Optical Coupler SMA905/FC Connector (Standard Product)
The BWT standard optical coupler is an inline fiber-to-fiber coupling device available with SMA905 or FC connectors. It features easy coupling and high coupling efficiency (≥90%) over a wide 600~1500nm wavelength range, supporting input/output fiber core diameters of 105/200μm, 200/400μm, etc. The brass, chrome-plated body houses SMA905 (CSM-xxx) or FC (CFC-xxx) interfaces, handling maximum CW input optical powers of 30W and 15W respectively, with overall lengths of 27±0.1mm and 23.5±0.1mm. Other wavelengths can be customized upon request. For optimal coupling, the fiber end-face reflection loss is neglected, NA(in) should be ≤NA(out), and coupling efficiency may vary between different mated fibers. Before laser operation, ensure that the side surfaces of the mated fiber connectors and the fiber end faces at both ends of the coupler are clean.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
The 850 nm and 940 nm infrared narrow‑bandpass filters launched by Innovation Photoelectric are core optical components specially designed for day‑and‑night security cameras. They effectively eliminate image interference during visible‑light and infrared‑illumination switching, delivering stable round‑the‑clock monitoring performance.
Within cutting‑edge ultrafast photonics research, asynchronous optical sampling (ASOPS) and synchronous sampling serve as fundamental technologies for terahertz excitation detection, coherent Raman imaging and other time‑resolved spectroscopy experiments.
