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

Lenses for glasses and cameras 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 very thin films, so we observed them from a 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 microscope observation, SEM observation, and EDX analysis *For more details, please refer to the PDF document or feel free to contact us.

For transparent materials such as glass and ITO! Measurement evaluation of various transparent resins before and after UV exposure is also possible.

We offer a service for measuring the haze value (haze) and total light/diffuse transmittance of transparent materials (transparent films/sheets, glass, ITO, etc.). We use a haze meter device to measure the degree of haze and the degree of light diffusion. The results are expressed as the ratio of total light transmittance (T.T), which includes both the parallel component (P.T) and all diffuse components, to the diffuse transmittance (DIF), which excludes the parallel component. In addition to providing this service, we also offer data analysis and considerations from a molecular structure perspective.

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 rich in color, necessary functional characteristics, artistic qualities, and design elements for the product's application are imparted. However, yellowing (discoloration) may occur due to the environment in which they are used, potentially compromising those characteristics. By quantifying transparency and color not through human visual 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 the light source passes through the transparent sample, and within the integrating sphere box, data on the transmitted wavelengths (transmittance) and converted color space data is 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 materials for the negative electrode of lithium-ion batteries, additives for conductive plastics, inks, and CFRP. Our company evaluates the structural differences of carbon materials using 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 sizes are different, 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 disruption of the hexagonal ring structure, which is the unit cell of graphite, and that the layered structure is more disordered. - In CB and activated carbon, the G band peak is broader compared to graphite, with a larger full width at half maximum. - 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.*

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot in my car..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel including the controller and switching power supply (24V) is required when using the departure warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
