Biconvex Lens Custom Optical Lenses

A biconvex lens means that both surfaces of the lens are convex. Its focal
length is positive and mainly for the function of focusing. It is commonly used
in imaging relay system and object imaging at finite conjugate distance. The
smaller the conjugate ratio is, the smaller the aberration will be.

Oplens can not only customize the common plano-convex lens of N-BK7 or fused
quartz, but also customize the biconvex lens of any glass material.

You are welcome to contact us for customized biconvex lenses.

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.
