Description
Fiber Port Coupler with Aspheric Lens Collimator and 4.6mm, 7.5mm, 11mm EFL are sold for the same price
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.
NOTE: Price does not include the destination country's customs duties and value-added tax (VAT).

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.
