Germanium Alternative Gaining Momentum for IR Optics
Feb 23, 2018 — When it comes to designing IR imaging systems, manufacturers have traditionally worked with crystalline materials such as germanium. To make compact, lightweight systems, fabricators are driven to use aspheric surfaces, which has meant diamond...
Chalcogenide Glass Molding Advances Precision IR Optics
May 25, 2017 — Today, infrared optics are mainly used in relatively high-priced technical devices. Thermal imaging cameras, for instance, help builders and surveyors identify leaks and thermal bridges in buildings, while night vision systems are used by police and...
Sulfur Copolymers Boost IR Optics
TUCSON, Ariz., Aug. 15, 2014 — A new polymer made from sulfur demonstrates high transmission of IR light that could greatly enhance thermal imaging systems. While crystalline IR materials such as silicon, germanium, zinc selenide and halide salts are all frequently used for IR...
Engis Unveils New Polishing Process
HENLEY-ON-THAMES, England, June 19, 2014 — Engis has developed a new process for polishing a variety of laser-grade optical surfaces. The process uses diamond slurry and composite polishing plates to polish surfaces made of zinc selenide, zinc sulfide, germanium, silicon, calcium fluoride or...
IR Imagers More Affordable with New Ultrathin Lens
PARIS, May 22, 2014 — An innovative ultrathin lens could lead to more affordable IR thermal imaging cameras. The 1-mm-thick silicon Fresnel lens was developed by researchers from the French aerospace lab Onera, French thermal imaging sensor company ULIS, the Optical...
Photoactive Material Could Ease Dental Woes
VIENNA, May 1, 2014 — A visit to the dentist may not be the most fun experience, but a new material could make it more tolerable. A new generation of dental filling materials that harden more quickly under blue light has been developed by a team at the Vienna University...
Optical Nanocavity Boosts Light Absorption
BUFFALO, N.Y., SHANGHAI and SHENYANG, China, Feb. 27, 2014 — An optical nanocavity that boosts light absorption in ultrathin semiconductors could potentially improve solar cells and cameras, and maybe even harvest energy more efficiently. Currently in development by an international team from the University...
