| Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications. These lenses are manufactured from UV transmitting Fused Silica and are supplied uncoated. Anti-reflection coatings are available as listed earlier in this section. To order an anti-reflection coated lens simply append the wavelength in nanometers to the product number. These lenses may also be used as mirror blanks if a concave cylindrical surface mirror is required. |
