UV transmitting Fused Silica
Anti-reflection coatings available for the UV
Concave side can be used as a reflector coating substrate
n :refractive index
R: radius of curvature
Plano-concave lenses are useful for 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.
