Introducing the DiffractoStep-RV1: A New Standard in Fast and Affordable Thin Film Thickness Measurement
Vac Coat Ltd. is proud to introduce the DiffractoStep-RV1, an innovative laboratory instrument that delivers rapid, accurate, and non-contact thin film thickness measurement using the unique principle of Fresnel diffraction from an optical reflective phase step. Designed for researchers, thin-film laboratories, and quality control environments, the DiffractoStep-RV1 provides a practical alternative to conventional surface profilometers and high-cost optical interferometers for measuring deposited film thicknesses from 50 nm to 2 μm.
Unlike many conventional thickness measurement systems that rely on mechanical stylus contact, expensive interferometric optics, or time-consuming scanning procedures, the DiffractoStep-RV1 performs fully non-contact measurements within seconds with 2 nm measurement resolution, less than 2% variation in repeatability, and excellent measurement speed in a compact benchtop instrument.
The system has been engineered specifically for modern thin-film research and production. Its precision stepper-motor positioning and tilt alignment, high-resolution Basler camera, and dedicated step holder enable highly repeatable measurements while simplifying sample preparation. Researchers can quickly verify deposition thickness, calibrate coating systems, validate reference standards, and perform routine process control without the complexity and maintenance associated with many traditional systems, offering laboratories an efficient solution for routine thin-film metrology.
Whether used alongside sputtering, evaporation, or other physical vapor deposition systems, DiffractoStep-RV1 enables reliable thickness verification while significantly reducing the investment typically required for precision optical thickness measurement. The DiffractoStep-RV1 reflects Vac Coat's commitment to making advanced thin-film characterization more accessible, practical, and cost-effective for research and industrial laboratories worldwide.
