Aspheriacal Lens 

      Aspherical lenses are designed with a single element to help reduce the number of lenses found in multi-lens optical assemblies.

      In other words, unlike a conventional lens with a spherical front surface, an aspherical lens has a more complex front surface that changes curvature from the center of the lens to the outside of the lens edge.

       The reduction in the total number of components not only helps reduce the size or weight of the system, but also simplifies the assembly process.

The integration of aspheres into applications, such as the output of focused laser diodes, not only reduces the total cost, but also trumps components designed with conventional spherical optical lenses.

Customer questions & answers


Typical questions asked about products:

 -  Is the item durable?

 -  Is this item easy to use?

 -  What are the dimensions of this item?


Q1. How many days will samples be finished? How about mass products?

A1. Generally, we need about 7 days to finish the samples production. As for the mass products, it depends on your order quantity.


Q2. How can I get samples from you?

A2. Just send us your specifications and requirements, then we will send samples accordingly.


Q3. How do you control quality of your optical glass lenses?

A3. Optical glass lenses are processed in the vacuum dust-free workshop, the processing technology includes material preparation, milling and grinding, precision grinding, polishing, rinsing, edging, coating, inspection and agglutination.To guarantee high-quality of lenses, each processing will be inspected for three times.


Q4. Are you a factory?

A4. We have processing workshop in Xi'an city, Shaanxi province, China.
