Section preparation using a microtome! Introducing examples of observing lens coating layers and multilayer films.

Lenses for glasses, cameras, and other devices are coated with various layers. In the case of glasses, multiple coating layers are applied, including a hard coat to protect plastic lenses, an anti-reflective coat to reduce light reflection, and a UV coat to block ultraviolet rays. These layers are applied as extremely thin films, so we observed their structure in cross-section. When observed with a scanning electron microscope (SEM), it was noted that a hard coat/multilayer film is applied on top of the lens substrate, and in the multilayer film, SiO and Nb films are alternately stacked. [Overview] ■ Cross-section preparation method - Prepared with a microtome - The lens removed from the frame was cut into small pieces and embedded in resin - Subsequently, a cross-section was prepared using a microtome, followed by optical microscopy observation, SEM observation, and EDX analysis. *For more details, please refer to the PDF document or feel free to contact us.

Digitizing transparency and color into numerical data! Objectively evaluating transparency rate and yellowing degree!

This introduction covers the evaluation of transmittance and yellowing (yellowness) using a color difference meter. By making the product's constituent materials transparent and richly colored, necessary functional characteristics, artistic qualities, and design elements for the product's application are imparted. However, yellowing (discoloration) can occur due to the environment in which they are used, potentially compromising those characteristics. By quantifying transparency and color not through human perception but as numerical data, objective evaluation becomes possible. 【Overview】 ■ Principles of color difference measurement and acquired data (XYZ Yxy color space) - Light emitted from a light source passes through a transparent sample, and within an integrating sphere box, data on the transmitted wavelengths (transmittance) and converted color space data are obtained. *For more details, please refer to the PDF document or feel free to contact us.

Measure the Raman spectrum! It is possible to obtain information about the structure and crystallinity of carbon materials.

Carbon materials include various types such as graphite, activated carbon, and carbon fibers, and are widely used in applications such as the active material for the negative electrode of lithium-ion batteries, additives for conductive plastics, inks, and CFRP. Our company evaluates the structural differences of carbon materials through Raman analysis. In the case of carbon black (CB) and activated carbon, the G-band peak becomes broader compared to graphite, and the full width at half maximum increases. This indicates that the crystallite size differs, with graphite having a larger crystallite size than CB and activated carbon. **Differences in Raman spectra due to carbon materials:** - Graphite shows a strong and sharp G-band around 1580 cm-1. - It indicates the disorder in the hexagonal structure, which is the unit cell of graphite, and the stacking of layers is more disordered. - In CB and activated carbon, the G-band peak is broader compared to graphite, and the full width at half maximum is larger. - Graphite has a larger crystallite size than CB and activated carbon. *For more details, please refer to the PDF document or feel free to contact us.*

Many people may have questions like, "What can be done with IoT?" and "What is needed?" upon hearing the term IoT. Through digital communication, it is possible to obtain various information such as flow sensors, valves, circuit boards, and abnormal monitoring that were not accessible with traditional analog control. For example, by monitoring the valve opening, one can detect blockages in the equipment and identify leaks from cumulative flow. This information directly contributes to reducing downtime and improving quality through continuous long-term monitoring and knowledge-based management. Compatible models include those with digital communication via RS485, in addition to traditional analog controls like 0-5VDC and 4-20mA. (Older models such as the 58xxS, MfxxS series, SLA58xxS, and SLAMfxxS series). Even older models that do not support digital communication can be upgraded to the latest mass flow models, enabling digital communication. The dimensions between new and old models are the same, and no wiring changes are necessary. Additionally, we can provide control boxes for data collection from mass flow. This enables a "visualization" of small IoT without making large changes to the equipment.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. Many implementation examples are also presented, so please take a look at the case study page.
