How to Manufacture Low-Cost Freeform Optics for High-Volume Imaging Applications
The benefits of implementing freeform optics are clear. They allow for custom aberration correction, redistribution of optical/mechanical tolerances, and even allow for a reduction in component count and system volume. In this whitepaper, Spectrum Scientific introduces a novel optical replication manufacturing method from Spectrum Scientific, Inc. for the manufacture and measurement of freeform optics, explains how this high-precision replication manufacturing method works, and outlines the...

Characterizing the temperature-induced evolution of the shape and texture of a silicon wafer
Using Linkam’s precision temperature control chamber with Sensofar’s Linnik objective lens eliminates these problems and allows accurate measurement of 3D topographic profiles of nanoscale materials. S neox 3D optical profiler with a Linnik...
Surface Characterization of Tribological Coatings: Wear Properties, Thickness and Roughness
With the S mart 3D profilometer, it is possible to more precisely measure the volume loss of the wear tracks after the friction and wear tests, since it measures the real shape of the wear track. There are many parameters that are important to study...
New Telecentric Optics with Liquid Lenses Technology
Anyone familiar with telecentric optics knows very well that the depth of field can be a problem when using high-magnification lenses. Most of the time you either end up using oversized optics or having to move the object or the lens to compensate....
Advantages of Grisms
What is a grism? A grism is a compound optical element composed of a GRating and prISM(s). It is a dispersive element that permits an in-line optical layout by cleverly exploiting the differences between gratings and prisms.
