In this document, we introduce an example of measuring transmittance using the high-precision spectrometer "Neo" to investigate the attenuation level. We also provide detailed information about "ND filters," which are used to reduce the amount of light entering from the lens, and about "transmittance," which refers to the ratio of incident light that passes through a target substance using specific wavelengths of incident light. The content is presented with images and diagrams, making it a user-friendly reference. We encourage you to read it and make use of it.

We would like to introduce a case study in collaboration with Cutting Edge Coatings GmbH (CEC) regarding the introduction of the Neo series spectroradiometer for the development of ion beam sputtering (IBS) deposition systems. During the coating process, the absolute transmittance of the generated layers, meaning the filters being manufactured, constantly changes with each layer produced. Therefore, it is crucial to obtain reliable and predictably linear responses from the spectrometer, even if the transmittance values are low. To address this challenge, the adoption of the new Neo spectroradiometer platform has enabled the produced filters to meet stricter tolerances. [Case Overview] ■ Challenges - The filters being manufactured constantly change with each layer produced. - It is important to obtain reliable and predictably linear responses from the spectrometer. ■ Results: The produced filters can now accommodate stricter tolerances. *For more details, please refer to the PDF document or feel free to contact us.

In this document, we introduce Admesy's new calibration concept aimed at improving the accuracy of spectroradiometers. The accuracy of a spectroradiometer depends on various factors such as optical design and manufacturing tolerances, and the calibration of the spectrometer itself is a crucial element for achieving precise spectral measurements. We provide a detailed explanation of the four steps involved in the calibration of spectroradiometers, including the characteristics and limitations of traditional calibration lamps, as well as Admesy's improved approach compared to conventional methods. We encourage you to read it. [Contents] ■ Calibration of spectroradiometers is performed in the following four steps ■ Characteristics and limitations of traditional calibration lamps ■ Admesy’s Crius halogen calibration light source: improved features and performance ■ Breakthroughs in calibration: Admesy’s improved approach compared to traditional methods ■ Dedicated access to the Crius halogen calibration light source *For more details, please refer to the PDF document or feel free to contact us.

As you may know, soy sauce has a dark brown color. This is due to the browning that occurs during the manufacturing process. When it is in a container of the same color, it cannot be distinguished by visual inspection or the peak wavelength of transmitted light alone. Therefore, by using ultraviolet and blue light sources to measure transmitted light, we confirmed that a slight fluorescence could be observed. By confirming the fluorescence reaction, it is possible to detect the presence of soy sauce even in colored containers. The fluorescence reaction is a phenomenon that occurs when specific wavelengths are absorbed. These wavelengths vary depending on the substance. Additionally, not all substances exhibit fluorescence reactions; this phenomenon is observed in a limited number of substances. [Summary] ■ Light source: Peak wavelength 449nm / Wavelength range 400–500nm LED (Crius) ■ Sample: Water = 20ml + Soy sauce = 0.5ml (25%) ■ 1cm square plastic cuvette, using Neo dedicated cuvette holder *For more details, please refer to the PDF document or feel free to contact us.

This time, we will measure drinking yogurt products. The components of yogurt vary by manufacturer and product, so it is not guaranteed that the same results will be obtained for all types of yogurt. When blue light (peak wavelength 449nm) is applied to this drinking yogurt, the wavelength spectrum of the fluorescent response can be observed in the early part of the 500-600nm range on the right side of the transmitted light spectrum (400-500nm). There are many types of proteins, each reacting to different wavelengths. Generally, a wavelength light source of 280nm is used for testing protein content, but there are substances that can be detected at other wavelengths as well.
