Zoom Fiber Collimators

Its focal length a dustmen Rane is from 6nmn to I8mm, During the adjustment process, it can maintain a might levees collimation of the light beam, ensuring that the collimation accuracy is not affected when the beam size is changed. This collimator has a precise zoom function and can also perform high-precision adjustment of the divergence angle of the emitted collimated light, enabling the light beam to be focused at any position between the maximum waist distance and the closest focusing distance of0.3m, ensuring that the free-space laser beam is coupled into the optical fiber with ahigh coupling efficiency. As a universal device, it is applicable to a variety of application scenarios, effectively reducing the time cost for users to screen for suitable fixed-focus fiber collimators, The design based on the air-gap lens makes it awe lower aberrations compared with aspheric lens collimators, with the Mf2 factor closer to I. smaller wavefront errors, and high-quality and stable light beam output

Premium zoom design: Achieving flexible focal length adjustment

Featuring an air-spaced lens design and a high-precision zoom mechanism, our Zoom Fiber Collimators provide an adjustable focal length ranging from 6mm to 18mm, allowing for flexible beam size control to meet various application requirements. The collimator employs high-quality optical lenses with a low wavefront error (typically λ/10 at 633nm), ensuring superior beam quality compared to aspheric lens collimators. The zoom mechanism features precision gears and guides for smooth focal length adjustment, with pointing stability maintained below 1mrad for FC/PC/APC connectors and <4mrad for SMA 905 connectors during zooming.


Precision manufacturing process: 

Ensuring zoom stability Our Zoom Fiber Collimators are manufactured using high-precision machining and alignment technology to ensure consistent performance across the entire zoom range. The collimator incorporates three broadband AR coating options optimized for different spectral ranges: The wavelength ranges are 400-650nm, 650-1050nm and 1050-1650nm, each with a maximum reflection of less than 0.5%. The housing has internal SM05 threading and external SM1 threading, compatible with ø1/2" and ø1" lens tubes, facilitating easy integration with standard optical mounts. The closest focusing distance is 0.3m, allowing flexible use as both a collimator and coupler.


Core performance advantages: Adaptation to dynamic optical scenarios

Ultraopto's Zoom Fiber Collimators feature a high numerical aperture (up to 0.25) and nearly Gaussian output from single-mode fibers, ensuring excellent beam quality. The variable focal length design eliminates the need for multiple fixed-focus collimators, saving time and cost in multi-application setups. The collimator delivers low insertion loss (≤0.3dB) and high return loss (≥55dB), minimizing signal attenuation in optical systems. It offers excellent off-axis performance for large multimode fibers and supports both collimation and coupling modes, enhancing versatility. The compact design fits inside any ø1.2" mount for easy system integration.


Full-scenario application coverage: 

Empowering flexible optical systems Our Zoom Fiber Collimators are widely applied in research, testing and industrial fields. In optical test equipment and laboratory setups, they provide flexible beam adjustment for prototype verification and multi-parameter testing. For dynamic optical systems such as adaptive optics and laser scanning devices, they enable real-time focal length optimization. In laser communication and sensing systems, they offer adjustable beam size for different transmission distances. The collimator also finds use in educational equipment, optical instrumentation and custom optical setups, delivering reliable performance for diverse dynamic applications.
