FAC Lenses
Product Details
Fast axis collimating (FAC) micro-lenses are aspherical glass cylindrical lenses with excellent collimating properties. FAC micro-lenses are used to collimate the laser beam in the fast axis in
high power diode lasers (HPDL). Typical wavelengths are 808 nm, 940 nm and 970 nm.
How Does It Work?
A FAC lens with a high numerical aperture enables one to collimate the light of such a divergent beam. In this context, a short focal length (<1 mm) is advantageous to realizing a compact design
of the laser module. The original brilliance of the laser source can be maintained only by using an aspheric lens, for which the aspheric contour accuracy must be better than 1 ?m.
The accuracy of the fast axis collimation lens is a critical factor for the performance of the whole optical laser system. Any imperfection in the fast axis collimation lens cannot be compensated
for by the following optical system. FAC lenses from SCHOTT Advanced Optics are diffraction-limited and maintain the beam characteristics of the laser bar. Any lower lens quality results in a
significant loss of power output.
