Welcome to Virial International, LLC. This web site is an invaluable source of materials for both aspiring students and experts focused on theoretical and computational aspects of optical radiometry, photometry, and radiation thermometry. Read more about Virial International
If you are looking for specialized software and services for optical radiometry and radiation thermometry, you have come to the right place. Virial's modeling software will help you optimize your designs by simulating conditions that accurately replicate the parameters of your problem. You can download evaluation versions of our software as well as the accompanying detailed manuals and purchase our programs if they are suitable for your tasks.
In the event that our standardized software does not quite match your requirements, we would strive to develop software that is uniquely designed to fit your needs. In fact, customization of our existing software is one of our most popular services. You will receive exclusive usage rights for the uniquely tailored software, designed to help you further your goals - from planning, validation, and interpretation of your measurements to preparing papers for peer-reviewed journals or writing your Ph. D. thesis.
Virial International will also assist you in solving tasks that involve numerical analysis, computer modeling of radiometric devices or processing of measured data. Our services also include calculations on demand, new software development, scientific and engineering consulting, research and development, and information support for your R&D projects. Virial International has extensive experience in computer modeling of sources and detectors of optical radiation, integrating spheres of various purposes, reflectometers and gonioreflectometers, radiative heat transfer and optical properties of materials.
We are here to help you develop new ideas and innovative technical design concepts and evaluate uncertainty of radiometric measurements. We invite our visitors to explore Virial's annotated Project Portfolio which demonstrates the scope of our past projects .
Virial International is always open for mutually beneficial collaboration in the areas of joint scientific interests. We hope you will choose Virial International to be the trusted partner in your future scientific endeavors.

Information
Satori111 v. 1.1 is released.
Satori111 is the first program developed especially for calculation of parameters for the Sakuma-Hattori interpolation equation.
Satori111 can be used at radiometric temperature calibrations of radiation thermometers (pyrometers) and blackbody radiation sources by multiple-point method.
Calculation of Sakuma-Hattori parameters is performed using the Levenberg-Marquardt method then verified by the Particle Swarm Optimization.
Satori111 allows fitting the Sakuma-Hattori equation for up to 20 reference temperatures from 100 to 4000 K with the fitting error not exceeding 1 mK for narrow-band radiation thermometers and 100 mK for wide-band radiation thermometers.
After determination of the Sakuma-Hattori parameters, up to 1000 signals of the radiation thermometer can be converted into temperatures at once.
