How do you calibrate the ocular micrometer? |
1) place the stage micrometer scale slide on the stage. 2) using the mechanical stage controls, line up the left hand zero end of the scale with the left hand zero end of the 2 mm stage scale. 3)measure the length of the entire ocular scale on the scanning objective lens, the low power objective lens, the high power objective lens but not the oil immersion lens. 4)now you can use the ocular scale to measure the dimensions of the specimens you examine 5)simply line up the image of the specimen with the ocular scale by using the mechanical stage or by rotating the eye piece that holds the ocular scale. Then count the number of ocular units along the dimension of the specimen and multiply the value by the ocular unit for that particular power... For example... If the object appears to be at 2 o u long when you observe it on high power, and if yourcalibration showed 100u to be equal to 25 micrometers on high power, then the objects length is 2 o u x 25 micro meters or fifty micrometers long. |
