"Thorough explanation of jigs for optical thin film deposition!" has been added to the technical trend keywords.

We offer contract processing for analytical chips for electrochemical (bio) measurements.

Are you facing any of these issues? - It's difficult to manage delivery times when ordering thin film processing and pattern processing separately. - I haven't put it into a drawing, but can you provide consultation? - I want to achieve fine wiring, but I would like advice on film materials. - Can you accept just pattern processing? - Can you handle line and space (L/S) down to 10μm? 1) We realize fine pattern processing. We achieve fine patterning through photolithography, etching, and metal masks. We select the best processing method and resist according to the customer's requirements. 2) We can provide integrated production from substrate procurement to film formation. At Adachi New Industry, we can respond to custom orders consistently from substrate procurement to film processing, fine processing, and chip processing. It is also possible to cut into any shape and ship as components. However, we need detailed drawings, etc. 3) We accommodate cleanroom requirements. The working environment maintains the necessary cleanliness for each stage from film formation to inspection, and we have a thorough system in place to address minor film defects (such as foreign substances in the film).

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?

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

Applications in the ultraviolet region are on the rise. At Itsuki Seiko Glass, we have developed filter glass substrates in the 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 region, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to transmit only specific wavelengths using aspheric lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Given the limited substrates and deposition materials, is anti-reflective coating feasible? ■ I've heard that measurement difficulty after film deposition is high; can you accommodate this? ■ Is it true that controlling the thickness in the UV region is very challenging due to its thinness? 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 aspheric 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.

The short pass filter selectively transmits light with wavelengths below a specific wavelength (800nm) while blocking light with longer wavelengths. This allows for effective handling of light in specific wavelength bands. (Do you have any of the following concerns?) ■ Is it possible to customize due to high wavelength dependence? ■ If light is incident at an angle, performance decreases; can it be controlled? ■ When blocking specific wavelengths, there may be a decrease in transmittance. ■ 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 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.

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.
