Dropping of resin particle LumisisMarker droplets onto the liquid surface.

Visualizing the shape changes of the liquid surface and the liquid mixing process! Introducing a visible light source with purple 405nm and ultraviolet light.

We visualized the shape change of the liquid surface and the mixing process of the liquid when a droplet containing a red LumisisMarker was dropped onto a liquid surface containing a blue LumisisMarker. Under visible light source (purple 405nm), the LumisisMarkers appear red and blue, and the interface between the droplet and the liquid surface glows in the same color as the visible light source. Under invisible light source (ultraviolet), the LumisisMarkers appear red and blue, but the interface was not visible. Although fluorescent dyes become cloudy in the mixing area, the LumisisMarkers can be tracked because the fluorescent colors of the particles are different. 【Features of the visible light source (purple 405nm)】 - When using a color camera, halation can be removed through image processing. - The behavior of each particle can be captured. - When using a monochrome camera with an optical filter that passes wavelengths longer than 405nm, halation is removed, but the two types of particles are captured as the same color. - When using a bandpass filter, it is possible to capture the behavior of one color of particles. *For more details, please refer to the PDF document or feel free to contact us.
