Zoom Fiber Collimator VFC-6F18-PC-C

The LBTEK zoom fiber collimator is a universal fiber collimator with a focal length adjustment range of 6 mm to 18 mm. Its achromatic design makes it suitable for a wider range of application scenarios. To minimize losses caused by surface reflections, all lenses in the collimator are coated with broadband anti-reflection coatings on both sides. The anti-reflection coating wavelength ranges include 400-650 nm, 650-1050 nm, and 1050-1650 nm. The output end of the zoom fiber collimator features SM05 internal threads and SM1 external threads, allowing it to be used with other optomechanical components. When rotating the zoom or focus ring, the remaining parts do not rotate, ensuring that adjusting the beam size does not interfere with any connected components, thus providing excellent pointing stability.
