Meniscus cylindrical lenses

Description

These economical meniscus lenses provide a wide range of longer focal lengths at low cost. The 60mm lenses have moulded edges whilst the 25mm are edged and centred. Each lens has one spherical and one toroidal surface, giving zero power in one cross-section and positive or negative power in the orthogonal section. The overall effect is that of a conventional cylindrical lens.
