SEM Resolution Test Specimens; Tin on Carbon
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.
Dispersion of tin spheres, the majority being within the size range of 10nm to 100nm, on a carbon substrate that is ø6mm x 0.5mm. Ideal for astigmatism correction and resolution determination. Recommended for SEM, FESEM, and FIB in the semiconductor industry where gold on carbon cannot be tolerated. This standard is available unmounted or mounted on a specimen stub of your choice.
