We will exhibit at OPIE'21 (OPTICS PHOTONICS International Exhibition 2021) from June 30 to July 2, 2021.

High laser durability coatings such as "Laser Mirror (HR film)" and "Anti-Reflection Coating (AR film)" are available! We also offer measurements of laser damage thresholds!

We offer "Laser Mirrors (HR Coating)" and "Anti-Reflective Coatings (AR Coating)" as high-durability products for high-power lasers. Laser Mirror: A specially coated film optimized to achieve high reflectivity at specific laser wavelengths. Anti-Reflective Coating: A high-durability anti-reflective coating used in newly developed high-power laser devices. Laser Damage Threshold (LIDT) Measurement: Measuring the damage threshold by irradiating optical components with lasers. 【Features】 ■ Laser Mirror (HR Coating) High reflectivity of over 99.0% → Laser damage threshold of 122 J/cm² at a wavelength of 1064 nm → Laser damage threshold of 16.8 J/cm² at a wavelength of 355 nm ■ Anti-Reflective Coating (AR Coating) Ensures high durability → Laser damage threshold of 21.0 J/cm² at a wavelength of 532 nm ■ Advantages of Our Laser Damage Threshold (LIDT) Measurement 1: Ability to investigate damage thresholds, lifespan predictions, and defect densities 2: Capable of handling substrates from very small to large sizes 3: Possesses various types of lasers 【We will exhibit at OPIE'23 Laser EXPO】 April 19 (Wed) - 21 (Fri), 2023, 10:00 - 17:00 @ Pacifico Yokohama

Nitto Kohki will hold the "2024 Attack Fair in Ichihara" at the "Yume Hall" for two days from December 11 (Wednesday) to December 12 (Thursday), 2024. The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful souvenirs for visitors and many fun activities prepared. We look forward to welcoming everyone!

Nitto Kohki will hold the "2025 Attack Fair in Kurume" at the "Local Production Kurume General Exhibition Hall" for two days from February 13 (Thursday) to February 14 (Friday), 2025. The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful commemorative gifts for visitors and many fun activities prepared. We look forward to welcoming everyone!

**Seminar Overview** The construction industry faces many challenges, including a shortage of personnel, regulations on maximum working hours, and the need for efficiency improvements. Additionally, the transmission of skills due to an aging workforce has become a significant issue, with a high turnover rate among younger employees who are supposed to carry on these skills. In this seminar, we will discuss the causes of turnover based on case studies and explain key points on how to reduce turnover rates by advancing IT integration.

**Seminar Overview** "Generative AI," which is gaining attention as a method for improving business efficiency and utilizing internal digital transformation (DX), can be influenced by the literacy of the employees using it, potentially increasing the burden of work instead. In this seminar, we will discuss the current challenges of generative AI while providing examples of how it can be used to enhance business efficiency. We will also explain how to utilize generative AI in a way that achieves efficiency without being dependent on the user's skills. We hope this will serve as a reference for considering the use of generative AI.

**Seminar Overview** The reality that young members leave their jobs due to miscommunication with their superiors occurs in every industry. This is also true in the construction industry. The long-standing issues of labor shortages, regulations on working hours, and the challenges of passing on skills due to an aging workforce are significant problems. However, the misalignment in communication with young employees, who are supposed to be receiving this knowledge, may actually worsen the situation. In this seminar, we will discuss the causes of communication gaps as seen through case studies, and talk about methods for skill transfer, knowledge accumulation, and smooth internal communication using IT tools.
