Spherical lenses are the most common manufactured lenses in our facilities in Poland. We can offer all types of spherical lenses:
- Convex lesnes:
- Concave lenses:
- Meniscus lenses
– Plano-convex lenses
– Biconvex lenses
– Plano-concave lenses
– Biconcave lenses
As single lenses – spherical lenses give limited possibilities of optimization. As result they do not offer much flexibility in terms of correcting aberrations, so the images given by them are not perfect. However spherical aberrations can be minimized by optimizing ratio of curvatures’ radii.
Plano-convex lenses (PCX lenses) are the most basic optical element used for focusing and collimation.
Plano-concave lenses (PCC lenses) are the most basic optical element used for beam expansion and light projection.
Biconcave lenses (BCC lenses) are used for beam expansion and light projection while offering shorter focal lengths than plano-concave lenses. Biconcave lenses can be used independently as viewers and optical character readers.
Biconvex lenses (BCX lenses) are used for focusing and collimation while offering shorter focal lengths than plano-convex lenses. Biconvex lenses can be used independently as magnifiers and objectives.
Meniscus lenses (CX-CC lenses or concave-convex lenses) can be found most often in complex optical systems, where their function is to minimize aberrations and/or change the focal length of the system. Lenses of this shape are also a typical solution for corrective lenses worn in front of the eye and used to improve vision.
