Description
When the connector and the fiber remain stationary, the internal lens has five alignment degrees of freedom: linear alignment in the X and Y directions, pitch and yaw alignment angles, and adjustment of the Z-axis using both pitch and yaw. The travel range in the X and Y directions is ±0.7mm, the travel range in the Z direction is greater than 2 mm, and the pitch and yaw adjustment range is ±4°. It has good structural stability and high coupling efficiency. If the wavelength of the light source is changed, the collimator needs to be re-adjusted to achieve higher coupling efficiency.

Applications
- Used to launch or receive light in free-space optics experiments.
- Essential for beam shaping, alignment, and redirection in open-path setups.
- Collimate light from high-power multimode fiber-coupled diode lasers.
- Common in materials processing (cutting, welding, engraving) where a wider beam is preferred.
- Collimated beams are required for absorption, Raman, or fluorescence spectroscopy.
A large beam helps improve signal collection or sampling over larger areas. - Used to emit or collect light signals over longer distances with lower divergence.
Multimode fibers help deliver high-power pulses, while collimators shape the output. - Provides a controlled beam size for surface profiling, 3D scanning, or alignment verification.
- Enhances measurement repeatability and precision.
- Delivers uniform, large-diameter beams for illumination in endoscopy, photoacoustic imaging, or optogenetics.
- Multimode fibers allow for high-power, even distribution of light.
- Used in fiber-to-free-space and fiber-to-fiber coupling setups for testing optical components like filters, mirrors, or lenses.
- Provides bright, uniform light for inspection systems in manufacturing environments.
