Good Quality Optical Glass BK7/K9 Half Ball Hemisphere Glass Lens

Item Number:X-P22B1T14001B

Half ball lens hemispherical lens is a hemispherical convex lens made of optical glass with good transparency and refractive parameters. They have high coupling efficiency and are easier to align than traditional lenses due to their physical shape.Due to the ease of installation brought by one plane, they are ideal for applications requiring more compact design, such as optical fiber communication, endoscope, microscope, optical pickup device and laser measurement system.VY Optoelectronics Co., Ltd. can provide half ball lens of various materials, such as BK7, Fused Silica, Sapphire, etc. Generally, the diameter is 1mm - 150mm

  • Material: BK7, sapphire, FS, Si, Ge, ZnS and so on
  • Diameter: 0.50mm-150mm
  • Tolerance: 0.001-0.003
  • Sphericity: 0.001
  • Surface Quality: 20-10 or better
  • Coating: Optional

   Half-ball (hemispherical) lenses feature a very short back focal length with the convenience of a flat surface for easy mounting.Half-ball lenses are easier to see and therefore easier to handle for physical applications. The lenses are very chemically stable and are great for severe environments, high temperature applications, and applications requiring high melting points. 

1) Half-ball (hemispherical) lenses are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.
