From September 9–11, 2026, the 27th China International Optoelectronic Exposition, CIOE 2026, will take place at the Shenzhen World Exhibition & Convention Center, Bao’an. This year, GIAI Photonics will be exhibiting in two professional halls, each focusing on a different area of optical technology. 📍…
The choice between a metallic mirror and a dielectric mirror comes down to one trade: bandwidth versus reflectance. A metallic mirror reflects moderately well (roughly 90% to 98%) across an extremely wide spectral range and barely cares about angle of incidence. A dielectric mirror reflects…
Choosing a narrow bandpass filter manufacturer comes down to three questions: can their coating process hold your center wavelength tolerance across the full clear aperture, do they measure the filter under your actual angle and cone conditions, and is the blocking specification real across your…
Choosing a ZnSe lens manufacturer comes down to three things you can actually verify: the grade and traceability of the chemical vapor deposition (CVD) zinc selenide blank, the measured bulk absorption at your operating wavelength, and whether the polishing and coating processes hold surface figure…
