Description
The J10919 series FAC lens is an optical lens that collimates light spreading from a semiconductor laser (LD) in the fast-axis direction. LD have a large divergence angle in the fast-axis direction, so the output light cannot be efficiently used unless collimated. The FAC lens collimates light spreading from a LD into a narrow beam with a radiation angle of several milliradians (mrad) or less so that the diverging light can be efficiently utilized.
Features
Aspheric micro-cylindrical lens
Highly efficient utilization of light from LD bar
Small variations in characteristics allow mass production
Minimized smile and side lobes due to high-precision fabricating technology
