Objective

Built specifically for color measurement over large surfaces, this fiber optic probe combines illumination with detection to measure reflected light and precisely monitor color.  The sophisticated design features built-in rejection of specular reflections off glossy surfaces and insensitivity to the embossing of the product.

Characteristics

• A built-in xenon flash lamp illuminates the sample 0 degrees from the surface normal
• Seven detection fibers spaced evenly around the probe are positioned at 45-degree angles from the surface normal to detect reflected light
• The second set of circumferential fibers detect reflected light from an internal white surface that serves as a real-time compensation channel for the source lamp

Benefits

Inline color measurement of materials with large surface areas illuminates and measures reflected light while ignoring the brightness of glossy surfaces.
