Right Angle Prism is deviating or deflecting a beam of light with 90°or 180°. It is often used in telescope, periscope and other optical system. Deviate Beam or Image by 90° or 180° Material: N-BK7, UV Fused Silica, CaF2, ZnSe, or Ge AR-Coated, HR coated are Available

Note for Spherical Lens: a. Other optical glass materials from Schott, Ohara, Hoya or Chinese CDGM, UVFS from Heraeus, Corning, Germanium, Silicon, ZnSe, ZnS, CaF2, Sapphire are also available upon request . b. Custom-made Spherical Lenses at any size from diameter 1.0 to 300mm are available upon request.

Positive meniscus lenses is convex-concave lens thicker at the center than at the edges. They are used to minimize spherical aberration. When used in combination with another lens, it’s will shorten the focal length, and increase the NA of system.

Negative meniscus lenses is convex-concave lens thinner at the center than edges. They increase the divergence of the beam without introducing any significant spherical aberration. When used in combination with another lens, they will increase the focal length, and decrease the NA of the system.
