Web3 Mark s. Fig. 2.1 shows a diagram of a stage micrometer scale that is being used to calibrate an eyepiece graticule. One division, on either the stage micrometer scale or the eyepiece graticule, is the distance between two adjacent lines. The length of one division on this stage micrometer is 0.1 mm.

WebThe graticule has a scale ruled on it. You must find out the distance measured for each division of the graticule. You can then use the graticule to measure cells. The distance will be different for each objective. To do this, you will use a stage micrometer.

With microscopy it is important to know how big the object is that you are imaging. The simplest way to do this is to use a stage micrometer (also called a graticle or graticule). These are small rulers and designed to be imaged using the same optics setup as being ... WebThe graticule fits inside the eyepiece on top of the field restrictor. In a fancy setup, one uses a focusing eyepiece, where the distance between the front lens and the graticule can be adjusted for focusing, but in practice, unless one's vision is abnormal, there is normally enough thread on the front lens component to afford adequate focusing with a standard … lady\\u0027s-eardrop r8
