Narrowband filters are a critical technology for LiDAR, laser cleanup, chemical and gas sensing, and more. Because creating multicavity filters is a challenge for deposition process control systems, Alluxa uses a computer-controlled variation on the turning point method of thickness control for each individual layer.

Gentec EO explores the many uses of laser wavelengths in this application note. Topics explored include common laser wavelengths in telecommunications, which wavelengths are needed and used for laser eye surgery, and how wavelengths are applied in laser welding applications. 

Free-space optical communication (FSO) is a rapidly developing technology that offers high-speed, secure, and reliable data transmission over long distances.

Zygo collaborated with Diamond Light Source (DLS) in the U.K. to install a deformable mirror with deformation feedback provided by Zygo’s ZPS sensor system. The system was installed in the B16 Test Beamline at DLS as a proof of principle for this application.

Non-contact sensing is invaluable in applications where measurements may be rendered unacceptably imprecise by slippage and poor speed management, or equipment or products may be damaged by contact.

Since the beginning of digitization at the end of the 20th century, the development of networks has been dominated by one topic: bandwidth. Where once telephone, data, and moving images were transmitted across different paths, triple play has now become widely accepted.
