"Co-creation proposal! Entertainment/Exhibition × Optical Thin Films" has been added as a technology trend keyword.

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.

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 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.

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 would like to expand the stop band because light other than the desired wavelength becomes noise. - Can you take into account the range of incident angles? - The shape is special; 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.

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 to 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 you require a detailed technical explanation, please contact us.

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances.
