In pharmaceutical applications, especially during capsule inspection, monochromatic lighting is essential to detect defects like cracks, color variations, or contamination. These lights emit a single, specific wavelength—commonly in the green or red spectrum—to enhance contrast and surface irregularities that are not visible under standard white lighting. For such tasks, specialized monochromatic LED lights with high illuminance and a narrow beam angle are ideal. They are typically mounted above or below the inspection table and are compatible with 24V DC or 230V AC power. Surya Manufacturing or similar industrial lighting providers can supply monochromatic tube or panel-type lamps, engineered for accuracy, low heat emission, and continuous inspection workflows.
