Rod lens / List of 5 manufacturers
What is a Rod lens?
A rod lens is a lens that has a cylindrical shape and the outer peripheral surface is polished with high precision. The cross section is basically a cut surface, but some are polished. As an optical function, the light radiated to the outer circumference can be converted onto a line and diffused in a fan shape. Often used for condensing purposes for equipment that requires light on the line, such as line sensors. The wavelength and focal length of light that can be handled vary depending on the material of the lens.
Application of Rod lens
Rod lenses have the effect of diffusing light over the line, which is also used as a lens for architectural markings and non-contact 3D shape measuring instruments. It is also placed in front of the line sensor on the factory production line and is used to take in light to make the sensor more responsive.
