Ball Lenses Category

Ball lenses are a popular choice in a variety of applications due to their ability to accurately focus and collimate light with minimal spherical aberration. These lenses are often utilized for laser collimation and focusing, as well as coupling between lasers, fibers, and detectors. One significant advantage of ball lenses is their cost-effectiveness and ease of mounting, making them a convenient choice for many industries. Additionally, sapphire ball lenses are highly durable and resistant to high temperatures and physical strength, making them suitable for use in a wide range of wavelengths from 200nm to 5.3μm. N-BK7, sapphire, and fused silica ball lenses are available upon request.

Custom Ball Lenses From Chineselens

A custom ball lens is a spherical lens that has been customized to meet specific optical requirements. Ball lenses are typically made from glass or optical-grade polymer materials and can be manufactured in a wide range of sizes and shapes to suit different applications. They are commonly used in optical instrumentation, fiber-optic communication, and laser systems.
The most common techniques to shape the ball lens are grinding, polishing, or precision injection molding. The material and size of the lens, as well as the required precision, will determine which technique is used.
Due to their spherical shape and high precision, we can use custom ball lenses to focus or collimate light highly efficiently. We can also use them to couple light into and out of optical fibers and for beam steering and imaging applications.

Frequently Asked Questions

Ball lenses have several advantages over other lenses, including their compact size, versatility, and ability to focus light to a point or create a collimated beam. They are widely used in a variety of applications due to these characteristics.

Ball lenses are used in a wide range of applications, including imaging, sensing, communication, and laser systems. They are also used in medical, scientific, and industrial applications. Some typical applications for ball lenses include microscopy, laser pointer, camera lens, and fiber optic coupling.


Yes, we can use the ball lens in high-power laser systems. However, high-power laser systems often require special lenses made from materials that can withstand the high temperatures and power levels generated by the lasers.

Ball lenses are typically packaged and shipped in protective cases or boxes to prevent damage during transport. The packaging should be designed to protect the ball lens from physical harm, such as impact, and environmental factors, such as moisture and dust. The ball lenses should be handled carefully during packaging and shipping to prevent damage.

The tolerance range for a ball lens refers to how closely the actual dimensions and curvature of the lens match the specified measurements. The tolerance range can vary between different manufacturers and affect the lens’s performance.

To select a reputable manufacturer or supplier of ball lenses, consider their experience in the industry, their reputation and customer feedback, their technical capabilities, and their ability to meet your specific requirements. It is also essential to carefully review their terms and conditions, including their warranty and return policy, before placing an order.
