Getting The Best Results From NIR Measurements
By Frederick G. Haibach, Bayspec

Near infrared measurements (700 to 2500 nm) usually are made in transmission and reflection, used to probe the molecular structure and composition of materials. NIR is preferred over mid-infrared when measurements need to be made at a distance, or with little or no sample preparation. 

Introduction To Silicon Photomultipliers (SiPMs)
By First Sensor AG

Silicon photomultipliers (SiPMs) are radiation detectors designed with extremely high sensitivity, high efficiency, and very low time jitter. The technology is based on reversed biased p/n diodes, making them capable of direct light detection ranging from near ultraviolet to near infrared. 

FLIR Thermal Cameras Help To Reduce The Invasiveness Of Cochlear Implant Surgery
By FLIR

The surgical placement of cochlear hearing implants behind the human ear requires a highly trained surgeon and can result in facial nerve damage, meningitis, tinnitus, infections, cerebrospinal fluid leakage, and potentially more.

Lens Manufacturers: Do You Know The Best Test For Lens Performance?
By Kevin Urben, Image Science

A high-quality lens begins with a good design, tolerant to small manufacturing errors. The manufacturing process must be tightly controlled, from individual lens elements to final assembly. But, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is necessary.
