Ocular Micrometer

 

a built-in micrometer in the eyepiece (ocular) of a microscope, geodetic instrument, or astronomical instrument. It is used for exact measurements of small linear and angular distances and for increasing the accuracy of sighting in theodolites. A filar micrometer is most often used as an ocular micrometer.

Beetle abdomens were macerated, and free sporophorous vesicles were examined under phase contrast microscopy at 400x magnification and measured with a calibrated ocular micrometer (n = 125).
Measurements were carried out using an ocular micrometer in a stereoscopic microscope at a magnification of 15X.
Without the use of an ocular micrometer, oocysts of Cyclospora might be easily confused with those of Cryptosporidium or other fecal artifacts that stain acid-fast positive, as was the case in a pseudo-outbreak of cyclosporiasis reported in Florida (6).
