  • Have positive focal lengths
  • Converge incident light
  • Form both real and virtual images
  • Minimize spherical aberration as well as cancel coma and distortion at unit conjugate ratio

Biconvex lenses are all symmetrical, having equal radii on both sides. They are recommended for virtual imaging of real objects, and for positive conjugate ratios from 0.2 up to 5. For ratios outside of this range plano-convex lenses are usually more suitable. Biconvex lenses are used as magnifiers, objectives, some condensing systems.

 

Since both surfaces contribute to the power of biconvex lenses, they have shorter focal lengths than plano-convex lenses of equal diameter and surface radius.

 

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. We can also supply custom cutting, edging, coating or complete fabrication if required.

 

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