BK7 Plano-Concave Lenses are designed to enhance optical systems by reducing spherical aberration, coma, and distortion. These lenses have a concave surface on one side and a flat surface on the other. While the output rays do not converge to a single point, they appear to diverge from a virtual image located on the object side of the lens. This unique design makes plano-concave lenses highly effective in various applications.

Key Features:

  • Superior aberration correction: The plano-concave shape of these lenses helps minimize spherical aberration, coma, and distortion, resulting in improved image quality.
  • Versatile compatibility: Available in various diameters (Ø6, 10, 12.7, 25.4, 30, etc.), these lenses can be easily integrated into different optical systems.
  • Optimal orientation: The curved surface of the lens should face the object when used at a distance or infinite conjugate. In high-energy laser systems, the orientation should be reversed to eliminate virtual focus possibilities.
  • High-quality construction: Made from BK7 optical glass, these lenses offer excellent optical properties, including high transmission and low scattering.


  • Imaging systems: Plano-concave lenses are commonly used in imaging systems to correct aberrations and improve image quality.
  • Laser systems: These lenses find applications in laser systems to shape laser beams, correct aberrations, and control beam divergence.
  • Microscopy: Plano-concave lenses are utilized in microscopy setups to enhance imaging performance and reduce aberrations.
  • Optical instruments: They can be integrated into various optical instruments, such as telescopes, cameras, and projectors, to improve overall optical performance.
