In the field of optoelectronics, vacuum conditions and efficient electron and light emission are vital for the operation of electrical-to-optical and optical-to-electrical transducers. SAES provides advanced porous getters for many electronics applications, as well as dispenser cathodes for all types of X-ray tubes used in medical, testing, security and scientific applications.

Small cathodes, submounts, heatsinks, and getters made from a variety of SAES proprietary alloys also contribute to enhancing the performance of ion gas and other types of lasers. For night vision systems and infrared cameras, SAES alkali metal dispensers and getters ensure lifelong reliable vision in civilian, defense, and security applications.
