BICC-C: Laser Grade Biconcave Lenses, N-BK7

BICC-C: Laser Grade Biconcave Lenses, N-BK7

BICC-C: Laser Grade Biconcave Lenses, N-BK7

Laser quality diverging and expanding lens for high energy laser and performance-critical applications; 400nm to 1550nm. Well-suited to a wide range of light expansion tasks in the visible and near-infrared, these N-BK7 equi-concave lenses are precision polished to ensure best wavefront quality and low scatter. They are offered with a large selection of optional high energy AR coatings.
