BK-7 Biconvex Lenses
* Symmetrically convex positive lenses
* Focal lengths from 6.4 to 300mm
* Diameters from 5 to 100mm
* Anti-Reflection coatings available
* For additional sizes see Micro Optics
Symmetrical biconvex lenses are most useful when dealing with finite conjugate points. This makes them ideal for 1:1 imaging applications or for use in multi-element systems.
