Fiber Coupling Microlens Arrays

Fiber Coupling Microlens Array Example

Description

PowerPhotonic’s fiber coupling microlens array products offer a wide range of configurations, focal lengths, and forms.  Using PowerPhotonic’s unique laser direct-write process, we can create a wide range of lens array optics without the need for a mask or mold tooling.

One-dimensional arrays are available with a standard lens pitch of 250µm, or can be supplied with customer-specified pitch.

Two-dimensional arrays are available with sphere, asphere, astigmatic, cylindrical or acylindrical lenses on a regular or customer specified grid.

The microlens array can be fabricated within a larger planar substrate to enable ease of mounting, without the mount impinging on the clear aperture of the microlens array.
