Calibration Overview SEM Calibration Overview
Tin spheres on carbon a very useful for SEM, FESEM, FIB astigmatism correction due to their nearly perfect round shape. Tin on carbon is also used instead of gold on carbon where gold is not allowed in the SEM, FESEM or FIB, such as in semiconductor applications. The round tin spheres are particularly useful for testing image quality, distortion, contrast, brightness and probe size. Available in three versions for low, medium and high magnifications.
See the PELCO® SEM Sample Stub Vacuum Desiccator to protect your test specimen when mounted on a tin stub.
Dispersion of tin spheres on a carbon substrate that is 6.15mm diameter x 2.2mm thickness. Approximate size range of <20 - 400nm. Spherical shape ideal for astigmatism correction. Wide particle size range with larger spheres that are easier to use at low kV. Recommended for SEM, FESEM, and FIB in the semiconductor industry where gold on carbon cannot be tolerated. Available unmounted or mounted on a specimen stub of your choice.
