Description
Fixed Focus Collimator FFL Series
BEAMQ Fixed Focus Collimator Package FFL Series Products, are
pre-aligned to collimate fiber light from an FC/PC, FC/APC, or SMA
connector. Each collimation package is pre-aligned in factory to provide
maximum diffraction performance for wavelength range from 700nm to 2
µm. This collimator’s optimal performance will be got with designd
wavelength, while it also could be used at non-design wavelengths, this is
because of chromatic aberration of the aspheric lens, which causes the
effective focal length to have a wavelength dependence.
