  • 消色差透镜

    An achromat is a lens consisting of two cemented elements made of different materials, usually flint glass with crown glass. The achromat offers superior correction of spherical aberration in monochro..

  • 平凹透镜

    Plano-concave lens has a negative focal length, diverges collimated incident light, and forms only virtual images which are seen through the lens. It is often used to expand light beams or increase fo..

  • 平凸透镜

    Plano-convex lenses have low spherical aberration. Use them with the plano side facing the point source or the focus and the curve side towards the collimated beam. In a Lens, the following parameter..
