Product Description

Operating wavelength 400 nm-1700 nm
Silicon-copper structure with advantages of high strength and high hardness
Achromatic doublet design with achromatic performance
High precision: Lateral displacement 0.2mm per revolution

A fiber collimator is a commonly used passive optical component in optical fiber signal transmission, which converts the divergent light from the fiber output end into collimated light (parallel light) through an internal aspheric lens. LBTEK's adjustable fiber collimators include models with FC/APC fiber connectors, designed for use with single-mode fiber patch cords. They offer adjustable collimators with anti-reflection coatings in the ranges of 400 nm–700 nm, 700 nm–1100 nm, and 1100 nm–1700 nm, featuring a housing diameter of 12 mm. Additionally, the rotatable adjustable fiber collimators employ an achromatic design, enabling collimated output across multiple wavelength bands and ensuring excellent collimation performance within the anti-reflection coating wavelength range. LBTEK also provides various customization services, including custom sizes, design wavelengths, and output spot diameters. For specific customization requirements, please contact LBTEK technical support.

High-precision rotatable focus collimator, FC/APC interface

Interface: FC/APC
Focal Length: 4.5/7.5/11 mm
Internal Lens: Achromatic Doublet Lens

LBTEK offers high-precision rotatable and focus-tunable collimators with a compact structure, simplifying free-space laser-to-fiber coupling. With a rotational precision lateral displacement of up to 0.2 mm per revolution and an FC/APC interface to enhance return loss, the focus-tunable collimators are available in three coating wavelength ranges: 400 nm–700 nm, 700 nm–1100 nm, and 1100 nm–1700 nm. Focal lengths of 4.6 mm, 7.5 mm, or 11.0 mm can be selected. Each focus-tunable collimator is coated with an anti-reflection coating to minimize 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.

The adjustable focus collimator is installed in the corresponding lens mount.
