  • African Multi-span Bridge

    African Multi-span Bridge

    13 km, including a 260 m long main span, the bridge will also rank among the world's longest main-span balanced cantilever bridges. In August 2023, construction work on Mtentu Bridge commenced following a four-month ramp-up period. The Mtentu Bridge is a multi span box girder bridge, currently under construction, spanning the Mtentu River, near Lundini in the Eastern Cape of South Africa. The Mtentu Bridge forms part of the N2 Wild Coast road (N2WC) project, which aims to improve the travel time between Durban and East London. South African National Roads Agency Limited's N2 Wild Coast Toll Road (N2WCTR) serves as a shining example of a catalytic infrastructure project that combines socio-economic benefits and engineering ingenuity. The N2WCTR, which stretches from the Gonubie Interchange in East London to the Mtamvuna. The 6th October Bridge in Cairo, Egypt, takes the top spot with a total length of 20. Heavy freight trucks will shave hours off trips between Durban and East London.

  • West African Fiber Optic Collimator

    West African Fiber Optic Collimator

    We provide a full family of Gaussian beam fiber-optic collimators for coupling light into and out of fibers. Through detailed design considerations and proprietary high-return loss technology, these collimators exhibit extremely low beam distortion, low loss, high return loss . It is often necessary to transform the light output from an optical fiber into a free-space collimated beam. In essence, a simple collimation lens is all that is needed for this purpose. The beam's performance is governed by two primary parameters: 1) Beam Divergence.
