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

The short pass filter selectively transmits light below a specific wavelength while blocking 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 customizable due to its high wavelength dependence? ■ If light is incident at an angle, will performance decrease, and can it be controlled? ■ When blocking a specific wavelength, there may be a decrease in transmittance. ■ Can it cause chromatic aberration? ■ Is it difficult to control multiple wavelengths simultaneously?

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 an optical filter that cuts ultraviolet and infrared light while having a high transmittance in the visible light range.

A UV-IR cut filter is a filter that cuts light in the ultraviolet and infrared regions while having a high transmission rate in the visible light region. In other words, it is an optical filter that simultaneously realizes the characteristics of both a UV cut filter and an IR cut filter. By placing it in front of CMOS sensors or CCD sensors, it serves multiple roles such as cutting noise light, providing heat protection against various light sources, and preventing degradation of liquid crystal components due to ultraviolet light. It is an excellent optical filter and optical thin film with multiple functions. Are you facing any of these issues? - Is it possible to cut both ultraviolet and near-infrared light? - Can a filter be made that allows visible light to pass while blocking IR and UV wavelengths? - I want to reduce noise light and increase sensor sensitivity. Can I consult about this? - Is it possible to customize the wavelength range that I want to transmit? - Is processing to chip size possible?

It is a filter that efficiently cuts (reflects) short-wavelength UV (ultraviolet) light while allowing visible light to pass through.

What is a UV cut filter (ultraviolet cut filter)? It is a filter that cuts ultraviolet (UV) light while allowing visible light to pass through. In digital cameras, it is used to reduce chromatic aberration, and in liquid crystal projectors, it is used to prevent the degradation of liquid crystals and other optical components caused by the light from lamps (such as high-pressure mercury lamps), with the aim of cutting unnecessary ultraviolet light. Are you facing any of these issues? ◆ Is it possible to cut only the wavelength of ultraviolet light? ◆ Can a UV cut filter for projectors be coated? ◆ I would like to consult about the degradation of optical components. ◆ I would like to consult about filters that minimize the impact on the human body. ◆ Is it possible to custom adjust the wavelength range that I want to transmit?

It is a dielectric multilayer film filter that transmits visible light and reflects near-infrared light.

It is used as a near-infrared cut filter that adversely affects CCD devices such as video cameras. The optical characteristics, such as the wavelength position with a transmittance of 50%, transmittance, and cut wavelength band, can be set arbitrarily. (Are you facing such challenges?) Is it possible to cut only the wavelength of near-infrared light? I want to allow visible light to pass while blocking IR wavelengths. I want to suppress light that causes noise and increase the sensitivity of the sensor. Can the wavelength range I want to transmit be custom adjusted? Is it possible to process it to chip size?

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.
