Ball Lens or GRIN Lens?
Both ball and GRIN lens types
can be protected against back reflection losses, but what distinguishes one over
the other? Ball lenses can be much smaller than GRIN lenses, leading to reduced
package sizes. At DSI, we have coated ball lenses as small as 250 microns. The
cost of ball lenses is also less than that of GRIN lenses. However, up to this
point, the GRIN lens has been heavily favored, and been employed in higher-end
systems more frequently. What will work best for your application?
