公司建立之初是為現階段的空間儀表提供高性能、高穩定性、體積小以及低功耗的儀器和部件。隨后，公司的混合前置放大器成為航天工業的配置標準，并在全球范圍內用于地表衛星和外層空間探測器。Amptek已經開發出一系列產品如等離子分析器、電子離子探測器以及輻射監控器等，這些產品被廣泛用于軍事、科研和商貿等領域。
Amptek is a high technology company and a recognized world leader in the design and manufacture of state-of-the-art nuclear instrumentation for the satellite, x-ray and gamma ray detection, laboratory, analytical, and portable instrumentation industries.

Background
Amptek was founded in 1977 by Alan C. Huber and John A. Pantazis to fulfill the needs of space instrumentation for off-the-shelf, high performance, high reliability, small size and low power dissipation instruments and components. Shortly thereafter, Amptek hybrid preamplifiers became the standard for the space industry as they were used worldwide by instrument makers in both Earth satellites and deep space probes. Numerous plasma analyzers, electron and ion detectors, and radiation monitors have been developed by Amptek and flown in both military, research, and commercial spacecraft.
