Designed for use in various laser and imaging systems, COE Optics’ rod lenses are polished on the circumference and ground on both ends, similar to a cylinder lens. They focus collimated light into a line and are available in diameters as small as 1mm. N-BK7 and UV fused silica substrates support UV, visible, and NIR applications. Ideal for rigid endoscopes, these lenses reduce vignetting and simplify assembly.
