Diffusion glass "IOP series" that enables uniform light diffusion and transmittance adjustment.

【Product Introduction: IOP Series】 This is a diffusion glass that uniformly diffuses incident light and has characteristics close to a Lambertian light source. The milky white color is due to the glass itself, not an opal coating. It has higher diffusivity than frosted glass. A feature of this product is that the spectral transmittance can be adjusted by changing the thickness. 【Features】 ■ Uniform diffusion glass close to a Lambertian light source ■ Higher diffusivity than frosted glass diffusion plates ■ Transmittance can be adjusted by modifying thickness and manufacturing conditions ■ Ideal for optical applications in machine vision, LED lighting, and observation systems

FTIR is a highly versatile analytical technique that can be used for the identification, quantification, and structural analysis of various organic compounds. It allows for relatively quick and easy measurement results, making it applicable in a wide range of fields such as research and development and quality control. By effectively utilizing FTIR, it is possible to conduct organic analysis more efficiently. This webinar will clearly explain the essential foundational knowledge needed to utilize FTIR. It is recommended for those currently using FTIR, as well as those considering its introduction or who are interested in it. <Program> "Basics of FTIR" Fourier Transform Infrared (FTIR) spectroscopy is a general analytical method that can perform qualitative and quantitative analysis on a wide range of organic compounds. By combining it with various measurement techniques, it is possible to measure samples in solid, liquid, and gas forms. To effectively utilize FTIR, it is important to understand the basics, which enables diverse applications in analysis. Therefore, this webinar will focus on introducing foundational content such as the principles of hardware and the basic principles of various measurement techniques.

We will solve the issues related to the deterioration of defect rates due to fine particles and the need for cleanliness in manufacturing sites. The particle visualization system developed by Shin Nippon Air Technologies, under the ViEST brand, combines a uniquely developed ultra-sensitive camera and light source to visualize fine particles in clean rooms and equipment. It can capture their behavior in real-time while also quantifying particle information, making it a world-class visualization system. Currently, we are expanding the sale of systems and tools, as well as contract technical services utilizing these technologies both domestically and internationally. We have particularly rich experience in the semiconductor industry and clean rooms. The following are some examples of applications, but by utilizing our technology, we can strongly promote solutions to various issues such as the deterioration of defect rates caused by fine foreign substances, visualization of clean airflow, and concerns regarding cleanliness in the field. - Visualization investigation of fine particles and airflow in manufacturing lines and environmental improvement - Promotion of cleanliness in manufacturing equipment and environments - Cleanliness evaluation of various equipment performance - Improvement of yield and quality degradation caused by contamination issues - Support for research and development requiring visualization of fine particles and airflow - Evaluation of particle generation from products.

In order to aim for a speedy resolution of business challenges from a multifaceted perspective, it is essential to create an environment where various data can be aggregated in one place and analyzed integratively.
