Flat concave non spherical lens


describe

A plano concave non spherical lens is a special type of optical lens that has a flat surface and a non spherical concave surface. The design of this lens aims to provide better optical performance than traditional flat concave spherical lenses, especially in correcting aberrations and improving imaging quality. The design of non spherical surfaces allows lenses to focus or diffuse light more effectively without introducing additional optical aberrations.

advantage

  • High imaging quality: Compared with traditional flat concave spherical lenses, flat concave non spherical lenses can provide higher imaging quality, especially in edge imaging.
  • Optical performance optimization: Non spherical design allows the lens to more effectively correct aberrations, achieving optical performance optimization.
  • Flexibility: Suitable for a wide range of applications, from basic scientific research to industrial, medical, and consumer electronics fields, providing more design flexibility.
  • Simplify system design: It can reduce the number of lenses required in the system, as the performance of a single non spherical lens may be equivalent to a combination of multiple spherical lenses.

application

Flat concave non spherical lenses are widely used in various high-precision optical systems, including:

  • Imaging systems: such as cameras, telescopes, microscopes, and other optical imaging devices, are used to improve imaging quality.
  • Laser system: Used in laser beam shaping, laser scanning, and laser communication equipment to precisely control the propagation of laser beams.
  • Optical measurement: In optical measurement and detection systems, it is used to improve the accuracy and reliability of measurements.
  • Lighting system: Used in specific lighting applications to adjust the distribution of light beams to meet specific lighting requirements.

conclusion

Flat concave non spherical lens is a high-performance optical component that provides excellent optical performance and imaging quality through its non spherical design. The versatility and flexibility of this lens make it an indispensable part of many high-precision optical systems. With the advancement of optical manufacturing technology, the application range of flat concave non spherical lenses is expected to further expand. We provide customized optical solutions for optical systems by selectively transmitting and blocking light within a specific wavelength range. Its wavelength selectivity and high transmittance make it an indispensable component in optical system design.
