Frequently Asked Questions

The Fixed Focus Aspheric Fiber Optic Collimator is used to collimate the light output by the optical fiber cable of FC/APC or FC/PC connectors, making it suitable for optical fiber coupling applications.

The collimator can provide typical wavelengths such as 405nm, 532nm, 543nm, 633nm, 780nm, 852nm, 980nm, 1064nm, and 1550nm according to customer requirements.

The aspheric lens in the collimator has chromatic aberration, and its effective focal length (EFL) is related to the wavelength, providing a diffraction limit at the design wavelength and a good achromatic effect.

To reduce surface reflection, both sides of each lens in the collimator are coated with antireflection films.

Yes, each collimator is pre-aligned before leaving the factory to ensure optimal performance.

The collimator has a compact structure design, making it convenient for integration and installation.

The focal distances for the collimator models range from 4.02mm to 18.4mm, depending on the specific model and wavelength.
