Measurements with a micrometer microscope slide preparations
August 10, 2010
Posting articles about measurement with a micrometer has been little discussed previously , and on this occasion I tried to explain again as follows.
To calibrate the measuring scale on the microscope there are two scales used, the scale of the ocular (eyepiece placed) and the objective scale (which was placed on the table objects). In principles ocular scale is scale of 1-100, where the distance between the lines the same but unknown value. While the objective is to scale on a scale of 1-100, where the distance between the lines has a value of 0.01 mm. Ocular scale has not changed in size although the objective magnification changed while the scale is changed in size when the magnification is changed. Therefore, the calibration is done so that the ocular scale has a value of an objective scale parbandingan with ocular scale at every magnification.
Example Calibration:
Both the scale of objective and ocular scale placed coincide with each other, after it was seen where the most coincide lines from left to right. Setelah itu di hitung berapa sekala okuler dan berapa sekala objektifnya dengan rumus SKALA OBJEKTIF/SKALA OKULER. After that the count how many and how much scale scale ocular objective with a formula OBJECTIVE SCALE / SCALE Ocular.
