The measuring scale is located in the field diaphragm plane, with 0.1 mm divisions. The eyepiece with a measuring scale is installed in place of a standard 10x eyepiece. A paired eyepiece without a measuring scale is installed in the second eyepiece tube.\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003eThe eyepiece is compatible with microscopes that have a 30 mm eyepiece tube.\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003e\u003cstrong\u003ePreparation\u003c\/strong\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003eBefore taking measurements, the eyepiece’s measuring scale must be calibrated for each objective to be used. A calibration slide is required for this: a stage micrometer with a scale. The minimum division is 0.01 mm. The calibration slide should be placed on the stage and the microscope focused on the measuring scale. The eyepiece should be rotated in the eyepiece tube until the stage and eyepiece scales are aligned in parallel.\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003e\u003cstrong\u003e\u003cspan lang=\"ES\"\u003eCalculating the value of the eyepiece’s integrated scale increment for each objective\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003e\u003cspan lang=\"ES\"\u003eIf you are using low magnification objectives, you should calculate how many divisions of the eyepiece’s integrated scale fit within the stage micrometer's scale.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003e\u003cspan lang=\"ES\"\u003eIf you are using medium and high magnification objectives, you should calculate how many divisions of the stage micrometer's scale fit within the eyepiece’s scale.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003eThe calculation for each objective is performed according to the formula:\u003cbr\u003eE=TL\/A, where\u003cbr\u003eE – eyepiece division value\u003cbr\u003eT – stage division value specified in the stage micrometer (0.01 mm)\u003cbr\u003eL – number of stage micrometer divisions\u003cbr\u003eA – number of eyepiece scale divisions.\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003eThe resulting values from calculating the eyepiece’s scale division for each objective should be noted.\u003c\/p\u003e\u003cp class=\"MsoNormalCxSpMiddle\"\u003e\u003cstrong\u003eCalculating the true linear size of an object\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003eWhen measuring an object, you must first count the number of eyepiece scale divisions that the object spans.
