Combination 3-in-1 Lighting Module Reduces Machine Vision System Complexity and Cost

The Combined Tube Light reduces costs, maintenance, and setup complexity by merging tube, dark field, and bright field illumination into a single housing. It also removes the need for additional lighting units and linescan cameras, as well as the floor space for three separate inspection stations.

KONSTANZ, GERMANY, MAY 13, 2025 -- Chromasens, a member brand of TKH Vision, is now offering a Combined Tube Light LED linescan illumination system integrating three lighting setups into a single module. The Combined Tube Light reduces costs, maintenance, and setup complexity by merging tube, dark field, and bright field illumination into a single housing. It also removes the need for additional lighting units and linescan cameras, as well as the floor space for three separate inspection stations.


By deploying the Chromasens Combined Tube Light, images of the same object are acquired in three diverse illumination scenarios in a single pass. Each of these lighting setups captures different types of defects, from scratches and dents to size deviations and missing components, contributing to quality control and process improvement. These three lighting setups are:

• The tube light segment provides uniform, diffuse lighting for general imaging at maximum brightness of 1,000,000 LUX.
• The dark field segment enhances edge and surface defect detection by illuminating up to 800,000 LUX at low angles.
• The bright field segment achieves high-contrast, direct lighting for clear feature visualization at up to 12,000 cd/m2.

In industries where diverse inspection tasks demand adaptable, high-performance lighting solutions, such as manufacturing, electronics, or pharmaceuticals, the system's three-in-one capabilities are highly valued.

Each LED module of the Combined Tube Light operates independently to handle varied objects or inspection tasks. Modules measure a compact 170mm with the option of up to four modules being connected for a total length of 680mm. Fan cooling is standard although passive or water cooling is available on request. LED colors can be specified in White, Red, Green, Blue, and IR 850nm or 940nm.

The piCOBOT Electric vacuum generator

The piCOBOT Electric vacuum generator

Fully electric, slim design and absence of air-tubing and cabling. The new piCOBOT® Electric heads towards another success for Piab's piCOBOT® program. A secondary effect of these achievements is the absence of entangling air tubing and cabling. It simplifies the installation, and as the new piCOBOT® Electric only needs a single connection on the cobot arm, the clean set-up allows a completely unrestricted movement. The new piCOBOT® Electric package will contain plug & play software to fit UR e-series cobots, but many other useful adaptations will be introduced in the coming year
