【1】Are you facing any of these issues? ◆ Is it possible to maintain a uniform reflectance for multiple wavelengths? ◆ Is it manageable if the reflectance decreases at specific wavelengths? ◆ Is color reproducibility achievable? ◆ Is there no problem with the stability of optical performance due to temperature changes or variations in environmental conditions? ◆ Is it possible to ship parts with a special shape? 【2】What is a dichroic mirror? A dichroic mirror is a mirror that reflects light of specific wavelengths while allowing other wavelengths to pass through. It consists of multiple layers, each with different optical properties. This characteristic allows for the effective separation, combination, or blocking of light at different wavelengths. 【3】Features of dichroic mirrors - Spectral separation Dichroic mirrors are used for spectral separation by selecting and reflecting or transmitting light of specific wavelengths from incident light. For example, they are used in optical devices that extract and detect light of specific wavelengths. - Light filtering They are used as filters to selectively remove light of specific wavelengths. This allows for the removal of unwanted light, enabling only the desired wavelengths to pass through.

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?

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.

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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out 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. ◎ If a detailed technical explanation is needed, please contact us.
