LDX: Image Grade N-BK7 Biconvex Lenses

LDX: Image Grade N-BK7 Biconvex Lenses

Standard, low aberration 1:1 imaging lens for most routine applications; 415nm to 1064nm. Well-suited to a wide range of finite imaging tasks in the visible and near-infrared, these N-BK7 equi-convex lenses minimize aberrations when used at 1:1 conjugate ratio. They are available in a selection of standard focal lengths and diameters, with optional broadband VIS & NIR AR coatings.
