The Company is engaged in the development, marketing and manufacturing of detection, sensing and analysis technology and optical components as well as contract research. Its products and services are used in application markets including the homeland security, industrial and medical markets sectors. The products and services are sold throughout the United States and internationally. The Company has three reporting segments: Contract Research; Optic; Biomedical; and Instruments. Contract Research segment's business unit, RMD, is among the business participants in U.S. government-funded research, performing research and development activities for government agencies including Department of Energy, Department of Defense, Department of Homeland Security, Domestic Nuclear Detection Office, National Institutes of Health and NASA. RMD develops technology in materials, sensors and prototype instruments that detect or measure radiation, light, magnetism or sound for use in security, medical and industrial applications. RMD has research expertise in material science, radiation detection, digital imaging technology, magnetic imaging, laser optics and photonics. The Optical Technology segment is engaged in the production of optical materials, components and coatings for various applications in the medical, industrial, and homeland security/defense sectors. The Optics segment supplies synthetic crystals, optical materials, components, and coatings that are used in devices such as baggage scanners, medical imaging systems, optical instruments, lasers, analytical instruments, automotive components, semiconductor/electronic devices, spacecraft/aircraft components and advertising displays. These products are offered through four business units (Dynasil Fused Silica, Optometrics, Hilger and EMF). The Biomedical segments product candidate Xcede is a resorbable hemostatic patch to be used when conventional techniques are inadequate or impractical during general or cardiovascular surgery. RMD's competitors include other small high technology companies performing SBIR R&D, large firms such as Raytheon which performs related R&D, universities and national laboratories. The optical segment competes for business with fabricators of industrial optical materials, other optical components manufacturers, other optical crystal manufacturers and other optical coaters as well as other analytical instruments manufacturers and synthetic crystal manufacturers.
