Rod lenses are mainly used in sensors, light guides, endoscopes, and laser systems. Polishing can be applied to either the end faces or the cylindrical faces depending on the specific application requirements.
Rod lenses can feature two end faces polished or cylindrical faces polished, with various coating options available. Cylinder lenses can be provided with positive or negative focal lengths. Shapes include plano-convex, plano-concave, double-convex, double-concave, meniscus, achromatic, or custom designs.
Our optical components are widely utilized in laboratory equipment, four-wheel orientation systems, double beam holographic optical path systems, Fourier spectrometers, imaging systems, computers, holographic lighting, linear detector lighting, and laser collimators.
