We demonstrate a light source for multi-wavelength interferometry based on electro-optic single-sideband modulation. Engineered to address a myriad of applications across the UV, visible, NIR, SWIR, and MWIR spectral ranges, these emitters combine multiple wavelengths from 235nm to 4300nm in a single hermetic package for enhanced functionality and design simplicity. Each chip within the package is independently. Unlock exceptional illumination versatility with the Prizmatix CombiLED high-power multi-wavelength LED illuminator engineered for microscopy and a wide range of scientific applications that demand intense, precisely controlled light across multiple discrete wavelengths. The CombiLED Light Engine. Multiple LED sources can be efficiently combined into a single output beam, and offer major advantages such as long life-time, easily tunable spectrum, high power stability, and ultra-fast switching (on the microseconds level) without using moving mechanical components. Multi-Wavelength Collimated. Photoplethysmography (PPG) is a popular optical technology for heart rate monitors (HRMs) and peripheral capillary oxygen saturation (SpO2) measurements. It is simple and convenient because it requires only the attachment of an LED and a photodetector (PD) to the body. Featuring an advanced power supply controlled by a single-chip microcomputer, it can independently manage up to five LED heads. Single-wavelength interferometry achieves high resolution for smooth surfaces but struggles with rough, industrially relevant ones due to limited unambiguous measuring range and speckle effects.
