VG-4
The VG-4 fiber coupler series from Phanos Technology is designed to provide stable, efficient, and flexible laser-to-fiber coupling for a wide range of Phanos laser sources. Supporting both single-mode (SM) and multi-mode (MM) fibers, VG-4 couplers are ideal for scientific, industrial, and OEM laser integration. Equipped with aspheric, biconvex, or plano-convex lenses, the VG-4 series accommodates different beam diameters and wavelength ranges, ensuring optimal coupling efficiency across visible and near-infrared spectral regions. An optional power attenuation function allows precise control of output power, making the VG-4 series suitable for sensitive optical setups.
