ECOGRAB: Desarrollo de un sistema industrial de grabación de redes de difracción/polarización para su aplicación en encóderes con láser de femtosegundos

ECOGRAB Project, under the funding program RETOS-Colaboración (RTC-2016-5277-5) and developed by Fagor Automation, Universidad Complutense de Madrid, Centro de Estudios e Investigaciones Técnicas de Gipuzkoa (CEIT), Snelloptics and CD6 UPC, is focused on replace a manufacturing system for linear encoders that intensively uses chemical products through a cleaner and more efficient manufacturing system. In this framework, an optical system containing a slit has been designed and its use has been validated for the ablation of a strip material by means of a femtosecond pulse laser with an objective size of 3mmx5μm
