News & Innovations

New: Watch our Gigahertz Optik Company Video
Light accompanies our everyday life in the most varied of facets. The most diverse applications in the UV-VIS-IR spectrum require light sources or measuring systems to optimize the well-being of people in rooms, to promote self-sufficient plant growth, to advance future technologies in autonomous driving and much more. Thanks to our DAkkS accredited testing and calibration laboratory (ISO / IEC 17025 / DAkkS D-K-15047-01-00, DAkkS D-PL-15047-01-00), our measuring devices deliver high-precision measurement results that our customers benefit from in their applications. We develop, produce and calibrate our product solutions at Türkenfeld, near Munich.

In our new company video you have the opportunity to get an overview of our services, products and the people who are behind all the product developments with "Made in Germany" quality. Further reading
UV-C Radiometer for disinfection effectiveness and safety of UV-C LEDs and germicidal lamps
The X1-1-UV-3726 radiometer enables the effectiveness of UV germicidal irradiation (UVGI) to be accurately determined for both low pressure mercury (254nm) germicidal lamps and UV-C LEDs. Additionally, the device has sufficient sensitivity to detect if undesired exposure poses a photobiological safety risk to users. UVGI is a sterilization method that uses UV-C light to break down microorganisms such as viruses and bacteria by altering their DNA and RNA, rendering them unable to replicate.

The germicidal effectiveness of UV-C radiation depends on its dose (µJ / cm2) and wavelength. The dose is determined by measuring the irradiance (µW / cm2) and duration of exposure. The effectiveness of germicidal activity is wavelength dependent with a maximum around 265 nm which makes the potential germicidal efficacy of available UV-C LEDs greater than 254 nm emission Hg lamps.

The X1-1-UV-3726 radiometer measures UV-C irradiance over a very wide dynamic range to beyond 100 mW / cm² with a resolution of 0.001 µW / cm². It is calibrated for its spectral responsivity from 250 nm to 300 nm. Wavelength dependent calibration factors given in 5 nm increments are incorporated for measuring UV LEDs with known nominal wavelength. Additionally, a 254 nm calibration is included for Hg lamps as well as a general purpose 260 nm to 290 nm calibration for non-specific UV-C LEDs.

The X1-1-UV-3726 offers sufficient sensitivity to check for safety compliance and the effectiveness of personal protection equipment (PPE) in accordance with the accepted occupational exposure limit to actinic UV (ICNIRP). This requires irradiance levels to be < 0.2 µW/cm2 at 254 nm and < 0.1 µW/cm2 at 270 nm over 8 hour’s exposure. The handheld meter provides a real time display of irradiance or dose and includes a peak-hold function. The device may also be operated via its USB interface. Each meter is supplied with a traceable calibration certificate from the Gigahertz-Optik laboratory. Further reading
Gigahertz Optik gives talks at two international UV conferences
Gigahertz Optik has recently presented talks at two international conferences on UVC radiation. Both presentations are now available for post-event viewing using the following links.

At the International Ultraviolet Association’s IUVA 2021 World Congress, Gigahertz Optik’s talk “Far-UVC germicidal sources – measurement challenges and solutions” addressed the demands placed on equipment and techniques for the accurate measurement of germicidal UVC sources and in particular, far-UVC such as excimer 222nm lamps.

At the International Conference on UV LED Technologies & Applications, ICULTA 2021, the presentation “Accurate UV-C LED measurement techniques include the removal of fluorescence effects” explored the importance of considering fluorescence effects as a potential source of significant error when measuring UVC LEDs.
