Why is Optical Metrology important?
Optical metrology is the study of measurement using light. It is often preferable to mechanical metrology due to its greater accuracy, versatility, and ability to profile delicate workpieces. An optician’s ability to finish an optical surface is often limited by metrology. Measuring the specific attributes of a lens to known certainties establishes lens quality, which creates value for the customer. Reliable inspection data, therefore, removes unknowns in optical system modeling and performance. At Optimax, we run a continuous improvement program for quality assurance to identify measurement uncertainties and minimize their impact upon optics inspection.
Art of Aspheres
Aspheres have one or more optical surfaces of non-constant curvature.
Manufacturing and metrology of complex aspheres is an emerging science for optical fabricators: Optimax leads the way in our investment in cutting-edge equipment and testing, research and training, and track record of performance on customer programs.
Learn more about our asphere metrology capabilities in our brochure.
Types of Optics
We apply our state-of-the-art optical and mechanical metrology solutions across the full spectrum of our product offerings, including our aspheric optics, cylinders, domes, freeforms, prisms, spheres, and so on. Refer to our high-precision optical components for more information.
Our approach to optical precision focuses on continual innovation and using the most specialized tools available. We have a suite of industrial metrology solutions to meet the most extreme measurement needs. These include: precision standard fizeau interferometers for irregularity measurements in spherical and plano surfaces; surface profilers for non-spherical surfaces (i.e. aspheres), and stitching interferometers to measure multiple zones on a lens surface, then mathematically stitch the data together to determine irregularity over the full aperture.
The new Optimax Metrology Laboratory provides the best possible environment for precision optical measurements. With extreme vibration isolation and temperature control, the facility is intended for measuring high-precision optical components to accuracies better than 50th wave. Additionally, specialized software tools that measure irregularity for comparison to a Zernike fit specification are available to optical designers for measurement analysis.

Lens design software analyzes optical tolerances by modeling a perturbed optical system to capture the effect of simultaneous changes in manufacturing and alignment errors.
Optimax Systems uses this MRF process to correct aspheric lenses in transmission to subwavelength errors.
Cylinder manufacturing methods can influence specification, offering recommendations on what to consider when designing cylindrical optical components to minimize cost and allow for greater flexibility in manufacturing.
There are parameters used in specifying centration of a lense and techniques used to check the location of and position the optical axis. Whether centering errors are specified in terms …
Prisms are optical components used to reflect or refract light. Their distinct characteristics give rise to its own language, the language of prisms.
One design strategy for an optical system is centering two or more lenses together to build a lens assembly. However, strain in excess may cause delamination or fracture of the …
Selecting the material from which a lens is made is a fundamental design consideration. In certain situations, a substitute or equivalent material may need to be identified depending on the …
This paper will define surface irregularity for spherical surfaces, offer information on measurement methods for testing surface irregularities, and some specification guidelines.
Mechanical attribute tolerances can be a major cost driver because of time and yield penalties added to fabrication of a lens. Dimensions and their tolerances are interrelated, so designers need …
Centration errors arise from deviation from superposition. In a perfectly centered lens, the mechanical and optical axes are concurrent and coincidental, superimposed on each other.
Mid-spacial frequency wavefront error, slope, and PVr have a big effect on optical component manufacturing. Specifying them can help reduce error.
Phase-shifting interferometry is widely used to determine form errors of an optical surface in optical manufacturing. These distortions can affect the ability to get accurate data on thin film coated …
This paper will first detail where slope error originated from, what it represents and the role it plays in the optical performance.
This paper examines the role surface roughness plays in optical system performance, discusses the components of a surface roughness specification, and contrasts roughness with cosmetic defects.
