Fused Silica Spherical Lens
Detailed introduction
Bi-concave lenses
Negative magnification
Focusing or optical imaging
Bi-concave lenses are useful for a wide range of beam expansion or negative imaging applications. These lenses are manufactured from UV transmitting Fused Silica and are supplied uncoated. Anti-reflection coatings are available are listed earlier in this section .To order an anti-reflection coated lens simply append the desired wavelength in nanometers to the product number. These bi-concave lenses may be combined with other lenses to form complex imaging systems.
