BK-7 Plano Convex Lenses

 

P26,Lenses,pconvex

These are the simplest form of lens having a flat surface on one side and a spherical surface on the other. They are also very close to the form which minimizes spherical aberration for infinite conjugate applications.

Our glass lenses are made from the best BK7 optical glass. We have a vast range of different diameters and focal lengths. The lenses listed here are standards. Please call if you do not see the lens you need. We have both larger and smaller lenses and many other diameters to choose from. However, we do try to keep these standards available for quick delivery. For very small lenses see the section on microlenses.

These lenses are offered uncoated or with our A55 broadband visible (425-675nm) multilayer AR coating. In addition we offer a wide range of standard anti-reflection coatings for other wavelengths. See our AR coatings.

 

 

Coatings facility

Our advanced optical coating facility is computer controlled to ensure the highest performance coatings and excellent repeatability.

Plano convex lenses are essentially best-form lenses when used at infinite or near-infinite conjugate ratios.  With their positive focal lengths they will converge incident collimated light and from both real and virtual images.  Plano convex lenses are often used in simple telescopes, collimators, and magnification or condensing systems.
