Aspheric Optics

Trial and Tribulations of Optical Manufacturing: Asphere Edition

Optimax Systems, Inc., a leader in quick delivery prototype optics, has been manufacturing aspheric lenses for over 20 years. Along the way, we have learned many lessons, some the hard way, about how we overcame the problem, and provide takeaways for other manufactures and designers.   &nb ....

Specifying, Manufacturing and Measuring Aspheric Lens – Part I

This paper gives a basic survey of specifying aspheric forms, their function, and their manufacturing and testing

Specifying, Manufacturing and Measuring Aspheric Lenses – Part II

This paper highlights the similarities and differences between tolerancing, manufacturing and measuring spherical and aspheric surfaces

Basics of Optical Surfaces

Learn the fundamentals of tolerancing and testing for surface roughness and mid-spatial frequency errors. These factors affect all elements of the optics fabrication process, from design to manufacturing.

Practical Design Software Eases Asphere Manufacturability

Recent design methods and software advances make it much easier to design aspheric surfaces that actually work in production and test by considering manufacturability issues at the earliest possible stage in the design process

Asphere Manufacturing Considerations for the Designer

Aspheric glass lens modeling and machining

In this paper by Barry Johnson, the evolution of the manufacturing technology is discussed for a specific aspheric glass lens.  

Introduction to Asphere Metrology

This paper outlines the numerous metrology options for aspheres, including how they work, any requirements, and what is specified with each method in an effort to help reasonably tolerance aspheres
