Lynn M. and Valerie J. Barker
Co-Founders of Valyn International

Lynn and Val Barker formed Valyn International in 1990, designing, developing, and marketing instrumentation for those studying Shock Waves in Condensed Materials.

Their most important product, the VALYN VISAR, was developed in late 1994. It was an immediate success, and has evolved into a family of VALYN VISARS, i.e. the CLASSIC, the DOUBLE-DUTY ORB, and the MULTI-BEAM VISARs, which are used world wide.

Lynn and Val are semi-retired, but still do consulting work in shock compression science.
