The keyword "cutting methods for optical thin films" has been added to the technology trend keywords.

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

We will achieve optical characteristics that have not been realized until now by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high refractive index films 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. They are characterized by the absence of optical ripples outside the stopband. We can realize optical characteristics that have not been achievable with conventional 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?

It is an optical filter that selectively transmits ultraviolet wavelengths (255 nm) while blocking light of other wavelengths (using a substrate from Hisashi Seiko Glass).

Applications in the ultraviolet region are on the rise. At Isuzu Seiko Glass Co., we have developed filter glass substrates (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 range, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to selectively transmit specific wavelengths using aspherical lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Is it possible to achieve anti-reflection with limited substrates and deposition materials? ■ I've heard that measurement difficulty after deposition is high; can you handle that? ■ Is it true that controlling the thickness in the UV region is very difficult due to its thin film? 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 aspherical lenses and lens arrays in combination with our deposition technology, we can propose new applications.

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

A short-pass filter selectively transmits light below a specific wavelength (800nm) and blocks 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 possible to customize due to high wavelength dependence? ■ Does performance decrease when light is incident at an angle, and can it be controlled? ■ There may be a decrease in transmittance when blocking specific wavelengths. ■ Can it cause chromatic aberration? ■ Is it difficult to control multiple wavelengths simultaneously?

It is a mirror that reflects light of a specific wavelength and transmits light of other wavelengths.

【1】Are you facing any of these issues? ◆ Is it possible to maintain a uniform reflectance for multiple wavelengths? ◆ Is it possible to address the decrease in reflectance 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 the parts even if the shape is special? 【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, permitting only the desired wavelengths of light to pass through.

We offer mirrors that combine reflective performance and cost-effectiveness. By depositing a dielectric multilayer film on the surface, we achieve excellent durability.

Are you facing any of these issues? ■ I want a mirror with a higher reflectivity than a standard aluminum mirror. ■ I want a durable mirror, but can it be designed with a dielectric? ■ Can you take into account the wide range of incident angles? ■ The shape is special, but can it be shipped as a part? The aluminum enhanced reflective mirrors manufactured by Adachi Shinsan Industry Co., Ltd. can achieve excellent performance with minimal light loss during reflection and outstanding environmental durability by layering and controlling dielectrics. They can be customized to fit specific optical designs and are intended to have reflective properties suitable for specific wavelength ranges and 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 want to block other wavelengths of light as they become noise, so I would like to widen the stop band. - Since there is a range of incident angles, can this be taken into account? - The shape is special, but 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.

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 rays without absorption, removing the 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 LCD projectors and medical lighting equipment, particularly dental mirrors that you may have seen on dental treatment 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.
