The monochromator is a tunable light source that delivers a range of white light to the device under test. It grants the user the ability to fine-tune the wavelength of light and deliver a wavelength that maximizes the thermoreflectance response for the materials under test. Since the
The Single-LED Illuminator (SLI) provides a single wavelength of light, supplied by an LED emitter and delivered to the Measurement Head light port by an optical fiber. The SLI can be used for both steady-state and transient measurements and is ideal for multiple test samples that are comprised of the same surface material or surface materials with very similar thermoreflectance properties.
The Multi-LED Illuminator (MLI) is a rack-mounted enclosure that contains up to 16 different LED emitters. The MLI provides a range of wavelengths of light to the Measurement Head, delivered by an optical fiber. The number of LED emitters and the wavelengths included are customizable, ranging from 365 nm to 850 nm. The MLI can be used for both steady-state and transient measurements and is ideal for test samples that contain multiple materials within the field of view.
