Is engineered with a spring fitted optical lens housed within its mechanical structure. It serves to collimate the fiber - emitted light beam and can also be utilized for coupling spatial light into the fiber. By rotating the outer sleeve of the collimator, the internal optical lens can be precisely translated along the vertical axis direction, This translation enables the adjustment of the distance between the lens and the fiber enface, thereby achieving different light spot sizes. Once the optimal position is attained, the housing knurled locking ring can be employed to fix the regulator firmly

Premium aspheric adjustable design: enabling flexible focal length adjustment
Featuring high-quality aspheric lenses and precise adjustment mechanisms, our Adjustable Aspheric Collimator provides flexible focal length tuning within the range of 2.0mm to 11.0mm (model-dependent). The collimator employs AR-coated aspheric lenses optimized for three wavelength bands: 350-700nm (visible), 650-1050nm (NIR), and 1050-1700nm (extended NIR), each with a maximum reflection of less than 0.5%. The non-rotating lens cell design minimizes beam pointing error during adjustment, with pointing stability within 15mrad for 2.0mm focal length models and 1mrad for 11.0mm focal length models. The device is compatible with FC/PC, FC/APC, and SMA connectors, supporting single-mode, multimode and polarization-maintaining fibers for broad application versatility.
Precision manufacturing process:
Ensuring the stability of adjustment Our Adjustable Aspheric Collimator is manufactured using high-precision machining and spring-loaded assembly technology to ensure reliable performance. The aspheric lens is mounted in a stainless steel cell with custom-machined threading, enabling smooth, precise translation along the optical axis when rotating the outer barrel. The knurled locking ring applies force evenly to secure the adjusted position, preventing drift during operation. The collimator features tighter dimensional tolerances for improved pointing stability and reproducibility, with a dark band on the threading indicating the farthest recommended adjustment position to maintain performance specifications. All optical components undergo strict quality control to ensure diffraction-limited performance when used with compatible connectors.
Core performance advantages: Adaptation to dynamic optical scenarios
Ultraopto’s Adjustable Aspheric Collimator offers diffraction-limited beam quality, ensuring superior signal integrity for high-precision applications. The adjustable 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 features excellent mechanical stability with vibration resistance up to 10g RMS and operates reliably across a wide temperature range (-40℃ to 85℃). The compact design (ø12mm typical) enables easy integration into space-constrained optical systems. while the spring-loaded lens cell ensures consistent performance under varying environmental conditions.
