Factory Custom Optical Aspherical Lens

Description

Aspherical lens are lens with a specially designed surface that can correct spherical aberration and improve imaging quality. Compared with traditional spherical lens, aspherical lens can better control the propagation direction and focusing effect of light.Aspherical optical parts can well correct various aberrations in optical systems and improve imaging quality. It can replace spherical parts with one or several aspheric parts, thereby simplifying the instrument structure, reducing costs and effectively reducing the weight of the instrument.In optical systems, aspherical lens are widely used to eliminate spherical aberration, coma, astigmatism, distortion, etc. Compared with spherical lens, aspheric lens can achieve higher optical quality and imaging performance. Therefore, aspheric lens have been widely used in some applications with high imaging requirements, such as optical instruments, photographic lenses, telescopes, etc.

Frequently Asked Questions

What are the advantage of aspherical lens?

Compared with traditional spherical lens, aspherical lens can better control the propagation direction and focusing effect of light.

What materials can aspheric lens be made of?

Aspherical lens can be fabricated using a wide range of materials including CaF2、BaF2、MgF2、LiF、ZnSe、ZnS、Ge、Silicon、BK7 Glass.

Which substrate and coating should I choose for an aspherical lens used in UV laser focusing (355 nm)?

UV fused silica is ideal for 355 nm applications—it has high UV transmittance and low thermal expansion. Pair it with a UV broadband AR coating to reduce surface reflection.

What are aspherical lens primarily used for?

They correct spherical aberration in lasers, imaging systems, consumer electronics, medical devices, and optical instrumentation requiring high precision.

How are aspherical lens tested before dispatch?

All lens undergo rigorous testing in our advanced metrology lab, including surface profile and aberration checks. Post-testing, they are cleaned and inspected for surface imperfections by the QA team to ensure spec compliance.
