Metallic microscopes have more adjustment points than ordinary microscopes. Depending on the adjustment, the light intensity may decline extremely. If it is dark (or no light comes out) please check as the following instructions.
■Polarization observation change lever | |
When both levers protrude, the light path is blocked. |
|
Be make sure to switch between polarization observation and normal observation. |
|
■Optical axis adjustment of light source | |
If the optical axis and the tilt of the light source deviate greatly, the light irradiated from the objective lens may be drastically declined. |
|
■Adjusting the aperture in the middle of the optical path | |
There are two aperture functions in the middle of the light path. If this is narrowed too much, the irradiated light may decay considerably. |
