MEMS-VCSEL Swept-Source Laser Engine for OCT

Our partner Thorlabs is now selling 1310nm and 1050nm MEMS-VCSEL Swept-Source modules, along with full OCT systems utilizing the MEMS-VCSEL as the optical source.  The MEMS-VCSEL module makes unprecedented resolution and imaging speeds available to researchers. The module is designed specifically for high-speed, high-resolution imaging via swept-source OCT (SS-OCT). This widely-tuned laser output has been shown to have a coherence length of over 200 meters , enabling long-range OCT imaging.

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.
