This is a high quality optical microscope with a stage for wafer inspection. It has objectives:
| 5× | 10× | 20× | 50× | 100× | 150× |
Please note! The objectives are motor driven, you do NOT move the objectives by hand.
There is a timer in the wall socket to prevent the microscope from being forgotten with the lamp on. The wall socket is on the right hand wall when you are at the front of the microscope.
Normally the ON/OFF switch is on since the timer in the wall socket shut it off. The ON/Off is located at the right back of the microscope, see picture below.
At the front to the left there are two buttons to change the magnification. The top left is labeled "OBJ H" for increasing magnification, and the bottom left is labeled "L" for decreasing the magnification.
Underneath these buttons there is a wheel to control the lamp intensity.
On the right side of the front are buttons to control the aperture diaphragm "A.S." and to select the illumination. The aperture diaphragm is NOT to control the intensity of the illumination, it also affects the depth of focus. It should normally be set so that there is a slight decrease of intensity compared to the aperture diaphragm fully open.
The illumination selector, "EPI" and "DIA", should normally be set to "EPI", this sets illumination from above for opaque specimens.
The focusing knobs work in the same way as for the other microscopes in the lab. The outermost knob is the fine focus, the next is the coarse focus, the inner ring is to adjust the friction and to adjust the maximum height to move the stage.
The stage is moved by the two vertical knobs next to the right hand fine focus knob, underneath the stage. The big handle at the far right should normally not be used to move the stage.
There is now a camera attached to the top port of the microscope. It is the same type of camera as on the first (nearest) microscope in the process lab.
