To avoid reflections and mirroring, you need the right distance to the object, the right camera module and, above all, the right lighting. To be precise, diffuse lighting is required for code verification. Diffuse lighting is a uniform, soft light without shadows, contrast or extraneous light influences. This artificial indirect light is achieved using a diffuser (diffusing panel), which disperses the direct light before it reaches the product. For extremely diffuse lighting or DOME lighting, on the other hand, a matt white tube is used in the measuring chamber. Highly glossy surfaces are therefore no longer a challenge.

Objects from the medical technology or automotive industries often have complex 3D geometries that make it impossible to place the code to be checked directly on the code verification system. However, this is a decisive factor in achieving the goal of reproducible measurement results. A height-adjustable stand can help here. Installed in the stand, the code verification system can be precisely aligned with the product and the code can be read.
