Reliable Optics Depend on Reliable Metrology
For laser scientists, advanced metrology is about peace of mind. Choosing a supplier able to integrate manufacturing and metrology increases the likelihood of success for both scientific and industrial high-energy lasers. Make sure you get the technical data to ensure your optics perform under pressure before they enter the system. So what does metrology actually … Continue reading
Detecting Optical Communication Signals with Precision
Many optical communication systems operate in the near-infrared (NIR) and short-wave infrared (SWIR) ranges, where transmission efficiency and signal integrity are strongest. Detecting these signals reliably requires photodiodes that combine high sensitivity, low noise, and fast response times. InGaAs photodiodes and germanium photodiodes from GPD Optoelectronics are designed to operate across the 800–1650 nm spectral range, supporting … Continue reading
Detecting Patterned Wafer Defects with Dark-Field and UV Imaging
The Growing Challenge of Patterned Wafer Inspection Semiconductor wafer inspection has become a defining factor for yield, reliability, and time-to-market. As devices shrink, patterned wafer inspection becomes more difficult due to dense layouts and complex structures that reduce visual contrast. This enables critical defects to blend into intended features. Dark‑field inspection is an optical inspection … Continue reading
SO₂ Is in the Air and We Want to Know Where
Sulphur oxide (SOₓ) pollution from maritime transport now exceeds car emissions in many of Europe’s largest port cities. As industrial and transportation monitoring becomes more critical, the accuracy of our remote sensing technology must keep pace. In a recent published study, researchers investigated the “Effect of UV Scattering on Detection Limit of SO2 Cameras.” Their … Continue reading
New Low-Absorption Coating for Multi-kW CW Laser Applications
LASER COMPONENTS achieves low absorption values of less than 10 to 5 ppm. Due to the continued increase in laser power, particularly in industries such as manufacturing, medicine, and defense, optics with the lowest possible absorption are becoming increasingly important. This helps prevent thermal lensing or focus shifts and enables the highest possible laser-induced damage thresholds … Continue reading
