Co-creation proposal! Added 'Beauty Tech × Optical Thin Films' as a technology trend keyword.

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

We will achieve optical characteristics that have not been realized before by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high-refractive-index 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. A characteristic feature is that no optically unnecessary ripple occurs outside the stopband. We can achieve optical characteristics that were not possible with previous 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 Gohsui Seiko Glass).

Applications in the ultraviolet region are on the rise. At Itsuki Seiko Glass, we have developed filter glass substrates in the 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 region, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to transmit only specific wavelengths using aspheric lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Given the limited substrates and deposition materials, is anti-reflective coating feasible? ■ I've heard that measurement difficulty after film deposition is high; can you accommodate this? ■ Is it true that controlling the thickness in the UV region is very challenging due to its thinness? 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 aspheric lenses and lens arrays in combination with our deposition technology, we can propose new applications.

A bandpass filter that achieves sharp rise and high transmittance in the visible light range (660nm). It is ideal for red laser diodes and LED applications.

Are you having trouble with something like this? - Is it possible to only allow a specific wavelength (633nm) to pass through? - I would like to expand the stop band because light other than the desired wavelength becomes noise. - Can you take into account the range of incident angles? - The shape is special; can it be shipped as a component? Optical bandpass filters are used in various optical applications and are essential for selectively extracting light of specific wavelengths. Passband: An optical bandpass filter allows a specific range of wavelengths to pass through. This range of wavelengths is called the passband and is typically defined by the center wavelength and the wavelength bandwidth. Wavelength selectivity: Optical bandpass filters can have very high wavelength selectivity, emphasizing light of specific wavelengths. This is important in many fields where precise wavelength selectivity is required. A 660nm bandpass filter, which selectively allows light in the specific wavelength range of 660nm to pass through, is commonly used in optical applications. This bandpass filter amplifies or allows light within the wavelength range around 660nm while blocking light of other wavelengths.

It is possible to efficiently transmit light while removing wavelengths that contribute to heat from the light source. It is ideal for medical lighting devices (such as dental mirrors).

【1】Are you facing any of these issues? ◆ I want to prevent the temperature from rising due to near-infrared light emitted from the light source. ◆ The device itself is getting hot, and I want to do something about it. ◆ Is it possible to reflect visible light while allowing near-infrared (NIR) to pass through? ◆ Can the wavelength range of the mirror be customized? 【2】What is a cold mirror? A cold mirror is a filter that transmits near-infrared light while reflecting visible light. By forming a dielectric multilayer film, it can efficiently transmit thermal radiation without absorption, removing wavelengths that contribute to heat contained in the light source. Additionally, due to the excellent heat resistance and weather resistance of the dielectric multilayer film, it plays a role in stabilizing products that incorporate the filter. Typical applications include liquid crystal projectors, medical lighting fixtures, and dental mirrors that you may have seen on dental chairs. It has the performance of a mirror while featuring a special coating that allows near-infrared wavelengths to pass through to prevent temperature rise in the irradiated area.

【1】Are you facing any of these issues? ◆Is it possible to prevent reflection by matching the wavelength of CDs and DVDs? ◆Is there a way to improve visibility and achieve clear image quality? ◆Can we design and deposit custom solutions? ◆I want to increase light output to contribute to energy savings. ◆Can we design an anti-reflective coating (AR) that considers the angle of incidence? 【2】Features of Adachi New Industry's dual-wavelength AR (anti-reflective coating) 1) It is compatible with two wavelengths for CD (780nm) and DVD (650nm). We also offer custom designs that accommodate both DVD (650nm) and Blu-ray/HD-DVD (405nm). 2) It prevents light reflection from both sides of the substrate (thereby improving transmittance). Because it minimizes light loss, clear images can be obtained even in complex optical systems with long optical paths without degrading the incident light. 3) It can accommodate a variety of substrates, including glass and resin films. However, since our process is batch (sheet-type), the maximum size is □200mm.

This is a bandpass filter that achieves a sharp rise and high transmittance in the infrared range (905nm). It is ideal for TOF sensors and LiDAR.

Are you facing any of these issues? - Is it possible to only transmit specific wavelengths in the infrared range? - I would like a bandpass filter suitable for TOF sensors. - I heard that the wavelength used in LiDAR is 905nm; can you create a film for that? - Since light other than the desired wavelength will cause noise, I would like to widen the stop band. - Given the range of incident angles, can this be taken into account? - Is it possible to mount this on AGVs or OHTs? The 905nm bandpass filter is a filter that transmits specific wavelengths by utilizing light interference through the deposition of dielectric films. Based on our proven results in visible light, we can achieve sharp wavelength separation and high transmission rates in the infrared range (905nm) by controlling the deposition process, making it ideal for photoelectric sensors (such as TOF sensors) that require delicate light.

Standard stock items include anti-reflective films, bandpass filters (BPF filters), and infrared cut filters (IR cut filters), among others.

We will start selling some optical thin film products (optical filter products) and patterned processing products as "standard stock items." We have responded to such requests! ◆ It's difficult to bear the cost of a whole batch when only a few pieces are needed for experiments... ◆ I want to see product development and performance tests quickly, so I need a few pieces at different levels... ◆ I just want to try it out for now... We often hear such voices through inquiries from our website. Even if custom-made filters are ultimately needed, I believe it is very difficult to define complete filter performance from the beginning.

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
