7 of a variable visual field type is constituted. If the angle of the mirror 4 is slightly inclined by the device 5, the different positions of the sample 1 are observed with the microscope 6 as shown by an alternate long and short dash line. |
