Rod lenses These cylindrical lenses have very short focal lengths and large apertures, and are simple to mount. They are generally used to expand a laser beam into a fan of rays, so defining a plane and projecting a line onto any surface. For this purpose we also offer these mounted. The mount has a standard Tube Mount 25mm thread and attaches directly to our beam expanders and, via adaptors, to laser heads etc. It can be rotated and locked in the correct orientation.
