We will be exhibiting at Photonics Innovation 2026, which will be held at Pacifico Yokohama from November 10 (Tuesday) to November 12 (Thursday), 2026.

High-precision simulations recognized by researchers worldwide. Provides powerful support for “extreme film design” in laser optics, semiconductors, and advanced optical device development.

"TFCalc" is a product that calculates the properties of optical thin film coatings formed on insulators and metals. It can simulate reflectance, transmittance, absorbance, electric field, and color. It can handle coating layers of up to 5000 layers, allowing for the design of coatings suitable for special applications. Please feel free to contact us when you need assistance. 【Main Features (Partial)】 ■ Thin Films - Up to 5000 layers can be set on the front and back of the substrate. ■ Analysis - Calculation of reflectance, transmittance, absorbance, optical density, loss, phase difference, psi, and electric field intensity. ■ Optimization - Supports three methods: variable metric method, gradient method, and simplex method. *For more details, please download the PDF or feel free to contact us.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

The pinhole inspection for packaging engineering is fully automated, eliminating packaging defects based on certain quality standards. The judgment results and operational status can be managed via a monitor screen. - Quantitative management of quality standards for the pinhole inspection process - Ensuring the quality of the product's shelf life - Establishing evaluation criteria for the manufacturing process, achieving quantitative quality assurance - Slim and space-saving design that can be connected to existing production lines - Quick changeover for product variety switching can be handled in a short time by exchanging chambers - Fully domestically produced, allowing for rapid maintenance and troubleshooting - Example target works: pillow packaging, packaged rice (packaged cooked rice), etc. *Please consult us regarding the use of this product for pharmaceuticals.
