首页 Fiber Accessories Fiber optic components Fiber collimator Long distance collimated lens (collimated distance 200m) 780nm long-distance collimating lens

    • 780nm long-distance collimating lens

    The fiber output can be collimated and shaped for different laser outputs from fiber connections, providing diffraction-limited performance at the designed wavelength with collimation distances up to 200 meters. The design of this series of collimating lenses is compact and unaffected by misalignment. During design, image aberration correction is applied, and a double-lens series with air spacing is chosen for excellent collimation performance. The effective focal length of the double-lens is wavelength-dependent. Therefore, this series of collimating lenses should be used at the designed wavelength for optimal performance.

    产品特点Fiber Collimator with FC/APC, FC/PC, or SMA905 Connectors、 Usable for wavelength range from 405 nm to 1.55 μm、 Simplifies free-space laser-to-fiber coupling、 Double-lens design with aberration correction

    Beam waist spot diameter: Taken at the 1/e² point of the Gaussian beam, calculated using the theoretical value for single-mode fiber at each wavelength.
    Far-field divergence angle of the beam: The input uses single-mode fiber for each wavelength, with the divergence angle calculated according to the theoretical value of a Gaussian beam at the 1/e² point.
    Tolerance: + 0.01° / 0.0°
