Cylindrical Rod Lens Optical rod lenses are optically precise ground devices, a cylindrical lens with its circumference surface polished. Used for laser focusing into a line,changing beam shape into sheet-shape,or irradiating at a distance with elongated line. Focal length shortened by reducing the rod lense diameter compared to cylindrical lenses. Distortion-free, flexion-free, straight line gainable when projection was made at a distance, by precised process and polishing. Suitable for higher power applications without distortion.   1.

Distortion-free, flexion-free, straight line gainable when projection was made at a distance, by precised process and polishing. 5. Suitable for collecting large sum of light into sensor by putting it right in front of line sensor   Worldhawk can offer cylinder Lenses include convex cylindrical lens, concave cylindrical lens, meniscus cylindrical lens, and doublet achromatic cylindrical lens ect.
