Cylindrical Lenses

BK7 Plano-convex Cylindrical Lenses
Plano-convex cylindrical lenses are useful for line imaging or uni-axial magnification in a wide range of applications. These lenses are manufactured from BK7 grade A optical glass 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 be combined with other lenses to form complex imaging systems.

BK7 Plano-Concave Cylindrical Lenses
Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications. These lenses are manufactured from BK7 grade A optical glass 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.
