  • Positive focal length
  • Converge incident light
  • Form both real and virtual images
  • Very close to the form minimizing spherical aberration for infinite conjugate applications

These simplest form lenses have flat surface on one side and spherical surface on the other. They are widely used in telescopes, microscopes, collimators, optical transceivers, magnifiers, condenser systems and eyepieces.

 

Plano convex lens made of UV FS (UV grade Fused Silica) and CaF2 (Calcium Fluoride) are also available for fast off-the-shelf delivery.

 

Lenses can be supplied coated. For required coating please refer to the COATINGS section. If you would like to order a coated lens, please note the code of the lens and the code of the coating in your request.

 

If you would like to order a range of lenses with different focal lengths, please have a look at our BK7 lens kit offers.
