Micro-Epsilon Group Circular Sensor for Structured and Metallic-Effect Surfaces colorSENSOR CFS2-M11

With the circular sensor, the light emitted by the controller is sent as an illuminated ring at an angle of 11° or 34° (depending on type) to the surface of the object to be tested. The diffuse back reflection (surface color) of the sample is detected by the sensor at 0° (parallel) to the surface and transmitted to the controller via an optical fiber. The ring illumination makes it possible to detect the diffuse color reflex regardless of structure or reflection. The sensors are available with different illumination angles and different spot sizes. Therefore, it is possible to measure colors with a repeatability of ΔE ≤ 0.3 in relative terms up to a working distance of 100 mm. Other sheaths and cable lengths are optionally available. The circular sensor opens up new fields of application for the colorSENSOR CFO product series. Combined with the high performance of the CFO series, the ring illumination provides even more precision due to uniform illumination. This compact combination can be universally used but is also suitable for special solutions (customer-specific adaptions). The homogeneous illumination mainly offers advantages on strongly structured or shiny-metallic surfaces while providing highest precision when distinguishing colors such as white shades. The circular sensor offers many advantages in terms of performance and installation possibilities. Due to the external controller, less installation space is required at the measuring point. Due to the standard FA connection, the optical fiber is also compatible with other controllers (previous series such as LT or WLCS).
