首页 Fiber Accessories Fiber optic components Fiber collimator Adjustable focus non spherical fiber collimator (focal length 4.5/7.5/11mm) Adjustable Focus Aspherical Fiber Coupler 400-700nm (Focal Length: 4.5mm, Waist Beam Diameter: 0.86, FC/APC)

    • Adjustable Focus Aspherical Fiber Coupler 400-700nm (Focal Length: 4.5mm, Waist Beam Diameter: 0.86, FC/APC)

    The design uses a spring-mounted optical lens inside the mechanical parts, which is suitable for the output of a fiber-optic beam collimator and can also be used for fiber-to-fiber coupling. By rotating the outer sleeve of the collimator, the internal optical lens can move back and forth along the optical axis direction, thus adjusting the distance between the lens and the fiber end face to obtain different spot sizes.

    产品特点Three anti-reflection coating aspherical lens options: 350-700nm, 650-1050nm, 1050-1620nm、 When used with compatible connectors, it can achieve diffraction-limited performance、 Alignment error during adjustment <15mrad
