CaF2 Vacuum UV Bi-Concave Lenses
商品货号:ECS000860
商品品牌:Thorlabs
详细介绍
  • Material: Vacuum Grade CaF2
  • Wavelength Range: 180nm - 8.0μm

Thorlabs CaF2 Bi-Concave lenses are popular for many applications. Bi-Concave lenses have a negative focal length and are best used to diverge a converging beam. Similar to a Plano-Concave lens, a Bi-Concave lens can diverge a collimated beam to a virtual focus as used in a Galilean type beam expander (see Drawing tab for reference).

Lens kits are available. Please click here for information.
