Description

• Focal length adjustment range: ±1mm
• Recommended for fiber coupling

Adjustable Aspheric Collimators 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 endface, 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.

Features：

Connecting fiber collimated output or coupling free space collimated light into fiber

Three Focal Length Options：4.5 mm、7.5 mm、11mm

adjustment alignment error < 15 mrad

Three Connector Options：FC/PC、FC/APC、SMA905

Threee AR-Coated Aspheric Lens Options：

400-700nm、650-1050nm、1050-1650nm

When used in combination with Ysenser's standard jumpers, it can improve coupling efficiency and ensure good repeatability.
