In professional projects, quality decisions rely on reliable data — especially when light must be designed, documented, and evaluated according to standards.
The LIGHTmetric® ONE is not a standard lux meter. It’s a high-end spectral radiometer delivering:

✔ Continuous full-spectrum measurement (360–830 nm)
✔ Precise CCT, Duv, and Δx/Δy color metrics
✔ Documented measurement uncertainty
✔ ISO-calibrated, traceable results
✔ Reliable illuminance data up to 350,000 lx

𝐖𝐡𝐲 𝐝𝐨𝐞𝐬 𝐭𝐡𝐢𝐬 𝐦𝐚𝐭𝐭𝐞𝐫?
Modern LED technology, dynamic spectra, and standards such as DIN EN 12464-1 require more than basic lux readings. Architects, lighting designers, consultants, and film professionals need spectral accuracy — not reconstructed approximations.
From architectural lighting validation and audit-ready documentation to precise color matching on film sets, LIGHTmetric® ONE provides data you can trust.

𝗢𝗻𝗹𝘆 𝘁𝘄𝗼 𝗱𝗮𝘆𝘀 𝗮𝗴𝗼 at the Izaña Atmospheric Observatory (2,370 m above sea level), freezing fog and strong winds coated our BTS Solar (www.gigahertz-optik.com/en-us/product/bts-solar) spectroradiometer in a thick layer of ice.

Extreme and rapidly changing weather conditions are not unusual at this high-altitude research site above the cloud layer. Rapid temperature changes, strong winds and supercooled fog can quickly form ice on exposed instruments – as you can see in the pictures.
During the period of particularly heavy icing, the movement of the system was temporarily stopped as a precaution.
The BTS Solar itself remained fully active and continued monitoring conditions.
𝗕𝘂𝘁 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝗿𝗲𝘁𝘂𝗿𝗻𝗲𝗱 𝘁𝗼 𝗻𝗼𝗿𝗺𝗮𝗹 𝗾𝘂𝗶𝗰𝗸𝗹𝘆:
As the temperature increased very rapidly, the ice disappeared just as fast.
The additional image shows the BTS Solar completely ice-free again — taken yesterday, only 24 hours later.
Our BTS Solar measures direct spectral solar irradiance and supports atmospheric parameters such as total ozone column (TOC) and aerosol optical depth (AOD).
High-altitude research sites like Izaña provide exceptionally clean atmospheric conditions—making them ideal for long-term solar radiation monitoring, even when winter briefly takes over.

Gigahertz-Optik's BTS-Solar – this time north of the Arctic Circle
Icy deployment at -40°C ❄️

North of the Arctic Circle, our BTS-Solar defies the harsh realities of the Arctic. In temperatures as low as -40°C, frigid air, and endless polar silence, it demonstrates the true capabilities of our technology.

Where every breath freezes and the snow crunches, the system has been operating reliably so far! – a stress test under extreme conditions and preparation for the next mission on the other side of the world – in Antarctica.

40 Years of Gigahertz-Optik - the second decade.

🎉 Success and Expansion – New Measuring Instruments, Series Production, and a Subsidiary in the USA

In the late 1990s, Gigahertz-Optik began series production, expanded its portfolio, and in 2001 founded its US subsidiary in Massachusetts, which remains successful and still enhances activities. This marked Gigahertz-Optik's international expansion, and it began to further conquer the global market for light measurement technology.
With the development of the first spectral systems, we laid the foundation for a new generation of light measurement technology.

Celebrate 40 years of Gigahertz-Optik with us. From the laboratory in Bavaria to the world.
