YREMOptics offers various types of spherical lenses, including plano-concave, bi-concave, plano-convex, bi-convex, achromatic, ball, positive meniscus, and negative meniscus lenses.
- The primary benefits of utilizing spherical lenses in optical systems include their simplified surface design and reduced manufacturing expenses.
- Plano-convex and plano-concave lenses feature one flat and one spherical surface each, while meniscus lenses possess one concave and one convex surface. Additionally, bi-convex or bi-concave lenses comprise two spherical sides.
3. Bi-Convex Lenses are employed in finite imaging applications. They excel in producing positive conjugate image ratios ranging from 0.2 to 5 and are particularly effective when the object and image are equidistant from the lens.
4. Bi-Concave Lenses are employed to diverge collimated beams or expand light, resulting in a negative focal length.
Both spherical and aspherical lenses finds extensive applications in security systems, automotive technology, digital photography, laser equipment, optical instrumentation, and various other domains.
