I have added 'Understanding Bandpass Filters in 5 Minutes! A Thorough Explanation' to the technical trend keywords.

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.

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.

It is a filter designed to transmit light in two specific wavelength bands while blocking (preventing) other wavelength bands. It is ideal for surveillance cameras and similar applications.

1) Are you facing issues like this? ■ I want to pass visible light and part of the infrared wavelength (850nm), is that possible? ■ I definitely want to cut out the blocking range that causes noise. ■ Since there is a range of incident angles, can that be taken into account? ■ The shape is special, but can it be shipped as a part? 2) Dual-band pass filter (multi-band pass filter) This is a filter designed to transmit light in two specific wavelength bands while blocking (stopping) other wavelength bands. In addition to regular IR cut, it has the function to selectively transmit only specific near-infrared wavelengths (such as 850nm, 905nm, 940nm, 1064nm). For example, it is ideal for applications that require monitoring during both day and night by transmitting specific visible light and specific near-infrared light. With 40 years of experience, we have achieved sharp wavelength separation and high transmission rates. Our unique control technology during film formation allows for high durability and reduced shift.

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 future public works, not only construction quality but also safety measures, environmental considerations, labor-saving, and the use of new technologies will be important, along with the ingenuity applied on-site. In this context, the "Hyper CLT Board," a wooden lightweight mat using CLT, can be utilized. It can be used as a wooden mat for temporary roads, access routes, and heavy machinery work yards, and the 5×10 board weighs approximately 230 kg, making it relatively lightweight. In addition to ease of installation, removal, and relocation, it features the suppression of glare and metallic sounds unique to wood, as well as environmental considerations. Furthermore, it is a product that can easily incorporate proposals for the use of new technologies and creative ideas, as it is registered with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A." However, simply being registered with NETIS does not automatically result in additional points. What is important is to clarify the purpose and effects of its use on-site. Wooden mats, NETIS, civil engineering, CLT. The Hyper CLT Board is a new option to connect on-site ingenuity to evaluation.

Our company has launched the new "Kappa twin" dual-wheel caster for ultra-heavy load transport. It achieves a high load capacity of up to 2,200 kg per wheel, making it an optimal solution for transporting heavy items in industries such as automotive, aerospace, special vehicles, and heavy industry. The dual-wheel structure distributes the load, balancing high load capacity with excellent mobility. By reducing starting and rolling resistance, it supports smooth transport even for trolleys in the several-ton class. Additionally, it excels in turning performance, contributing to improved maneuverability in limited spaces. It is also suitable for AGVs (automated guided vehicles) and heavy transport trolleys, providing the stability, durability, and safety required in high-load environments. It covers weight ranges that were difficult to address with conventional products, contributing to solving transport challenges in manufacturing settings. This new product is recommended for companies looking to transport ultra-heavy items "more lightly and more safely."

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks 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 at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
