Description
These microscope micrometers are measuring Instruments which are used to measure the length of microorganisms, cells, or other tiny objects. They must be placed in a microscope for measurement. Microscope micrometers are classified into eyepiece micrometers and objective micrometers. These microscope micrometers are commonly used testing equipments and Instruments in the food industry and microbiological research fields.

The eyepiece micrometer: is a circular piece of glass which is placed in the eyepiece of the microscope. As shown in the picture of the eyepiece micrometer of microscope, the center is engraved with a precise scale. Usually divide 5mm into 50 grids, and the actual grid is equal to 100μm. The size of the scale changes with the magnification of the eyepiece and objective used. It must be calibrated with the objective micrometer before using.

The objective micrometer: is called the stage micrometer. It is a special glass slide that is placed on the stage of microscope. As shown in the microscope objective micrometer picture below, there is a small circle in the center. The circle is engraved with a scale, and the line of 1 mm in length is divided equally into 100 small cells, and each small cell is equal to 10μm. The lower part of the figure, below C1, is an enlarged view of the scale inside the circle. The scale inside the circle is the standard length which is used to calibrate the eyepiece micrometer.

Parameters of Microscope Micrometer
* Parameters of microscope eyepiece micrometer
(1) Lens diameter: There are 10 types, respectively φ20.4mm, φ21mm, φ22mm, φ23mm, φ24mm, φ25mm, φ26mm, φ27mm, φ28mm, φ29mm.
(2) Lens thickness: 1.5mm
(3) Ruler: As shown on the right, the ruler consists of two rulers, vertical and horizontal. Form a "cross shape." Each ruler has 100 scales of which each value is 0.1 mm, with a total length of 10 mm, and the lines extend to the edge of the slide.
(4) Material: It is made of glass with high transmittance by laser engraving.

* Parameters of microscope objective micrometer
(1) The microscope objective micrometer is a combined micrometer with three sets of scales. As shown in the figure below, from left to right, the first pattern is a tick mark of 10 mm total length, divided into 100 equal parts, each aliquot is 0.1mm. In the middle is the pattern of the C1 type micrometer that we usually use, 0.01mm per scale. The third pattern has a total length of 5 mm and is divided into 100 equal parts, and each aliquot is 0.05mm. The combined micrometer sets 0.1mm and 0.01mm and 0.05mm in one, it´s convenient and practical.
(2) Lens size (length × width × thickness): 75mm×25mm×1mm
(3) Graphics accuracy: 1μm
(4) Material: It is made of glass with high transmittance by laser engraving.
