FemtoLine series thin plano-convex or plano-concave lenses are made of UVFS. Thin lenses are designed for applications with ultrashort femtosecond pulses and feature low group delay dispersion (GDD). Thin lenses are available uncoated, coated with anti-reflective or broad band antireflective coatings. Most of the thin lenses are available ex-stock for fast off-the-shelf delivery.
