Eyepiece with graduated scale MAGUS MES10 10х/22 mm (D 30 mm) - MAGUS

This eyepiece is equipped with a graduated scale positioned on the plane of the field diaphragm for measuring samples in millimeters or microns. The scale division is 0.1 mm. It is housed in an optical tube with a 30 mm barrel instead of a classic eyepiece with 10x magnification. When you change lenses, you need to recalibrate the graduated scale. To do this, you need a calibration slide (a micrometer object) with a 0.01 mm scale. The slide is placed on the microscope stage and the eyepiece is rotated in the optical tube until the scale of the eyepiece and that of the slide become parallel.

Moreover, for each objective the division value is decisive of the eyepiece scale. For low magnification objectives, it is necessary to count the number of divisions of the eyepiece scale that are within the scale of the calibration slide. For medium and high magnification objectives, however, the opposite must be done: you need to count how many divisions of the slide scale are included in the eyepiece scale.

Therefore, the value of the division (E) it is calculated according to the formula: E=TL/A, where: T – is the value of the division of the micrometric scale of the slide (0.01 mm); L – is the number of divisions of the slide scale; A – is the number of divisions of the eyepiece scale.

To calculate the effective linear dimension of a sample, therefore, the length of the sample must be measured in the eyepiece scale and then multiply this value by the E factor calculated according to the objective in use.
