Researchers find how to extend useable wavelength of chalcogenide glasses

Chalcogenide glasses could now find a home in applications such as underwater communications, environmental monitoring and biological imaging

Coating Polymer Optics: Perfecting the Science

This article is brought to you by: 

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.

New metasurface can tune laser light without additional components

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

The Solution to Coating DLC on Chalcogenides

This article is brought to you by: 

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.   

How to manufacture low-cost freeform optics for high-volume imaging applications

This article is brought to you by: 

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.

Photonic Solutions offering miniaturised rotary and linear micro-motion modules for smarter product development

This article is brought to you by: 

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.
