• Silicon lenses

  by benao ptics Feb 27
  Overview of silicon lens Silicon lenses are widely used in infrared applications, requiring optical elements with high thermal conductivity and low weight. Silicon plano-convex lenses are ideal for optical systems that collect, focus, or collimate light in near-infrared, short-wave infrared (SWIR),...

• Super-size High Precision Window

  by benao ptics Feb 27
  Bena Optics' ultra-large high-precision windows are primarily processed using large ring polishing machines. Bena Optics currently has the largest ring polishing machine with a diameter of 2 meters, capable of processing large windows with a diameter of around 1 meter while ensuring high surface acc...

• Wedge Prism

  by benao ptics Feb 27
  The wedge prisms can be used to individually deflect a laser beam by a certain angle or combined with another wedge prism for beam deviation purposes. A single prism can shift the incident beam by a specific angle. When two wedge prisms are used together, they can function as deformable prisms ...

• CVD ZnSe (Zinc Selenide) Window

  by benao ptics Feb 27
  Overview of CVD znse window CVD ZnSe windows are made from zinc selenide (ZnSe) material synthesized through chemical vapor deposition (CVD). ZnSe is a yellow-transparent polycrystalline material known for its high purity, strong environmental adaptability, and ease of processing. It exhibits ...

• Aspherical Lenses

  by benao ptics Jan 23
  Aspherical lenses do not have a simple spherical surface; instead, they have a rotationally symmetric, smooth, and continuous aspheric surface that conforms to a specific expression. This design allows light to travel through the lens in a more ideal path, thereby reducing aberrations and improving ...
