What each letter means
| Quantity | Unit |
|---|---|
| Length of one eyepiece division | µm |
| Stage micrometer length lined up | µm |
| Eyepiece divisions lined up | no unit |
Worked example
Find the length of one eyepiece division when Stage micrometer length lined up = 100 µm, Eyepiece divisions lined up = 40.
Using one division = (stage micrometer length)/(eyepiece divisions): Length of one eyepiece division = 2.5 µm.
Frequently asked questions
What is the formula for Eyepiece graticule calibration?
one division = (stage micrometer length)/(eyepiece divisions).
What do the letters stand for, and what units are used?
Length of one eyepiece division in µm, Stage micrometer length lined up in µm, Eyepiece divisions lined up.
How do you calculate length of one eyepiece division?
Put the values into one division = (stage micrometer length)/(eyepiece divisions). For example, with Stage micrometer length lined up = 100 µm, Eyepiece divisions lined up = 40, length of one eyepiece division = 2.5 µm.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (length of one eyepiece division, stage micrometer length lined up, eyepiece divisions lined up) and fill in the others: it rearranges the formula for you.
