Lens Assembly

Optical lenses or optical system is a complex device with high requirements, which demands not only the combination of high-precision optical lenses and optical mechanical parts, but also professional assembly environment to ensure their key arguments, such as cleanliness, coaxiality, focal length, distinguishability and other indicators, are not affected, so as to achieve the best optical performances of the end product. Because of this, Oplens set up its own assembly department in 2021, which not only improves our production line but also can better meet the needs of customers for lens assembly. If you don’t have such a lens assembly environment or inspection conditions, we are capable to help you in this respect.  

What Processes are Involved in Optical Assembly Manufacturing?

Optical assembly processes may include mounting, alignment, precise optical pathway placement, beam manipulation, focusing, optical bonding, and sonic welding techniques.

Typical Optical Component Assembly Work Includes:

Bonding glasses & filters into wheels

Laminating glasses & filters

Product labelling & identification

Gluing glass to glass components

Mounting in screw mounts and holders

Gluing glass to metal assemblies

Press fitting glass lenses into housings.

Customization & OEM

Oplens Optics is a leading custom optical Lenses manufacturer. Most of our orders, including optical lenses and optical mechanics, come from customization. Oplens can custom optical Lenses based on your designs and requirements. After the completion of production and processing, optical components can be assembled into finished lenses by specialists in a professional assembly environment. This OEM optics model can save you time, energy and money to help you reduce costs of your optical products.  

The following shows the optical Lenses that we can customize:

Spherical Lens:


Oplens specializes in producing custom-made spherical lenses if they are not readily available in their inventory. Their product offerings include Plano-Convex, Bi-Convex, and Positive Meniscus lenses with positive focal lengths, as well as Plano-Concave, Bi-Concave, and Negative Meniscus lenses with negative focal lengths. Additionally, Oplens has the capability to apply custom optical coatings such as anti-reflection coatings to the surfaces of their lenses.

Aspheric Lenses:

Custom Aspheric Lenses

Aspheric lenses have unique advantages over spherical lenses. For example, they can improve optical quality, reduce optical components and design costs. They are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, CD players and high-end microscopic instruments.

Besides the above mentioned optical Lenses, we can also produces a wide array of custom optics, such as custom Optical Windows, IR Optical, custom optical mirrors, Ultraviolet (UV) Lens, ect.
