Multi-LED Illuminator

The Multi-LED Illuminator (MLI) is a 2U rack-mounted enclosure that contains up to 16 different high-power LED emitters. The MLI provides a range of wavelengths of light to the T°Imager® Measurement Head, making it possible to achieve excellent results for a variety of samples and surface materials. Although the MLI does not have a monochromator’s fine-tuning capability, it provides a diverse range of light wavelengths, enabling users to optimize measurement results based on their test setup. The MLI can be used for both steady-state and transient measurements. Each LED has its own SMA connector and delivers its light to the T°Imager® Measurement Head light port via an optical fiber.
