Nov 9, 2017: Exalos has expanded its portfolio of 840-nm Superluminescent LED (SLEDs) by introducing new high-power devices that can provide more than 20 mW of power.
These 840-nm SLEDs are especially suited for Medical Imaging applications such as Optical Coherence Tomography (OCT) and Fiber Optic Sensor applications thanks to their high output power and large spectral bandwidth. For SD-OCT applications, higher output power from the SLED allow for more asymmetric splitting ratios in the interferometer and therefore in lower losses for the received OCT signal, enabling higher acquisition speeds or higher sensitivity.
Higher-power SLEDs also help realizing surgical ophthalmic systems or multi-modal imaging systems where the OCT path is shared and therefore experiences higher losses. For fiber sensing applications, higher-power broadband sources are needed for longer-range systems. The 840-nm SLEDs can provide an output power of more than 20 mW from a single-mode fiber and a have 3- dB spectral bandwidths of more than 50 nm. The standard product is delivered in a 14-pin Butterfly housing with a monitor photodiode and an FC/APC connector. All devices are based on Exalos’ proprietary design.
These new high-power devices are in currently available for delivery. Exalos will be exhibiting these high power 840nm SLED devices at BIOS and PW in San Francisco January 27th to February 1st. Please stop by our booth at either BioS (8335) or Photonics West (1941) to discuss how these sources can benefit your applications and learn more about our other products.
