I participated in the 52nd Optical Thin Film Research Conference.

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.

ND stands for "Neutral Density," which is a filter used to adjust the light transmission rate.

【1】Are you facing any of these issues? ◆ I want to address concerns about flares and ghosts. ◆ Is it possible to adjust the transmittance with a custom setting? ◆ I am looking for a filter for adjusting laser equipment. ◆ The shape is special; can it be shipped as a part? 【2】What is an ND filter? ND stands for "Neutral Density," which is a filter used to adjust the transmittance of light. It is attached to the lens to reduce the amount of light entering from outside. It is an essential optical component for controlling shutter speed and aperture in bright environments when taking photographs with cameras, in order to achieve the appropriate exposure. 【3】Design and customization available for your desired wavelength range At Adachi New Industries, we can design and coat (film) according to your desired wavelength range. The characteristic chart at the beginning shows a transmittance of 50%, but we can accommodate other transmittance levels as well. Please feel free to contact us. Additionally, we will design according to the characteristics of the substrate and your requirements, so please let us know your desired substrate type and wavelength range when you inquire.

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 on 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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

In the field of collaborative robots, there is a demand for reduced startup labor, energy efficiency, and safe yet flexible handling performance. In particular, reliance on compressed air systems and complex wiring and piping can pose challenges during installation and operation. Piab's "piCOBOT Electric for ABB GoFa" is a plug-and-play electric vacuum gripper solution optimized specifically for ABB GoFa. Its all-electric design generates vacuum using only electricity, eliminating the need for compressed air. This enables the creation of a clean, quiet, and energy-efficient collaborative robot cell. Furthermore, by adopting ABB GoFa-specific software plugins, designated cables, and standard ISO machine interfaces, smooth integration into the ABB control environment is possible. This supports rapid startup and stable operation. Read the article here: https://www.piab.com/ja-jp/news/piab-launches-picobot-electric-for-abb-gofa

We have added the DL material "Explained in Manga! Let's Prevent Technical Information Leakage to the Outside with CrackProof Software Protection!" to the DNP Hypertech site. In the manufacturing industry, there is a growing awareness of measures against the leakage of technical information. Many companies seem to have already established sufficient rules and measures for information protection when exchanging data with external parties. However, when it comes to cases where in-house software suffers from cracking (unauthorized analysis and tampering) and information leaks occur, the current measures are still not adequate. We have explained the measures against technical information leakage through software protection in an easy-to-understand manga format. Please take a look.
