Segment Reporting Disclosure [Text Block] | Note 10 Segment, Customer and Geographical Reporting Segment Financial Information Dynasil reports three reportable segments: contract research (“Contract Research”), optics (“Optics”) and biomedical (“Biomedical”). Within these segments, there is a segregation of operating segments based upon the organizational structure used to evaluate performance and make decisions on resource allocation, as well as availability and materiality of separate financial results consistent with that structure. The Optics segment aggregates four operating segments Dynasil Fused Silica, Optometrics, Hilger Crystals (“Hilger”), and Evaporated Metal Films that manufacture commercial products, including optical crystals for sensing in the security and medical imaging markets, as well as optical components, optical coatings and optical materials for scientific instrumentation and other applications. The Contract Research segment is one of the largest small business participants in U.S. government-funded research. The Biomedical segment consists of a single operating segment, Dynasil Biomedical Corporation (“Dynasil Biomedical”), a medical technology incubator which owns rights to certain early stage medical technologies. Dynasil Biomedical holds common and preferred stock in the Xcede joint venture which is developing a tissue sealant technology and currently has no other operations.
