LPK: Image Grade N-BK7 Plano-Concave Lenses

LPK: Image Grade N-BK7 Plano-Concave Lenses

LPK: Image Grade N-BK7 Plano-Concave Lenses

Standard, low aberration beam expanding lens for most routine applications; 415nm to 1064nm. Well-suited to a wide range of beam expansion and aberration-balancing tasks in the visible and near-infrared, these N-BK7 plano-concave lenses reduce aberrations when used at near-infinite conjugate ratio. They are available in a wide range of standard focal lengths and diameters, with optional VIS & NIR broadband or Nd:YAG AR coatings.
