A wide range of non-contact surface measurement devices. Schmitt designs and manufactures a range of precision surface measurement and alignment products, that cover the diverse needs of the market - both domestic and international.
All smooth surfaces possess some degree of microroughness, even if only at the atomic level.
In high-technology products, roughness arises from the manufacturing process, which may involve chemical deposition, grinding, polishing, etching or several other commonly used production techniques. Schmitt engineers are harnessing this revolutionary technology within a series of products that conduct non-contact surface measurements for particular industry applications. Computer hard disks require exact manufacturing control and they have a narrow tolerance band for acceptable roughness. A cushion of air is all that prevents contact between the head and the disk surface. If the disk is too rough, the head will fly too far from the disk surface, causing a reduction in data density or storage capacity on the drive.
