The manufacture of high-precision customized 2D fiber arrays together with MLA active alignment enables us to offer customized MLAs of high number functional channels with minimum deviating angle error of outgoing light rays.
A choice of suitable MLA is based on the customer requirement for a shape of outgoing light rays, type of fiber and the operating wavelength. The other end of fibers can be connectorized by E2000, LC, SC, FC, ST or by MTP® connectors. MLA with pre-determined fiber length can be housed in a stainless steel flange for easier implementation within targeted application.

We will propose for you, based on your request for parameters of outgoing light beam from the MLA, a suitable MLA. For the calculation we need to know following parameters:
A) Operating wavelength
B) Fiber type
C) Working distance
D) Beam width

Due to the precise active fiber alignment onto the matrix of aspheric lenses we are guaranteeing for all channels minimum insertion losses as well as minimum tilts and offsets of outgoing light beams. Used manufactured method as well as additional antireflection broadband coating ensures minimum losses due to reflections. Highpower variant is available upon request.
