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.

LBTEK stainless steel mount is used for installing Ø12 mm collimators, featuring 2 M4×0.2 precision adjusters without knobs but with locking nuts. The locking nuts are 6 mm hex nuts, adjustable with the MT-TW6 torque wrench. The collimator is secured by flexible spring plates and set screws. The 2 M4×0.2 precision adjusters without knobs but with locking nuts allow for pitch and yaw adjustment of the collimator using a hex key. The optical mount has M4 countersunk mounting holes on the side. The purchase of the LBTEK stainless steel mount includes hex socket ultra-thin head screws and a hex key.

LBTEK is suitable for mounting cylindrical optical components with a diameter of Ø12 mm, and can be installed in adjustment mounts with SM1 threads or adjustment mounts with Ø25.4 mm smooth bore holes, as well as in coaxial systems.
