MICROMETER ADJUSTABLE SLITS
Micrometer adjustable slit assemblies are continuously variable from fully closed (4 µm) t o 3 mm
width. A height adjustment slide allows variation in the height from 3 to 12 mm. Benefits of the
micrometer adjustable slits are flexibility and high throughput. This type of slit is designed primarily
for versatility and convenience in changing resolution and throughput , which are related to the slit
width.
Figure 9: A Micrometer Adjustable Slit
The slit width setting is read on the micrometer. A set of numbers go around the turning dial.
Another set of numbers are located on the shaft. When the zeroes in both these locations line up,
the slit is fully closed. Turning the dial clockwise advanc es the dial position furt her down on t he
shaft, closer to the body of the micrometer. This opens the slit.
Use a 10x multiplier to convert the micrometer reading to the actual slit opening size. For
example, turning the dial one full revolution starting from the fully closed position will give a
reading of 50 on the micrometer. Using the multiplier, this indicates the micrometer width is set t o
500 um. If unsure of the reading, begin at the fully closed position and add up each full revolut ion
made.
