For laser collimation or coupling at up to 300 meters, we've carefully designed the collineating lens with a Foca length of around 1 50 mm, This effectively collimates and shapes the fiber-emitted laser beam, yielding a high-quality beam with a larger beam. The lens uses am advanced multi-air-spaced lens design It outputs a beam of extremely high quality (M' 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, und no obvious diffraction, thus enhancing laser prefinance.

Optimized for 300m transmission: Achieving precise mid-range transmission
Our 300m Long Distance Collimator is designed with an optical system specifically optimized for 300m transmission, achieving ultra-low beam divergence (0.043-0.075mrad) to minimize beam spread over the target distance. The collimator uses a long focal length lens (136-154.2mm) to produce a collimated beam with a waist size of 22.89-34.8mm, ensuring sufficient signal intensity at 300m. The fiber core is available in single-mode (9μm) and multimode (50/62.5μm) options, optimized for the 1200-1700nm spectral range with ±30nm bandwidth. The optical path is precisely calibrated to ensure maximum coupling efficiency at the 300m target distance.
Precision manufacturing process: Ensuring mid-range stability
Our 300m Long Distance Collimator is manufactured using precision alignment and encapsulation technology to ensure consistent performance over 300m. The lens is made from high-purity fused silica with an ultra-smooth surface (Ra <0.1nm) to minimize light scattering, which is crucial for mid-range signal preservation. The collimator features an AR coating optimized for the 1200-1700nm range. The reflection loss is reduced to below 0.3% and the transmission efficiency is enhanced. The housing is made of corrosion-resistant aluminum and precisely machined to ensure mechanical stability, while internal damping materials reduce vibration-induced beam deviation. The standard connector is FC/APC, with SMA-905 available as an option for specific system compatibility.
Core performance advantages: suitable for 300m mid-range scenarios
Ultraopto's 300m Long Distance Collimator offers outstanding mid-range performance with beam divergence strictly controlled between 0.043-0.075mrad, ensuring precise beam delivery at 300m.
