Fused Silica Plano Concave Lenses |
|
|
|
|
|
These simple
negative lenses have many uses. Alone they form a virtual image of a distant
object or collimated light source. Used in combination with other optics they
reduce the power of the system. Negative lenses are often quite thick. Sharp
edges which are common in negative lenses are removed by beveling in order to
reduce the likelihood of chipping. These UV grade synthetic fused silica
lenses are provided uncoated - however a wide range of standard anti-reflection coatings is available for these
lenses. |
