Vacuum Ultraviolet to Ultraviolet (VUV to UV) Plano-Convex Spherical Optical Lenses are available in select VUV Grade Magnesium Fluoride (MgF2) and VUV Grade Calcium Fluoride (CaF2) crystalline materials.
VUV to UV Plano-Convex Spherical Optical Lenses have one flat (plano) surface and one spherical surface curved outward (convex) to converge the VUV through UV transmitted rays from an object, thus forming a real or virtual image of that object. A VUV to UV Plano-Convex Spherical Optical Lens is used as a simple imaging lens to focus, collect and collimate VUV through UV light. VUV to UV Plano-Convex Spherical Optical Lenses have positive Effective Focal Lengths and are generally used as a focussing optical element within an VUV to UV optical assembly, VUV to UV instrument or VUV to UV laser.

Calcium Fluoride*: CaF2 exhibits good transmission properties from ~ 145nm Vacuum UV (VUV) to ~ 8.0um in the Infrared. CaF2 is a relatively soft crystalline material and care should be taken as CaF2 is sensitive to mechanical and thermal shock. CaF2 is a cubic single crystal optical material.

Magnesium Fluoride*: MgF2 exhibits high transmission properties from ~ 120nm Vacuum UV (VUV) to ~ 6.0um in the Infrared. MgF2 is a relatively hard crystalline material resistant to mechanical and thermal shock. MgF2 is a birefringent crystal typically oriented along the optical axis to avoid birefringent effects in windows & lenses.
