1550 nm Ultra-Long-Distance Collimator1000m

The 1550nm Ultra-Long Distance Collimator is a high-precision optical device specifically designed for long-distance transmission of near-infrared lasers. Utilizing a large-aperture, long-focal-length optical design, it converts the diverging laser output from an optical fiber into a collimated beam with a large spot size and low divergence angle, effectively reducing beam expansion during long-distance propagation. The product uses Corning SMF-28e single-mode fiber, with a central operating wavelength of 1550nm, a nominal beam waist spot diameter of 60.5mm, and a beam divergence angle as low as 0.034mrad, providing excellent beam collimation performance. This product is suitable for fields such as long-distance laser transmission, free-space optical communications, laser ranging, and optical detection, and can meet the application requirements of various high-precision optical systems for large-aperture, low-divergence laser output.
