Micro Sizes Rod Lens

Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. UNI Optics can provide the size from Φ1~Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to OEM customers upon request.



1. What is the Rod lens?



Rod Lenses are cylindrical lenses are polished on the circumference and ground on both ends. 


2. What are Rod lens used for?



These are used in several applications including laser focusing beam into a line, changing beam
shape into sheet-shape or irradiating at a distance with elongated line.
