Smart Vision Lights’ TL305 on and off axis light, available from Stemmer Imaging, is designed for difficult blister pack inspection tasks, where diffuse lighting is needed to properly illuminate the transparent packaging and pocketed foil to ensure the product quality of pharmaceutical goods. The TL305 illumination increases the colour response of the camera. It reduces reflections, glare and ‘hot spots’. The challenge of inspecting clear gel caps against various backgrounds, including foil or clear, or multi-coloured products is less of a concern since the light has eliminated ‘halo’ reflection and blurred edge contrast. It is suited to any application incorporating a line-scan camera over a conveyor and is available in custom lengths and multiple LED colours/wavelengths.
