Long Distance Collimators For 300M FC/APC Connector 1200nm-1700nm

For laser collimation or coupling at up to 300 meters, we've carefully designed the collimating lens with a focal length of around 150 mm. This effectively collimates and shapes the fiber-emitted laser beam, yielding a high-quality beam with a larger beam. The lens uses an advanced multi-air-spaced lens design. It outputs a beam of extremely high quality (M² approaching 1) with minimal wavefront error, making it perfect for long-distance laser transmission and pulsed laser emission. Within the effective range, it ensures excellent collimation, with an approximately Gaussian energy distribution, a clear and sharp spot, and no obvious diffraction, thus enhancing laser performance.
