7ch Multi-Color Multi-position ring illumination
IMAR series type 7ch Multi-Color illumination that can illuminate from fine positions from high to low angles with a single unit for visual inspection, printing inspection, and defect inspection.
7ch Multi-Color NEO dome illumination
The IDDA-KH series type 7ch Multi-Color illumination, which uses hemispherical inner surface reflection to provide uniform diffuse light, suppresses halation that tends to occur with direct light on uneven or glossy surfaces, and produces a uniform image without shadows.
Capable of capturing curved surfaces and stepped workpieces as flat images
Wavelength characteristics (reference values)
It covers from the ultraviolet region to the infrared region beyond the visible light band.

Contrast between irradiation light and workpiece color
While the role of general lighting is to “brighten”, lighting in the field of image processing is to “highlight” the item to be inspected and to capture the “best image for image processing”.
The two colors on opposite sides of the hue circle are called “complementary colors,” and using complementary colors with the greatest difference in hue has the effect of making each other’s colors stand out.
The relationship between wavelength (lighting color) and work color, taking into account the general complementary color relationship, is as follows.
