MgF2 Spherical Lens |
 |
| |
|
MgF2 Spherical Lenses are useful for a wide range of applications. Plano-concave, bi-concave, meniscus, plano-convexand bi-convex lenses are manufactured to exacting Shanghai Optics Laser Quality surface figure and surface quality specifications.
This high standard of quality provides exceptional performance in demanding applications. For high energy laser applications.For high energy laser applications, a 20-10 Shanghai Optics Laser Quality surface figured is highly recommended as its laser damage threshold is above 1J/cm2.
These lenses are manufactured from MgF2 for ultraviolet applications and are supplied coated or uncoated. Standard narrowband "V"-coat antireflection coatings are available, see ordering section below. When used to focus a collimated beam, the light should be incident on the curved surface of the lens. MgF2 lenses may be combined with other lenses to form complex systems.
These spherical singlet lenses are manufactured from UV Grade fused silica and can be supplied AR coated or uncoated.
Please call your Shanghai Optics sales engineer for pricing and delivery details.
