Ultra-broad-band Light Sources

Praevium has developed a broadband superluminescent diode (SLED) to improve the depth resolution of spectral-domain OCT measurement.  These fiber-coupled sources have also been used for spectroscopy. Our SLED products are sold through partner Thorlabs. Links are provided below.
