Product Description

Collimator with adjustable focal length, FC/PC connector
Operating wavelength 350 nm-1700 nm
Aspheric lens design with aspherical aberration correction

The fiber collimator is a commonly used passive optical component in fiber optic signal transmission, capable of converting the divergent light from the fiber output end into collimated light (parallel light) through an internal aspheric lens. LBTEK's rotatable and focus-adjustable fiber collimator includes models with FC/PC fiber connectors, designed for use with single-mode fiber patch cords. It offers rotatable and focus-adjustable collimators with anti-reflection coatings covering ranges of 350 nm-700 nm, 600 nm-1050 nm, and 1050 nm-1700 nm. Additionally, the rotatable and focus-adjustable fiber collimator features a spring and knob mechanism, making focal length adjustment simpler and more convenient, allowing for quick positioning of the collimated state. LBTEK also provides various customization services, including special dimensions, design wavelengths, output beam diameter specifications, and more. For specific customization requirements, please contact LBTEK Technical Support.

Rotary adjustable focus collimator, FC/PC connector

Connector: FC/PC
Focal Length: 4.5 mm
Internal Lens: Aspherical Lens

The rotary adjustable collimator provided by LBTEK features a compact structure and simple, convenient adjustment, making it easy to collimate fiber output light. With an FC/PC interface, the adjustable collimator currently offers three coating wavelength options: 350 nm-700 nm, 600 nm-1050 nm, and 1050 nm-1700 nm. All adjustable collimators are coated with anti-reflection films to reduce reflectivity. For detailed parameters, please refer to the parameter table or curve data. LBTEK provides various customization services. For specific customization requirements, please contact LBTEK Technical Support.
