HULINKS to release TFCalc V5.0 with new interface and 3D plots

HULINKS will launch TFCalc V5.0 on Oct. 27, 2026, adding a redesigned interface, new analysis tools and 64-bit architecture to its thin-film design software. The update targets researchers and engineers who need faster modeling, clearer visualization and easier workflows for optical coating design.

Why it matters: - TFCalc is used for optical thin-film coating design, analysis and optimization in academic and corporate R&D. - The V5.0 update is designed to make simulation review, material selection and design iteration faster as optical devices become more complex. - HULINKS is also adding academic pricing to widen access for universities, technical colleges and public research institutions.

What happened: - HULINKS announced TFCalc V5.0 on Oct. 20, 2026, with release set for Oct. 27, 2026. - TFCalc V5.0 is a major update from TFCalc V3.6. - The software will be available alongside TFCalc V3.6. - TFCalc V5.0 can read and save files in the TFCalc V3.6 format.

The details: - TFCalc calculates reflectance, transmittance, absorptance, phase shift, electric field and color for dielectric and metallic coatings. - The software supports coating designs with up to 5,000 layers. - HULINKS said the new version keeps the established calculation methods and numerical behavior of the previous version while improving analysis and visualization. - The interface now uses a Multi-Document Interface, letting users manage multiple designs in one parent window. - Tabular editing now supports direct cell entry, range selection, auto-fill, copy and paste with external software, and full undo and redo history. - The UI is available in English and Japanese. - New 3D surface plots show spectral characteristics across wavelength and incident angle. - The 3D tools support rotation, zoom, pan, cross-sectional views, image export, printing and clipboard copying. - 2D plots now include color-coded saved results and real-time coordinate display at the mouse cursor. - Users can add custom reference lines to plots. - Color charts now render in full color, with an option to switch back to monochrome. - Material filtering lets users search databases by target wavelength and by refractive index or extinction coefficient. - The application has moved to a 64-bit architecture for more stable memory-intensive processing. - Users can choose between speed-priority and accuracy-priority calculation modes. - Speed-priority mode is aimed at exploratory design work. - Accuracy-priority mode is aimed at final validation. - TFCalc V5.0 supports Windows 11. - 3D plotting requires a graphics environment that supports OpenGL 3.2 or later. - Commercial pricing is set at $1,650 per license. - Upgrade pricing is available for existing V3.5 and V3.6 users. - Academic pricing is available for eligible faculty, researchers and students at universities, technical colleges and public research institutions. - Academic users must register with an institution-issued email address and submit student ID or proof of affiliation. - Evaluation licenses are available through HULINKS’ demo request form, which asks users to mention “V5 Request” in the comments field. - The company’s current product page is available at Product page. - Evaluation requests can be submitted through the demo request form.

Between the lines: - The redesign points to a push to modernize a long-established scientific tool without changing its core calculation behavior. - Bilingual support, spreadsheet-style editing and multi-window design management suggest HULINKS is targeting power users who want faster iteration and lower friction. - The 64-bit migration and dual calculation modes also signal an attempt to serve both early-stage exploration and final verification in one workflow.

What's next: - The official TFCalc V5.0 product page will go live on the release date. - HULINKS is expected to begin sales, upgrades and academic licensing when the software launches on Oct. 27, 2026.

The bottom line: - TFCalc V5.0 is a substantial refresh of a niche engineering tool, pairing a modern interface with compatibility, faster visualization and new academic pricing.
