 Planoconvex Cylindrical Lenses - Circular Type

| Cylindrical lenses are primarily used for focusing or diverging light in a single plane. Our circular range of lenses are notably convenient to mount. The long focus lenses we stock are cut into a circular shape whereas the stronger lenses are mounted in a recess on a black anodised aluminium disk.
