References and examples from previous work:
Laser Phosphor Light Source
A white light source with superior luminance was developed by focusing blue laser diodes being focused on a phosphor converter element. This technology can achieve luminance levels that are significantly higher than those of the most powerful LEDs. These light sources are suited for coupling into light guides or other Etendue-limited applications.
In the light module shown the converted wavelength spectrum is coupled with a blue LED channel to keep the color temperature of the light source at a constant value.
Broad-range Fluorescent Imaging Light Source
Fluorescence microscopy requires powerful light sources that cover a broad spectral range. Modern light sources using LEDs or laser-pumped phosphor light sources often have spectral gaps in the wavelength range around 480 nm. To circumvent this, a light module was developed by using customized and optimized converter materials. A sophisticated thermal design is allowing a long lifetime without degradation of the phosphor, even under the high intensity of the laser pump light.
Example 3: NIR Light Source
Near-infrared spectroscopy, material characterization or microscopy require infrared light sources covering a broad spectral range. We are developing light sources in the NIR range that achieve high light output through the superposition of various LED emitters and remote phosphor technologies.
