Craftsman's Point: Achieving optical properties with a periodically varying refractive index. Applications: Expected applications in notable fields such as Raman spectroscopy.

We will achieve optical characteristics that have not been realized until now by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high refractive index films and low refractive index films, which exhibit specific optical properties. In contrast, notch filters (band-stop filters) are deposition products designed to periodically change the refractive index in the thickness direction. They are characterized by the absence of optical ripples outside the stopband. We can realize optical characteristics that have not been achievable with conventional optical thin film processing. (Do you have such challenges?) ■ Is it possible to reflect only around the wavelength of 532nm? ■ I would like the unnecessary parts to be unable to transmit optically. ■ Notch filter? Band-stop filter? Rugate filter? ■ I have heard that the measurement difficulty after deposition is high; can you accommodate this?

It is an optical filter that selectively transmits ultraviolet wavelengths (255 nm) while blocking light of other wavelengths (using a substrate from Hisashi Seiko Glass).

Applications in the ultraviolet region are on the rise. At Isuzu Seiko Glass Co., we have developed filter glass substrates (IHU series) that have a transmission limit wavelength in the ultraviolet range and improved weather resistance to ultraviolet light. Recently, we have successfully deposited dielectric multilayer films to create bandpass filters in the ultraviolet range, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to selectively transmit specific wavelengths using aspherical lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Is it possible to achieve anti-reflection with limited substrates and deposition materials? ■ I've heard that measurement difficulty after deposition is high; can you handle that? ■ Is it true that controlling the thickness in the UV region is very difficult due to its thin film? Based on our achievements in visible light, we can achieve high transmission rates in the ultraviolet wavelength range by controlling the deposition process. Additionally, by leveraging our ability to mold aspherical lenses and lens arrays in combination with our deposition technology, we can propose new applications.

It is an optical filter that selectively transmits light below a specific wavelength and blocks light of longer wavelengths.

A short-pass filter selectively transmits light below a specific wavelength (800nm) and blocks light of longer wavelengths. This allows for effective handling of light in a specific wavelength range. (Do you have any of the following concerns?) ■ Is it possible to customize due to high wavelength dependence? ■ Does performance decrease when light is incident at an angle, and can it be controlled? ■ There may be a decrease in transmittance when blocking specific wavelengths. ■ Can it cause chromatic aberration? ■ Is it difficult to control multiple wavelengths simultaneously?

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.

We have introduced the commercial aroma diffuser "Majesta Fragrance" to a cabaret club in Tokyo. The selected scent is "Royale," which offers a sense of calm and elegance. It spreads naturally throughout the floor, creating a high-quality space that satisfies the five senses. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in enhancing your store's scent experience, please feel free to contact us.

We have released a catalog for a trial version of a conceptual skills course designed to efficiently develop logical thinking and problem-solving skills in a short period. The course is structured in three levels, from basic to practical and applied, supporting skill enhancement directly related to work through video viewing, exercises, and detailed feedback. There is also a free trial version available, lasting about 10 to 20 minutes, allowing you to easily check the course content and approach. It is ideal for promotion and advancement exam preparation, as well as for developing the next generation of leaders, with a proven track record in many companies. For detailed materials or to apply for the trial version, please use the link below. Feel free to take advantage of it!
