Long Distance Collimator The fiber optic beam can be collimated and shaped for different lasers output through fiber optic connections, providing diffraction-limited performance at the design wavelength, with a collimation distance of up to 200 meters. The structure of this series of collimators is compact. Aberration correction is performed during design by selecting an air-spaced doublet lens series, which has excellent collimation effect and ability to couple space light. The effective focal length of the doublet lens depends on the wavelength. Therefore, this series of collimators should be used at the design wavelength for optimal performance.

Ultra-Long-Range Collimator Designed for ultra-long-distance applications, this collimator boasts an impressive collimation distance surpassing 1000 meters. It ensures the laser beam maintains high collimation throughout extended transmission, minimizing energy divergence and concentrating energy effectively. This significantly boosts laser transmission efficiency and positioning precision.
With a focal length exceeding 300 mm, the collimator excels at focusing spatial lasers. Its precise focusing mechanism enables efficient coupling of more laser energy into optical fibers, perfectly suiting demanding scenarios like long-distance diffuse reflection testing.
Featuring a 100-mm large aperture, the collimator facilitates smooth passage of increased laser energy, substantially enhancing the system's luminous flux. Besides augmenting laser power and intensity, the large aperture optimizes beam imaging quality and reduces wave aberration, providing robust support for overall system performance enhancement.
