Types of Spherical Lenses and Their Uses

Introduction of Spherical Lenses

Spherical lenses are vital in optics, playing a key role in devices such as eyeglasses, microscopes, and telescopes. They are composed of transparent materials such as glass or clear plastic that allow light to be manipulated to form images. In this section, we take a closer look at the types of spherical lenses and their applications.

Explain OF Spherical Lenses

Spherical lenses and their applications:
Spherical lenses are made of transparent materials such as glass or clear plastic and are an indispensable component in optical instruments.

These lenses are transparent, allowing light to pass through them, creating refraction – the bending of light.

They are useful in various fields

1.Telescopes use spherical lenses to observe celestial bodies such as planets and stars.
2.Microscopes use them to magnify microscopic entities such as microorganisms.
3.Glasses use these lenses to correct vision impairments.
4.Peepholes use them to observe people outside the door.

Types of spherical lenses

Plano-convex lense

MOK Optics plano-convex lenses have a positive focal length and can be used to focus collimated ligh, Our plano-convex lenses are fabricated from N-BK7, UV fused silica, N-SF11,Germanium,Silicon etc.

Plano-concave lense

Plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used to balance out aberrations of other lenses in the system. MOK Optics provides plano-concave lenses fabricated from N-BK7, N-SF11, UV-fused silica, CaF2,ZnSe etc.

Biconvex lense / Double convex lense

MOK Optics bi-convex lenses are popular for many finite imaging applications, our biconvex lenses are fabricated from N-BK7, UV fused silica, N-SF11,Germanium,Silicon etc.

Biconcave lense / Double concave lense

The Biconcave Lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses.our biconcave lenses are fabricated from N-BK7, UV fused silica, N-SF11,Germanium,Silicon etc.

Meniscus lense

Meniscus lenses are used to decrease the focal length of another lens while maintaining the angular resolution of the optical assembly. These lenses are commonly used to achieve tighter beam focusing when paired with another positive lens.

Achromatic lense / Doublet lense

Achromat is a lens consisting of two cemented elements made of different materials. The achromate lense offers superior correction of spherical aberration in monochromatic applicaitons.
