Biconvex Lenses (BCX)
- For BK7A, the Design Focal Length @ 633nm
- For UV Fused Silica, the Design Focal Length @ 250nm
- Finite conjugate imaging , Focal Length: f = R / 2 (n-1)
Bi-convex lenses are useful for a wide range of finite conjugate or illumination applications. These lenses are manufactured from BK7A or Fused Silica. Lenses are supplied uncoated. These bi-convex lenses may be combined with other lenses to form complex imaging systems. Anti-reflection coatings are available. Please contact the Lambda’s sales team for more information about coatings.
