What is a spherical lens?

A spherical lens, also known as a single lens, is an optical lens with a curved surface that converges or diverges light. They are widely used in imaging applications. Conjugate ratio, lens shape, radius of curvature, lens material, transmittance, wavefront aberration, scattered light, and type of coating are all features that must be considered when selecting a lens.

Types of Spherical Optics

There are two main types of spherical lenses: concave and convex. Concave lenses are thinner at the centre and thicker at the edges, while the opposite is true for convex lenses. At HS Optics, we routinely produce both types of spherical optics for a variety of imaging applications. The different formats we produce include:

Poly lenses are called convex lenses. It is thicker at the centre than at the edges. Convex lenses come in several shapes and sizes depending on how they look and work:

1. Plano-convex lenses

2. Double-convex lenses

3. Meniscus lens (concave-convex lenses) 

Concave lenses. Thinner at the centre than at the edges. Concave lenses can be classified as follows:

1. Plano concave lenses

2. Double concave Lens

3. Convex-concave lenses 

Application of Spherical Lens

Spherical lenses are widely used in medical optical imaging, laser field, scientific research, security monitoring, automotive industry, military equipment, aerospace and other high-tech fields.

1、Using array lenses for imaging, used in monitoring, microscope and other fields.

2、Correcting spherical aberration and optical aberration through glued lenses to achieve ideal image quality.

How should I choose a spherical lens?

Conjugate ratio, lens material, lens shape, radius of curvature, transmittance, wavefront aberration, scattered light, and type of coating are all characteristics that must be considered when selecting a spherical lens.

Spherical Lens Supplier

HS Optic is one of the leading manufacturers and suppliers of spherical lenses. Our spherical lenses are of high quality and competitively priced.With a wide range of machining equipment, HS Optics is committed to providing customers with high-precision optical system solutions, covering the complete manufacturing process from design, machining to assembly of various optical components and machinery.

We follow a step-by-step process and conduct rigorous quality checks throughout the process. 

Optical Design: Together, you'll design a lens that meets specifications, then begin production with near-net-shape optical glass blanks.

Forming and grinding: A diamond ring tool forms a radius on the glass blank. A series of progressively smaller diamond grinding wheels or loose abrasives finely grind the lens blank.

Polishing: The surface of the spherical lens is polished using bitumen or polyurethane pads and cerium dioxide slurry.

Testing and measurement: interferometry, surface roughness, radius of curvature, aberration, etc.
