Rod lens
A Rod lens is a special type of cylinder lens, and is highly polished on the circumference and ground on both ends. Rod lenses perform in a manner analogous to a standard cylinder lens, and can be used in beam shaping and to focus collimated light into a line. Our rod lenses play a key part in many laser and imaging optical assemblies, and can be used for UV, visible and NIR applications.
Designed for use in a variety of laser and imaging systems, these components are available in a range of micro sizes for integration into a host of OEM applications. Custom sizes, variations in polishing/ ground surfaces and additional coatings are available upon request, please contact our Sales Department for details.
