doricTM acylindrical FAC lens
design 01 - long working distance
The Fast-Axis Collimation of laser diodes and laser diode bars requires lenses with aberration-free performance at extremely high
numerical aperture. With the recent fine tuning and advancement of our acylindric lens manufacturing technology, we are now proudly
offerring sidelobes-free FAC lens for NA of up to 0.80. Our cylindrical and acylindric lenses are already well-known for its excellence, but
with the latest product quality improvements we believe that we are offering the highest quality FAC lens available on the cylindrical
microlens market right now.
