Joaquin B. Agony, nippy S. Beanie (14 August 2014) (21 August 2014) l. Introduction Microscopes and the field of Science argon two inseparable things. Almost all Sciences ar associated with the use of a microscope, a device use to view objects which are not obvious to the naked eye. The term microscope came from the Greek term Micros which means small and utter which means to examine (Vocabulary. Com, 2014).Today, microscopes are of great importance especially on the field of Biological Science. One of its major use is to determine the sizes of microorganisms which are of great importance in understanding certain biological phenomena. acquiring the actual size of microscopic objects such as microorganisms using calibrate eyepiece micron is termed micrometer (Echoic, et. Al. , 2000). It is important for investigators across a spot of disciplines. A biologist, for example, needs to know the exact size of two organisms to bear an intelligent comparison (I. E.Almoner). The intent of this activity is to create an awareness in proper handling techniques ND correct use of a microscope to students act courses in the field of Biological Sciences. This activity is also intended to hear students microscope calibration techniques. II. Materials and Methods To able to obtain the exact measurement of a specimen, the eyepiece micrometer should be calibrated first. By doing so, the calibration everlasting (C) is obtained. To imbibe the calibration constant, a stage micrometer, an eyepiece micrometer and a microscope is used.The ocular micrometer was placed inside the ocular lens of the eye of the microscope and the stage micrometer on the stage. The field was adjusted so that a line in the ocular micrometer is superimposing a line in the stage micrometer. formerly this was set, the n coffee tree of divisions in both micrometers from the first superimposing lines to the next line that superimpose was counted. The number of divisions in the stage micrometer was divided by the divisions in the ocular micrometer. The quotient was cipher by pm.The product obtained was the calibration constant. The calibration constant was determined in each of the objective lenses of the microscope. Once the ocular micrometer was calibrated, the pessimism were viewed and measured. The correct measurement was obtained by counting the ocular micrometer divisions occupied by the specimen and multiplying it by the calibration constant of the objective lens used. The deviation between the measurement should only appear on the quantitative places of the figure. Ill. Results and Discussion Table 1. Calibration Constant Under Different Microscope object Lenses Table 1. 0 shows the summary for the computed calibration constant under the postgraduate power objective (HOP) and the the low power objective (LOOP). Under the HOP, the umber of divisions in the ocular micrometer between the two superimposing lines is four eyepatch on the stage micrometer it is five. Di viding five by four, the value 1. 25 is obtained. This is not yet the calibration constant. The value 1. 25 should be multiplied by pm to get the C.
