About Illuminators
Illuminators are used to provide adequate contrast for imaging. Illuminators include backlights, LED illuminators, and fiber optic illuminators. Illuminators can be spot, dual spot, ring, line, dome, backlight and structured light types depending upon the nature of the illumination needed. Spot illuminators are ideal for emphasizing a specific feature on a part, de-emphasizes part background. Dual spot illuminators are used for inspection from a particular angle. Ring types are used to provide even lighting for cameras. Line type are also known as a linear array, these are used to provide even illumination along a straight line. Dome illuminators are used to provide extremely even, diffuse illumination. Backlights are used to provide maximum contrast between object and background. Structured light is basically with a diffraction grating that produces a characteristic pattern, such as a circle, square, stripes, etc.
