Request InfoMahr Inc.Mahr Federal Inc. has released the MarSurf LD 130/260, a 2-D/3-D measuring station for checking contour and surface topography of aspheric optical lenses and other components during multistage grinding and polishing operations. The system offers a measuring range up to 260 mm, vertical resolution of 0.8 nm and form deviations of <100 nm. It can be used for spheric and aspheric lenses as well as many types of cylinder lenses, lens mounts, housing and other mechanical components. Measuring speed is up to 10 mm/s for large lenses and down to 0.02 mm/s for microlenses. For 2-D...See full productRelated content from Photonics MediaPRODUCTSPromoted Content February 2022 IssueOptical Products and Laser ComponentsDevelops and markets optical products and laser components, both standard and fully customizable.

Aspheres...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAspheric Lenses: Optimizing the Design: This second of two articles discusses the tools optical designers need to tailor their designs to the appropriate manufacturing process, optimizing the cost of component fabrication.With the understanding of aspheric lens manufacturing provided in part one of this article, designers have the tools to optimize their aspheres; the next step is to understand how to specify and...WHITEPAPERSPhotonics.com 6/1/2021Easy to use Computer Generated Holograms for Complex Surface MetrologyThere are many metrology methods on the market for testing aspheres.
