Rod Lenses are cylindrical lenses with polished on its circumference surface. 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.

◦Focal length shortened by reducing the rod lenses diameter compared to cylindrical lenses.
◦Precise processing and polishing yields distortion-free, flex free straight line gain when projection is made from a distance.
◦Suitable for collecting large amount of light when installed it in front of a line sensor.

▶Please contact our Sales Division for rod lens with AR coating requirements.
▶Contact our Sales Division for customized products. (customized on outer diameter, length, etc.)
▶Use MLH-10 (Small Lens Claw) or MLH-SF (Selfoc® Lens Claws) to hold cylindrical lens.
W4021, W4051
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶Align the beam on the circumference surface for proper use.
▶Notable spherical aberration may occur due to the small curvature of rod lenses it is recommended that you use cylindrical lenses for precise optical systems. W3062
▶When diverging laser beam through rod lenses, operators’ eyes may be exposed to diverged beam. Make sure to check the power of laser and to apply safety goggles before using rod lenses.
▶Rod lenses are not chamfered use caution when handling the product.
