N: refractive index
R: radius curvature
These plano-convex cylindrical lenses are edged as circular shapes so they can easily be combined with other elements in an optical system. They 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.
