Celestron Microscope Calibration Slide

This Celestron Microscope Calibration Slide, also known as a stage micrometer, is essential for calibrating a microscope camera or imager, whether a digital microscope or a manual one with a digital imager attachment. It can also be used for manual measurements of tiny things such as microfibers or for determining the field of view of different eyepiece/objective lens combinations. Its 1mm ruler is subdivided into 0.01mm markings. The 1 x 3" calibration slide fits easily on standard microscope stages.
