LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Single-mode fiber-output divergent light collimated conversion
FC/PC and FC/APC fiber connectors available
Multiple wavelengths available from 405 nm to 1690 nm

The fiber collimator is a commonly used passive optical component in fiber optic signal transmission, which can transform the divergent light from the fiber output end into collimated light (parallel light) through the internal achromatic cemented lens. LBTEK fixed fiber collimators include two types of fiber connectors, FC/PC and FC/APC, and are used with single-mode fiber jumpers. They offer multiple wavelength options from 405 nm to 1690 nm, with an outer shell thread size of M11×0.5. Additionally, the fixed fiber collimators undergo collimation testing and individual alignment at their specified wavelengths to ensure excellent collimation performance within the anti-reflection coating wavelength range. Please note that due to the fixed design, this fiber collimator is not recommended for fiber coupling. LBTEK also provides various customization services, including custom special dimensions, design wavelengths, and output spot diameters. For specific customization requirements, please contact LBTEK Technical Support.
