Article: Using Aspheric Optics In Complex Lens Designs

By Kent Weed, Vice President of Engineering

Optical design engineers often discuss the use of aspheres in optical designs to reduce element count, but as a whole, seldom put the discussion into real-time practice often fearing that the more complex fabrication process of the asphere itself overwhelms the advantages that they might gain. II-VI Optical Systems has successfully produced complex aspheres in the past and understands the trades and benefits.
