We have added the 'Short Pass Filter 800nm' to our standard inventory.

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 an optical filter that cuts ultraviolet and infrared light while having a high transmittance in the visible light range.

A UV-IR cut filter is a filter that cuts light in the ultraviolet and infrared regions while having a high transmission rate in the visible light region. In other words, it is an optical filter that simultaneously realizes the properties of both a UV cut filter and an IR cut filter. By placing it in front of CMOS sensors or CCD sensors, it serves multiple roles, such as cutting out noise-inducing light, providing heat protection for various light sources, and preventing degradation of LCD components due to ultraviolet light. It is an excellent optical filter and optical thin film with multiple functions. Are you facing any of these issues? - Is it possible to cut both ultraviolet and near-infrared light? - Can a filter be made that allows visible light to pass while blocking IR and UV wavelengths? - I want to reduce noise light and increase the sensitivity of the sensor. Can I consult with you? - Is it possible to custom adjust the wavelength range that I want to transmit? - Is processing to chip size possible?

It is a dielectric multilayer film filter that transmits visible light and reflects near-infrared light.

It is used as a near-infrared cut filter that adversely affects CCD devices such as video cameras. The optical characteristics, such as the wavelength position with a transmittance of 50%, transmittance, and cut wavelength band, can be set arbitrarily. (Do you have such challenges?) Is it possible to cut only the wavelength of near-infrared light? I want to allow visible light to pass while blocking the wavelengths of IR. I want to suppress light that causes noise and increase the sensitivity of the sensor. Can the wavelength range I want to transmit be custom adjusted? Is it possible to process it to chip size?

Kort Valuta Inc. (Head Office: Shibuya, Tokyo; CEO: Hideki Shibata) is pleased to announce that we will hold our next recruitment event, “Kort Valuta Night,” on November 26, 2025. This recurring event offers an opportunity for potential candidates to casually learn about our company culture and team atmosphere before applying. By lowering the barrier to entry and providing authentic insights from current employees, the event helps participants gain a more concrete sense of what it’s like to work at Kort Valuta. Since the event’s launch, approximately ten attendees have gone on to join the company in a range of roles — including marketing, customer support, and backend engineering.

The recognition that "the PDF invoice received from the other party must be stored as electronic data" is widely accepted. However, is that response truly sufficient for perfection? ◆ The "receipt" of electronic transactions includes issuance and delivery The Electronic Bookkeeping Act defines "electronic transactions" as the receipt of electromagnetic records related to transaction information. Breaking down the term "receipt" is key to understanding. - "Receipt": Receiving electronic data such as invoices and receipts from business partners - "Issuance": Issuing and delivering electronic data such as invoices and estimates to business partners When downloading a PDF from your company's accounting system and attaching it to an email, or concluding electronic contracts through a cloud-based invoicing service, both the receiving party and the issuing party (your company) are obligated to store the data. 【Utilizing paperlogic DESKTOP for document management】 - Elimination of manual input - Assurance of reliable searchability - Centralized management of receipt and issuance → paperlogic DESKTOP addresses the challenges of complex metadata management in the storage of these issued documents.

We are pleased to announce that Arsystem Co., Ltd. has received the "Health Management Excellent Corporation 2025" and "Next Bright 1000*" certifications under the Health Management Excellent Corporation Certification System promoted by the Ministry of Economy, Trade and Industry and the Japan Health Conference. *Certified corporations that applied for Bright 500, ranking from 501 to 1500. This year, we are also able to receive the new certification "Next Bright 1000," and we feel happy to have taken another step toward realizing our vision of being "the company that values its employees the most on Earth." Moving forward, we will continue to strive to create a "Love Al" environment where each of our valued employees can work healthily and energetically, both physically and mentally.
