metrology White Papers
Laser Light Engine Output Stability
In this white paper, Dr. Iain Johnson, Lumencor’s Director of Technical Support, tests Lumencor’s laser-based CELESTA Light Engine for consistency, power, and stability using continuous wave illumination, pulsed illumination, and time-lapse imaging....
Spectral, Spatial and Temporal Optimization of Solid-State Light Engine Output
Specifications for illumination systems for biomedical imaging and industrial metrology generally converge on spectral, spatial and temporal light output characteristics. This article describes some of the ways in which solid-state Light Engines...
Fast Shaping Control of X-Ray Beams Using a Closed-Loop Adaptive Bimorph Deformable Mirror
High-speed adaptive correction of optics, based on real-time metrology feedback, has benefitted numerous scientific communities for several decades. However, it remains a major technological challenge to extend this concept into the hard x ray...
The S-Series | SR
The new general purpose interferometer. Fizeau interferometer for surface and wavefront metrology. 1-Megapixel imaging and 4 optical sources.
Precision Motion and How to Achieve It
Nanoscale motion requires fastidious attention to instrumentation, passive controls, and experiment design. Most users have experience in motion control within the sphere of the microscale. In this paper we discuss what needs to be considered in the...
3 Questions to Ask Before Buying Infrared Interferometry
Important considerations in obtaining infrared optical metrology, for measuring transmitted wavefront error, optical quality, and surface quality. The paper asks questions to help guide the reader in determining need, finding workarounds (if any),...
Atomic Force Microscopy Enhances the Nanoscopy Toolkit
Imaging and morphology represent a critical puzzle piece when trying to understand nanoscale structures, whether they are naturally occurring, such as viruses, or engineered structures, such as nano-antennas and photonic devices. In addition to...
Defining and Describing Surface Error
Controlling optical component performance requires well-defined measurement processes. Analysis software can help by guiding users through the steps of the measurement process (geometry fitting, filtering, and defining parameters) and by making it...
Extreme Metrology: Big Science Requires a Nano-perspective
Extreme metrology represents the cutting edge in technological demand from the material researchers, astronomers, and other physicists whose work demands nearly unattainable precision. Understanding the metrology loop means understanding not just...
Custom vs. Off-the-Shelf Solutions: Are you dreaming big enough?
Custom positioning solutions provide more leeway for innovation, and at far less cost, than many customers realize. Irrespective of whether the goal is a one-off solution or multiple units for a wider industrial instrument, an evaluation of standard...
Custom Lens Design and Lens Assemblies
Hyperion Optics specializes in custom optical system design, prototyping, and OEM lens assemblies. This one-page document contains details about our custom lens design and prototyping workflow, examples of lens design in our portfolio, and the...
Metrology for the Manufacture of Freeform Optics
Freeform optics are gaining popularity with lens designers and optical system integrators as a method to solve complex optical system design problems. Optimax has developed new freeform manufacturing techniques that have improved the capability and...
Noncircular in Perfection - Production Accompanying Measurement of an Asphere
Independent of the application, whether in satellite optics, video lenses or endoscopes - aspheres have already become indispensable in a wide range of highly versatile technical fields of application. Regardless of the system’s size, they all have...
A New Spectral Analysis System Designed to Measure High-Performance Thin-Film Optical Filters
The HELIX Spectral Analysis System was designed to address the limitations of most commercially available spectrophotometers when measuring high-performance thin-film optical filters. The system’s capabilities are four-fold: it is able to track...
Centration Measurement, Lens Alignment and Assembly of Infrared Lenses
The whitepaper describes special considerations for the measurement of infrared lenses and gives examples for the measurement, alignment and assembly of different kinds of infrared lenses.
Asphere Metrology: Options for Measuring Aspheric Lenses
This paper will outline the numerous metrology options for aspheres at Optimax, including how they work, any requirements, and what is specified with each method in an effort to help reasonably tolerance aspheres. Effects on the fabrication and cost...
