FilmScatter is optical thin-film software from Poggi Software, positioned for calculating the optical properties of multilayer film stacks. Rather than being a general-purpose developer tool, it is a specialized simulation tool for optical engineering and research. It can calculate specular reflection, transmission, and absorption, as well as scattering behavior caused by rough surfaces and in-layer inhomogeneities.
Based on the page content, FilmScatter includes modules such as Specular, Surface Scattering, Volume Scattering, Guided Modes, and a materials database. Specular handles R/T/A calculations for thin-film stacks; Surface Scattering can calculate BRDF·cosθ and TIS from rough surfaces, and mentions the use of three vector scattering theories; Volume Scattering focuses on inhomogeneities within individual layers; Guided Modes uses numerical methods to solve the effective refractive index of guided modes in multilayer structures, which may be real or complex. The materials database supports viewing the Cauchy dispersion relation for glasses.
The software uses a Windows desktop interface, and the text states that it was developed in C++ under Microsoft Visual Studio 2013. For integration, FilmScatter supports XML import and export, and explicitly mentions data exchange with software such as OPTILAYER. Results can also be exported to Microsoft Excel for further analysis and reporting. The website provides modular introductions and Learn more/Read more entry points, but the captured content does not show information about an API, SDK, command-line batch processing, script automation, or a complete technical manual.
The text does not disclose pricing, licensing, trials, payment methods, or the purchase process, nor does it state whether the software is open source. Self-hosting is not applicable to this type of professional desktop software, and the page does not mention cloud deployment. Availability from China, payment accessibility, and local technical support cannot be determined from the text.
Its strengths are its focused feature set, covering specialized thin-film optics topics such as specular behavior, surface scattering, volume scattering, and guided modes, along with support for data workflows involving OPTILAYER and Excel. Its limitations are the relatively limited public information, version activity that appears to date back to an earlier period, a technical stack and interface that may feel traditional, and unclear automation or developer-integration capabilities. It is best suited to engineers and researchers working on coating design, optical thin-film scattering analysis, and multilayer film research. If you need a modern API, cloud collaboration, or a cross-platform development workflow, you should verify further or consider other thin-film design software.
