| micrometre disk | <microscopy> A glass disk engraved with a suitable scale, used at the diaphragm of a micrometre ocular. The scale to be focused by the eye lens has to be seen in the field of view. Micrometre eye piece. (05 Aug 1998) |
| stage micrometre | <microscopy> A graduated scale used as a standard on the stage of a light microscope for calibrating an eyepiece micrometre, also for determining the magnification of a set-up in photomicrography, etc. (05 Aug 1998) |
|---|---|
| filar micrometre | <microscopy> An eyepiece equipped with a fiducial line in its focal plane that is movable by means of a calibrated micrometre screw in order to make accurate measurements of length. Synonym: filar eyepiece. (05 Aug 1998) |
| filar micrometre ocular | <microscopy> A micrometre ocular with crossed lines which can be simultaneously focused in and moved across the field by means of a micrometre screw. The amount of displacement can be read in 0.01 steps on the micrometre drum head. This makes a very delicate measuring device, since calibration of the micrometre scale by means of a stage micrometre gives values for each interval on the drum head which are much less than the resolving power of the highest-aperture objectives.
