Micro-Sphere Ball Lens 5mm Diameter Focal Length 4.37mm at 830nm

MS-08-4.35P2

Micro-Sphere Ball Lenses are mostly used for coupling optical fibers to laser diodes and other fibers or detectors.
◦Since these ball lenses are much smaller they are suitable for applications requiring reduction in size and weight. The lens circumference are completely polished and should be handled carefully to avoid damage
◦Both AR coated and uncoated are available. Single layer MgF2 is available in 3 variations of bandwidths 400 − 700nm, 700 − 900nm and 1300 − 1550nm.
◦Design wavelength of the focal lengths is 587.6nm (yellow helium line [d])

Guide
  • Please contact our Sales Division for micro lenses with AR coatings.
  • Contact our Sales Division for customized products. (customized on outer diameter, etc.)
Remark -
Attention
  • Micro-sphere ball lenses with anti-reflective coating are marked at its optical axis to identify the direction of coating. After installation, clean the ball lens by wiping with alcohol and check marks on the optical axis.
  • Small ball lens have a short focal length, so it is possible to focus the beam at a very large angle. However, since spherical aberration is large, the focused spot size will not be small.
