Stents are small tube made of plastic or metal which are inserted within blood vessels to prevent constriction. These stents are treated with a polymer or drug coating to enhance functionality and corrosion-resistance. Using F40 instrument along with 20x objective (25µm spot size), it is able to measure the thickness of these coatings along the outer diameter of a stainless-steel stent. The powerful instrument system is capable of fast and reliable thickness measurements that is non-destructive and requires no sample preparation.
