"Thorough explanation on how to choose optical bandpass filters!" has been added to the technical trend keywords.

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/

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.

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.

There are no changes to the phone numbers or inquiry email. Phone numbers: 03-5944-9199, 03-5944-9198 Inquiry email: sales.jp@keller-pressure.com We appreciate your continued support.

Happy New Year! Thank you very much for your exceptional support over the past year. Yoshikawa Co., Ltd.'s Realization Division will continue to contribute to solving your challenges this year as a "Realization House" that transforms your thoughts of "I want to do this" and "Is it possible to do something like this?" into reality, utilizing our skilled stainless steel processing technology. We are pleased to announce that we will be exhibiting for the first time at "The 40th NEPCON Japan," which will be held at Tokyo Big Sight from **January 21 (Wednesday) to 23 (Friday), 2026**, to introduce our technologies and products in greater depth. At our booth, we will showcase a variety of slide-type metal mask dedicated shelves that contribute to improving productivity in the electronics field. These not only lead to efficient management and improved workability in limited spaces but can also be customized according to your needs. We invite you to visit our booth at Tokyo Big Sight during this opportunity. We welcome inquiries such as "Can this processing be done?" and look forward to seeing you there.

Happy New Year. We look forward to your continued support this year as well. Last year, there were notable winter natural disasters such as earthquakes in Hokkaido, Tohoku, and the northern Kanto region. We sincerely express our condolences to those affected and pray for the safety of those working on recovery efforts, as well as for the new year to be bright and peaceful. In 2026, we will work together as a company to create a "more user-friendly website that can be viewed every day," and we will strive for challenges and improvements in "energy-saving and environmentally friendly equipment and maintenance." We appreciate your continued support this year as well. Toyota Kikan Co., Ltd.
