Product Description

General Introduction: Raytek's N-bk7 cylindrical lens is made of fine annealed glass and has a variety of shapes, both coated and uncoated. The rectangular, flat convex and flat concave cylindrical lenses reach the maximum on the Y-axis and x-axis, respectively λ/ 2 and λ/ It has 40-20 scratch pitting surface quality, and can be plated with a variety of multilayer anti reflective coatings. The circular Plano convex cylindrical lens has a scratch pitting surface quality of 60-40, which can be coated with a single layer of MgF 2 antireflective coating. N-bk7 is an excellent lens material for most visible and near infrared applications. It has high homogeneity, low content of bubbles and inclusions, simple and direct manufacture, and can provide excellent performance with economic cost..
