UV-IR cut filter: Cuts ultraviolet and infrared rays, transmits visible light.

UV-IR cut filter: Cuts ultraviolet and infrared rays, transmits visible light.

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?

Multi-band pass filter (dual band pass filter)

Multi-band pass filter (dual band pass filter)

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.

905nm bandpass filter (near-infrared region): for TOF and LiDAR

905nm bandpass filter (near-infrared region): for TOF and LiDAR

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/

Information on standard stock items (optical filters)

Information on standard stock items (optical filters)

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.

Cold mirror: A filter that transmits near-infrared light and reflects visible light.

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.

Notch filter (band-stop filter, rugate filter)

Notch filter (band-stop filter, rugate filter)

Craftsman's Point: Achieved optical properties with a periodically varying refractive index. Application: Expected applications in notable fields such as Raman spectroscopy.

We will achieve optical characteristics that have not been realized before by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high-refractive-index and low-refractive-index films, which exhibit specific optical properties. In contrast, notch filters (band-stop filters) are deposition products designed to periodically change the refractive index in the thickness direction. A characteristic feature is that no optically unnecessary ripple occurs outside the stopband. We can achieve optical characteristics that were not possible with previous optical thin film processing. (Do you have such challenges?) ■ Is it possible to reflect only around the wavelength of 532nm? ■ I would like the unnecessary parts to be unable to transmit optically. ■ Notch filter? Band-stop filter? Rugate filter? ■ I have heard that the measurement difficulty after deposition is high; can you accommodate this?
