Rod Lenses are highly polished small diameter rods made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces rods (or fibers) with precise diameters and unsurpassed surface quality. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a line.
We supply optical rod lens, specification of our rod lens as follow:
