(Headquarters: Hachioji City, Tokyo), Representative Director Koji Nagata will resign in July 2024, and Factory Manager Hirokazu Nakanishi will be appointed as the new Representative Director. We will continue to work together as a united team, and we appreciate your continued patronage. Sincerely,

[Hachioji City] 2023 Fiscal Year 3rd Advanced Technology Seminar (Theme: Expanding Applications of LED - Latest Ultraviolet LED) Our company will participate as a speaking company. We will present on the topic "Transition from Existing Lamps to LED from the Perspective of a Light Source Provider." We hope you can join us. Date: February 19, 2024 (Monday) 14:00 - 16:20 Location: Tokyo Tama Future Messe, Conference Room 4 Overview In recent years, due to the growing interest in energy conservation, LED lighting has increasingly replaced traditional bulbs and fluorescent lights. With the broadening wavelength range and higher output of LEDs, their applications have expanded to include traffic lights and car headlights, and they also contribute to miniaturization, lightweight design, and greater design flexibility. Additionally, compared to traditional light sources, LEDs have a longer lifespan and require less frequent replacement, significantly enhancing maintenance efficiency. Recently, the commercialization of ultraviolet LEDs has also progressed, opening up new possibilities. At this seminar, there will be a keynote speech by Professor Onuma from Kogakuin University covering the basics and history of LEDs, as well as cutting-edge LED research. Furthermore, local companies Taiyo Kogyo Co., Ltd. and Tsubosaka Electric Co., Ltd. will introduce specific examples using ultraviolet LEDs. We look forward to your participation.

We are pleased to announce that we will be exhibiting at the "NEPCON Japan 15th International Automotive Electronics Technology Exhibition" in order to widely inform everyone about our products. Our booth will feature a variety of products, including near-infrared and high-color-rendering LED light sources, as well as many new products. We apologize for the inconvenience during your busy schedule, but we would like to invite you to take a look at our products and technologies. For more details, please refer to the attached PDF. Date: January 25 (Wed) - January 27 (Fri), 2023, 10:00 AM - 5:00 PM Location: Tokyo Big Sight Booth Number: East Exhibition Hall 46-8

We will start selling an exposure device equipped with a 2kW ultra-high pressure mercury lamp, ensuring parallelism. It is intended for photolithography processes.

We have started selling a spectral reproduction light source using four types of white LEDs with different color temperatures and 26 types of monochromatic LEDs. It is equipped with spectral properties, allowing for the measurement of current brightness, color, and spectrum, and it is also capable of reproducing spectra from data created in CSV format.

A major chart manufacturer has discontinued the production of transparent color charts. Therefore, we have prepared charts for our customers who are using our light sources. We will set a standard model, but custom options are also available. We have introduced the charts on YouTube. Please contact us for more details.

The "Automotive Technology Exhibition" will be held this week. We will be showcasing simulated sunlight lighting at the Wycoff Science Corporation booth. Date: May 25 (Wednesday) to 27 (Friday), 2022 Location: Pacifico Yokohama Event website: https://aee.expo-info.jsae.or.jp/ja/ Booth number: 262 At the booth of Fujikagaku System Co., Ltd. (including Wycoff Science Corporation) There will be a video display on a monitor. This video was created specifically for this exhibition. The main focus is on the introduction of the "simulated sunlight lighting" product and its applications. We will also have the actual SOL-100-01D06 on site, so if you would like to see it, please ask the staff on site.

This is a YouTube channel that mainly introduces how to operate products and their specifications, but we have started a project to convey information in a more casual manner. The first installment is "Measuring the Performance of Action Cameras." And the first episode is "About Flicker." Please be sure to check out our YouTube channel.

We would like to inform you that we will be revising the product prices and packaging shipping fees for many models. We have been making efforts to maintain our selling prices, but due to the global semiconductor shortage and the nylon shortage, it has become extremely difficult to absorb the rising raw material costs, which in some cases have exceeded 1000%, and maintain our prices. Our products include not only standard items listed on our website but also many customized products tailored for each customer, so the revised prices will vary by product. For more details, please refer to the PDF.

A baffle has been added as a part compatible with the SIS series of white silicone integrating spheres. When multiple openings are present, other openings can be directly viewed as they are, but by installing this baffle, a partition is created. The baffle is compatible with an opening of φ52.

We have released a video explaining the auto-calibration function that connects our luminance meter to the luminance box. This function adjusts the values of the light sensor inside the luminance box (the reference value for reproducing luminance) to match the LC-5. 1) Simplified calibration when you have multiple luminance boxes. 2) Simplified calibration of the luminance box on a regular basis. 3) When aligning with the values of the luminance meter you own. The luminance box compatible with auto-calibration is equipped with an "LC" connector. A dedicated cable is used to connect the luminance box and the luminance meter.

The VLB-10 series, with a thickness of approximately 6 cm, is compact yet capable of "highly uniform surface emission" and "accurately outputting brightness." We have received repeat orders based on feedback such as "it's easy to use, so other departments want it too." We have created an explanatory video to demonstrate the operability of this device.

We have created a lighting box with high color rendering and broad spectrum that simulates sunlight. This is the first demo unit.

We have various optical data for the surface light source LSB-1010FBW-CRI. 1: Spectral radiance data 2: Spectral irradiance, irradiance, and PPFD data Due to the data size, please request it through the inquiry form if you are interested.
