1064nm Long-Distance Collimating Lens

The 1064nm Long-Distance Collimating Lens is designed to collimate and shape the output from optical fibers, providing diffraction-limited performance for lasers emitted through various fiber connections at the designed wavelength. The collimation distance can reach up to 200 meters. This series of collimating lenses has a compact structure that is not affected by misalignment. The design incorporates aberration correction and uses an air-spaced double-lens configuration, ensuring excellent collimation results. The effective focal length of the double-lens is wavelength-dependent, so it is recommended to use this series of collimating lenses at the designed wavelength for optimal performance.

Product features：Fiber Collimator with FC/APC, FC/PC, or SMA Connectors、 Can be used for wavelengths from 405 nm to 1.55 μm.、 Simplified coupling of free-space laser to optical fiber、 Double-lens design, aberration correction performance、 Non-magnetic stainless steel housing

Dimensional Drawing

Beam waist spot diameter: Measured at the 1/e² point of the Gaussian beam, using theoretical values calculated for single-mode fibers at each wavelength.
Beam far-field divergence angle: Input is based on single-mode fibers at each wavelength, with theoretical calculations based on the 1/e² point of the Gaussian beam. Tolerance: +0.01° / 0.0°.
