How do you calculate eyepiece units?
Calculate the distance in micrometres of one division on the eyepiece graticule.
- The distance of 250 μm on the stage micrometer lines up against two divisions at 10 and 61 on the eyepiece graticule.
- 61 − 10 = 51 divisions on the eyepiece graticule are equivalent to 250 μm on the stage micrometer.
Why is the graticule calibrated?
So it is in focus with image of the specimen. To calibrate the eyepiece graticule with a particular objective the stage micrometer is viewed through the microscope. When calibrating it is essential to ensure the same settings on the viewing head are used for calibration and subsequent measurements.

How to add graticules to the edge of a map?
Click on ‘Line Style’ to get the Symbol Selector dialog. On the left-hand side of the dialog note the ‘Symbol layers’ pane. Select the item labelled ‘Simple Line’ and click the ‘Symbol layer type’ drop-down list on the top right (currently also set to ‘Simple Line’) and change it to ‘Marker Line’. You will get a load of red dots.
Where do I find graticule intervals in ArcGIS?
Click Customize > ArcMap Options, click the General tab, then check the Wizard Mode option. You can specify the graticule intervals in decimal degrees or degrees and decimal minutes instead of degrees/minutes/seconds (the default).
How to change the size of the graticules?
You can change the size and thickness of the by going to Simple Marker item (last item at the bottom of each of the ‘Marker line’ hierarchies) and playing with ‘Size’, ‘Colors’ and ;Outline width’ etc to make it look how you want.
