The EUV beam splitter boasts a high reflectivity for extreme ultraviolet light (>70%) while maintaining a high transmission rate for infrared light (>65%). Its primary function is to filter out the majority of the high-energy, fundamental frequency, femtosecond infrared light from the emitted beam. Composed of dual electric motor modules and an EUV camera feedback unit, it leverages an in-house developed algorithm for EUV beam pointing stabilization, thereby enabling the stable pointing and locking of the EUV beam.
