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. We have standard stock items available, so please consider them. https://www.e-coating.jp/stock/cat/filmtype/bandpassfilter/

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 civil engineering sites, plywood is used for temporary roads, access roads, heavy machinery work yards, and material storage areas. Steel plates are common materials, but they tend to produce metallic sounds during vehicle passage and installation/removal, which can be a noise issue in construction near residential areas, schools, and hospitals. Hyper CLT plywood is a civil engineering CLT material that utilizes wood CLT. As wooden plywood, it can be used for mud prevention, ground protection, and ensuring work pathways, and its natural and soft texture helps create a different site environment compared to metal plates. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which reduces the burden of transportation, installation, and removal. Additionally, it is easy to use for proposals that consider glare reduction and environmental considerations, making it recommended for innovative public works. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," we can propose it to companies considering noise measures, wood, plywood, timber, civil engineering, and civil engineering CLT. It is also suitable for construction that emphasizes consideration for the surrounding area and for sites considering alternatives to steel plates. We also accept requests for materials and consultations on implementation. Please consider wooden plywood as an option for temporary plans that take into account urban construction and neighboring measures.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those that face sidewalks or roadways are particularly prone to dangerous incidents, such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the departure warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be installed as an add-on, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
