Chalcogenide glasses could now find a home in applications such as underwater communications, environmental monitoring and biological imaging
Advances in optical polymers coupled with developments in fabrication methods have led to more optics designers choosing polymer components over glass and metal optical parts – and its no surprise why. Lower cost, faster production, and less weight are just a few of the myriad advantages that polymer-coated optics lend manufacturers.

Harvard researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components

Researchers have combined freeform optics and a metasurface to deliver high-quality AR/VR glasses that are compact and easy to wear
Chalcogenides offer many advantages that legacy IR materials simply cannot match, but they do require a diamond-like carbon (DLC) coating so the optic can withstand the harshest environmental conditions. However, coating chalcogenides with DLC has been notoriously challenging and plagued by adhesion problems and coating defects. Until now.
In this whitepaper, we introduce a novel optical replication manufacturing method. We investigate the manufacture and measurement of freeform optics, explain how this high-precision replication manufacturing method works, and outline the benefits this manufacturing solution brings to OEMs and any organisation who wants to benefit from the inclusion of freeform optics at cost and at scale across their imaging applications.
In many of today’s industrial markets there is a continual push for product miniaturization. The M3 family of piezoelectric motion controllers offer unrivalled compactness helping product designers to achieve more compact solutions. Manufactured by New Scale Technologies, the M3 micro-stages and actuators are the smallest and most precise closed-loop positioning solutions available.
