The LBTEK Adjustable Focusing Collimator offers a compact design that simplifies free-space laser to fiber coupling. With an FC/APC connector, it provides improved return loss. The adjustable focusing collimator is available in three coating wavelength ranges: 350 nm-700 nm, 600 nm-1050 nm, and 1050 nm-1700 nm, and comes with focal lengths of 2 mm, 4.6 mm, 7.5 mm, and 11.0 mm. Each collimator is coated with an anti-reflection coating to reduce reflectivity. For detailed parameters, please refer to the specification table or curve data. The purchase includes the corresponding eccentric adjustment parts. LBTEK offers various customization services; for specific customization requirements, please contact LBTEK technical support.
