L-Ray technology offers true-thickness quality control for thin materials, utilizing infrared radiation for precise and non-contact measurement. This technology is ideal for both opaque and transparent or translucent materials, providing the smallest-achievable measuring spot. Depending on the application, we choose either laser-based L-Ray technology or confocal-based L-Ray technology.
Laser-based L-Ray technology uses laser sensors to measure material thickness. In a differential setup, two lasers are positioned on opposite sides of the material—one on top and one underneath. They work together to measure thickness accurately. In a single-sided setup, one laser sensor measures the material guided over an additional roll. This setup is tailored to specific applications, whether for long range, high precision, or different surface types.
Confocal-based L-Ray technology is used for materials where laser-based methods aren't suitable, such as battery films and steel products. It uses two confocal sensors, one above and one below the material, to measure thickness. For thin transparent films, only one sensor is needed on top. This method provides precise measurements for shiny or glossy materials.
L-Ray technology is particularly well-suited for the sheet metal industry due to its precision, non-contact measurement, and adaptability to various material types and thicknesses.
