If you want to make measurements on your microscope you will need to calibrate it. The One Stop Nature Shop has the largest range of specialist microscopy calibration scales backed by expert advice.
Micrometer Slides (also known as Stage Graticules, Stage Micrometers and Calibration Slides) are generally standard microscope slides with scales & patterns etched or printed on them.
The scales come in a huge variety of sizes, subdivision accuracies and patterns. The slides are typically 76x25mm standard size and made of glass (for bottom illuminated microscopes) or of polished metal (for reflected light materials/metallurgical microscopes). If you cannot find anything here we can obtain it for you, please ask. These slides are used to calibrate microscopes so measurements can be made.
To make measurements or to perform particle sizing on your microscope without a suitable Microscope Camera System you will need an Eyepiece Reticle as well as a Micrometer Slide
Eyepiece Reticles are similar scales placed in eyepieces. The reticles are available not only as scales of different sizes and orientations but also in additional patterns such as counting grids and particle sizes. Reticles come in a variety of sizes dependant on the eyepiece diameter - not all eyepieces can have them fitted. It is best usually to use a specialist 'focussing' eyepiece to ensure that the subject and the scale are both in focus at the same time. Fitting to existing eyepiecesrequires the presence of a retaining ring and an absolutely precise measurement of the inner diameter of the eyepiece where the reticle is to be fitted. Many of the Reticles we show are already pre-fitted into specialist focussing eyepieces, these are suitable for GX Microscopes microscopes, any monocular microscopes and other microscopes if supplied with a matching standard eyepiece for binocular viewing.
To perform counting of objects such as cells on your microscope without a suitable Microscope Camera System you will need either:
1. an Eyepiece Reticle with a counting grid and Micrometer Slide (so the grid can be calibrated) or
2. a specialist Micrometer Slide with a Counting Grid and usually a special coverglass.
Please ask for advice, we can provide almost any eyepiece reticle of any size. See our product range below:
