Virial International (formerly Virial, Inc.) is a small business headquarted in Gaithersburg, Maryland. Virial, Inc. was founded in June 2000 in New York, NY and became a Maryland limited liability company in 2011. Virial International is the only company offering specialized software and services for companies and organizations working in optical radiometry, radiation thermometry and adjacent areas.
Virial, Inc. was the creator of STEEP3 code intended for numerical modeling of radiation characteristics of blackbody radiation sources. Since 2000, STEEP3 became the de facto standard in calculations of the effective emissivity of blackbodies for calibration laboratories and remote sensing applications. This program is based on the proprietary Monte Calo algorithm and used in national metrological centers of USA, UK, Germany, Canada, Japan, France, the Netherlands, Russia, Spain, Finland, South Korea, China, Taiwan, and others. We have STEEP3 (and its successors) customers in NASA, Space Dynamics Laboratory (Logan, UT), Space Science and Engineering Center (University of Wisconsin-Madison), Sub-department of Atmospheric, Oceanic and Planetary Physics (Department of Physics, University of Oxford, UK), and in world-leading high-tech companies. Currently, Virial International offers a range of programs for calculation of radiation characteristics of blackbody radiation sources as well as all-purpose radiometric software.
If you are looking for a specialized software for optical radiometry and radiation thermometry, only Virial International has what you need. You can download evaluation versions of our software and detailed manuals for free.
Virial International offers various services for the optical radiometry community. We will help you to choose geometry and materials for optical radiation sources, detectors, and other measurement equipment, such as blackbody radiation sources, various detectors of optical radiation, radiometers, spectroradiometers, integrating spheres, scatterometers, emissometers, etc.; perform steady-state and transient thermal modeling; fulfill customers' orders for performing calculations, development of new and customization of the existing software.
Virial International provides contract engineering to scientific and Hi-Tech customers for development of new ideas, designs and comprehensive assessments of innovative technical concepts. We provides expert advice and assistance based on the extensive skills and unique experience of Virial's founder, Dr. Alexander Prokhorov, in all questions concerning optical radiometry, photometry, radiation thermometry, and radiative heat transfer.
We invite our visitors to explore www.virial.com and see for yourself why customers have permanently turned to our software and services for the past 10 years.
