Aspheric Optics

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

Fabricating freeform multispectral-ZnS corrector lenses

For more than 100 years, optical imaging systems were limited to rotationally symmetric lens elements, due to limitations in processing optics. However, the present application of CNC machines has made the fabrication of non-rotationally symmetric lenses, such as freeform surfaces, economical

Incorporating VIBE into precision optics manufacturing process

The VIBE™ process is a full-aperture, conformal polishing process that has the potential to be introduced in areas of today’s modern optics manufacturing process

Tolerancing an Optical Freeform Surface

Freeform optical shapes or optical surfaces that are designed with non-symmetric features are gaining popularity with lens
designers and optical system integrators. Tolerances on a freeform optical design influence the optical fabrication process

Make it like you use it

Testing and correcting the aspheric lens as it is used in transmission addresses some of the shortcomings of traditional 3D surface metrology. 

Profit through predictability: The MRF difference at Optimax

In an effort to reduce variation and improve predictability, Optimax integrated magnetorheological finishing into its aspheric lens manufacturing process. 

The sum of all errors: Technical Digest

The geometry of machines used to center lenses and to measure centering error all work in terms of the wedge case. Two important considerations are the centration of the lens and the difference in edge thickness. 

Trial and Tribulations of Optical Manufacturing: Asphere Edition

Optimax Systems, Inc., a leader in quick delivery prototype optics, has been manufacturing aspheric lenses for more than 20 years. Along the way, we have learned many lessons and provide takeaways for other manufacturers and designers

Specifying, Manufacturing and Measuring Aspheric Lens – Part I

A basic survey of specifying aspheric forms, function and manufacturing and testing

Specifying, Manufacturing and Measuring Aspheric Lenses – Part II

The similarities and differences between tolerancing, manufacturing and measuring spherical and aspheric surfaces are important

Asphere Manufacturing Considerations for the Designer

There are many topics to consider during aspheric lens design, including geometrical restrictions that hinder producing particular aspheric shapes. Understanding these restrictions will help drive cost. 

Aspheric glass lens modeling and machining

The evolution of the manufacturing technology for a specific aspheric glass lens can provide significant image quality improvement, reduction of the number of lens elements, smaller size, and lower weight. 

Introduction to Asphere Metrology

There are numerous metrology options for aspheres, including how they work, requirements, and what is specified with each method in an effort to tolerance aspheres
