Spherical Lens For Cellphone Cameras

A spherical lens has at least one surface that refracts light to focus or collimate it. It is a simple, inexpensive lens useful for essential focusing and collimating purposes where high optical performance is not required. They have limited abilities due to their spherical shape but are easy to make and implement in simple optical assemblies. For precision and high-end applications, aspheric and compound lenses are typically used instead.

 

We offer high-quality spherical optical lenses for various optical applications requiring essential focusing or collimating performance. Our spherical lenses are an affordable, durable, and easy-to-integrate solution for simple optics assemblies, devices, and systems. Manufactured from premium optical materials like BK7 glass or fused silica, our lenses are precision ground and polished to provide smooth curved surfaces and minimize defects. Custom spherical optics with specific dimensions, tolerances, and coatings can also be provided on request.

 

Our spherical lenses are an ideal choice if you want to build simple and compact optical systems or devices on a budget. They provide reasonably good focusing power using a minimal number of parts and simplifying alignment. We have decades of experience manufacturing lenses and can deliver affordable, high-quality solutions to meet your needs.

Applications

The most significant applications of spherical lenses derive from their ability to provide elemental positive and negative refractive power in a simple, low-cost form. They represent a simple but essential lens shape for both science and technology. Some of the most popular applications are:

- Vision correction

- Camera lenses

- Magnifying glasses

- Microscope objectives

- Photographic projection lenses

- Fresnel lenses

- Laser optics

 

What are the benefits of spherical lenses?

Spherical lenses offer several benefits:

1. Low cost. Spherical optical lenses are inexpensive compared to more complex aspheric and compound lenses. They only require spherical grinding and polishing processes which are simpler than non-spherical surfaces. This makes them a cost-effective option for many basic optics applications.

 

2. Simple to align and integrate. Spherical lenses have rotational symmetry and do not require precise angular alignment within an optical system. They are also easy to insert into a lens housing or mount simply. This simplifies the integration of spherical lenses into optical instruments and devices.

 

3. Provide primary focusing power. Spherical lenses can adequately focus or collimate light for some purposes where high performance is not required. They can be used to build simple magnifying glasses, condensers, telescopes, microscopes, and more with good imaging quality.

 

4. Widely available. Spherical lenses are widespread optical components that many manufacturers produce. Many lens types, materials, focal lengths, diameters, and qualities are available at various prices. This range of options allows for cost and performance optimization.

 

5. Mature technology. The technology for designing, fabricating, and coating spherical lenses is very mature and straightforward. Processes have been developed and optimized over decades. This results in a robust solution where performance and quality are well understood.

 

6. Achromatic options available. Combining two spherical lenses of different materials can produce achromatic doublets that reduce chromatic aberration. Some limited correction of optical aberrations is possible using spherical lens designs.

 

However, spherical lenses also have some significant limitations:

• They suffer from higher optical aberrations like spherical aberration, which limit performance.

• They have a fixed focal length that cannot be adjusted or zoomed.
