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 transmits light of a specific wavelength while reflecting light of other wavelengths. It transmits visible light of a specific wavelength and reflects its complementary color.

【1】Are you facing any of these issues? ◆Can you transmit light of specific wavelengths while reflecting others? ◆Can you create a filter to control RGB (red, green, blue) colors? ◆What are effective filters for fluorescent imaging? ◆Is customization possible for focusing on specific wavelength bands or removing unwanted wavelengths? ◆Is it possible to ship parts with special shapes? 【2】What is a dichroic filter? A dichroic filter is an optical filter that transmits light of specific wavelengths while reflecting light of other wavelengths. It allows visible light of a specific wavelength to pass through and reflects its complementary color, enabling color separation and color synthesis. Due to the absence of light loss from absorption or scattering, it allows for high-efficiency color separation and synthesis, and is used in many optical devices such as cameras, spectrometers, laser applications, and optical microscopes. 【3】Features ・Wavelength selectivity: Transmits light of specific wavelength bands while reflecting other wavelengths ・Use in optical devices: Used in optical devices such as cameras, spectrometers, and microscopes ・Fluorescent imaging: Utilized in biology and medicine for fluorescent imaging, allowing simultaneous detection of fluorescent substances at different wavelengths.

This is an infrared wavelength filter optimized for optics, with plasma control technology enhanced to its limits.

Infrared materials are incredibly fragile! (Weak against scratches, water, and chemicals) This common understanding can be overturned with our company's technology. 1) Excellent infrared transmission characteristics This is a filter that transmits infrared light through the formation of a multilayer film and its interference effect. It achieves excellent transmission rates from the near-infrared to far-infrared regions. 2) Custom design and customization for desired wavelength ranges We can design and deposit films tailored to the wavelength range requested by our customers. Please inform us of the substrate type and wavelength range when making inquiries, as we will design according to the characteristics of the substrate. 3) Measurement equipment: We own FT-IR Rest assured that we will always attach a measurement chart (spectral characteristics) upon shipment. 4) Component support is also possible We can not only procure substrates and deposit films but also cut them into any shape and ship them as components. However, we will need detailed drawings. 5) Cleanroom compliance Our working environment maintains the necessary cleanliness levels from film deposition to inspection, and we have a robust system in place to address minor film defects (such as foreign particles in the film).
