    • 840nm 5mW SLD Laser Diode

    The SLD (Superluminescent Diode/SLED) light source combines the high output power of a laser diode with the broad spectral width and low coherence of an LED. Its narrow active layer, similar to that of a laser diode, makes it ideal for fiber coupling, giving it characteristics between those of an LD and an LED. The AS8B series is an SLD module developed for Optical Coherence Tomography (OCT) light sources and non-coherent optical measurement equipment.

    Product features：Broad spectral output；Polarization-maintaining fiber coupling；Low coherence；High stability；Intelligent control

    Part Number：MP-SLD-840-5-A81-14BF-PA

    Application area：Optical Coherence Tomography (OCT) | Fiber-optic Gyroscopes | Fiber-optic Sensing | Device Testing | Biological Detection
