14-Channel 1550nm Microlens Array for Fiber Collimator
Coligh is a China-based manufacturer of fiber collimation microlens arrays. We provide customized design and production of one-dimensional microlens arrays for optical fibers according to customer requirements.
Microlens Array for Fiber Collimator Product Overview
Microlens arrays play an important role in fiber collimation, as they can simultaneously collimate multiple fibers. In multi-channel optical communication systems, they convert the divergent beams emitted from each fiber into parallel collimated beams. Microlens arrays can be used for coupling between laser sources, coupling between fiber arrays and waveguide arrays, and can also be applied in optical multiplexing and optical switching.
Coligh focuses on the production of fiber-coupling collimation microlens arrays. We currently offer a standard 14-channel one-dimensional linear microlens array for fiber coupling and collimation, and can also customize 4-channel, 8-channel, and 16-channel microlens arrays according to customer requirements.

The Application Of Fiber Collimator Micro Lens Array
The primary function of a fiber collimator micro-array lens is to convert diverging optical beams in an optical fiber into parallel beams, or to efficiently couple parallel light into an optical fiber. It has a wide range of applications:
- In DWDM systems, fiber collimator micro-array lenses can collimate the beams of multiple DWDM channels to receivers or OADMs.
- In optical networks, they are used for optical switching and optical cross-connects (OXCs) to perform optical path switching.
