The TZB28 and TZB38 telecentric illuminators by Vision & Control are characterized by low divergence. Their illuminated field is either 28 or 38mm at a distance of 200mm, depending on the model. The two focal wavelengths (blue and IR) and three electrical connection variants (P-24V for transmitted light applications and HP-24V for incident light and SL) are available. The latter is suitable for both transmitted and reflected light. Depending on the variant, the brightness is fixed via an integrated controller, or it can be regulated via an external illumination controller.
Chromasens has introduced a 3D inspection system designed for detecting imperfections on the surface of metal cylinder heads requiring large field of views.
