sglux, founded in 2003, is a team of scientists, engineers and production, quality & logistics professionals. Together we have over 140 years of experience in the field of development, production and calibration of UV measuring components. We are united by the passion to produce simply good UV sensors – since a couple of years we do this in our own building in Berlin-Adlershof, Germany’s biggest science and technology park. Our customers appreciate our expert knowledge, our strong customer orientation and our solution expertise in the value chain of the UV measurement. Our range is a modular conception and extends from the production of SiC photodiode wafers, SiC photodiodes and SiC hybrids (TOCONs) to IoT ready sensor probes, radiometers and PTB-certified calibration standards.
This worldwide unique modular conception allows to produce customized concepts also in low quantity without additional costs or extended delivery time. Cooperating with governmental authorities and research institutes we continuously scrutinize the properties and the reliability of our products and present the results in common publications. Since 2013 our company is ISO 9001 certified. We do our calibration work according to the guidelines DAkkS 71 SD 0 025 and ISO 17025.

First SiC APDs from sglux
As part of the BMBF KMU Innovativ SiC4Flame project – FZK02P22K030 – sglux has produced the first SiC avalanche photodiodes (APDs) on 150 mm wafers together with Fraunhofer IISB Erlangen. In close cooperation with the Fraunhofer IISB team, sglux’ PhD student Felix Beier has developed a production-ready process for SiC APDs with a SACM device structure. The SiC APDs with diameters of 100 µm, 200 µm, 300 µm and 500 µm have a breakdown voltage of approximately Vbr=162.5 V and exhibit a gain m = 100 at 95% of the breakdown voltage V95%. The dark current at V95% is below 0.2 nA/mm². This means that SiC APDs have significantly better values than Si-based APDs and are also insensitive to visible radiation. Please contact us for samples for your application.

“Girl’s Day @ sglux”
The Federal Ministry for Family Affairs, Senior Citizens, Women and Youth and the Federal Ministry of Education and Research called on German companies to give schoolgirls in year 7 the opportunity to immerse themselves in their working world for a day on 25.04.24. sglux took part. Two schoolgirls from Adlershof had the challenge of designing and to build a complex LED circuit based on a 535nm LED. The picture shows that they succeeded brilliantly. We hope that the two girls will be interested in pursuing a technical education in the future.
2024
Manufacturers and installers in the field of water disinfection often need quick help in finding a replacement for specially configured UV duty sensors. We have established a system which allows us to offer customized configurations in terms of connectors, pin assignment, signal output or digital protocol, regardless of the quantity.
2023
On November 14th at the 322. PTB seminar on VUV and EUV metrology sglux’ senior scientist Niklas Papathanasiou gave a talk on “SiC-based pin-type photodiode with shallow emitter for radiation measurements below 200nm – device structure, characterisation and applications”. These photodiodes allow irradiance measurements down to 145nm as certified by the Metrological Light Source of PTB. The seminar covered the latest results from industrial applications of EUV radiation for lithography and metrology.
2023
2023 UV-REF-LED now available
A UV sensor needs to be calibrated before use. For small and only occasional quantities, this is done by our calibration laboratory. For larger quantities, this process can become impractical or uneconomical. For these cases, we provide our customers with a device with which the sensors are adjusted or calibrated. The UV-REF-LED consists of a transfer standard and a UV LED radiation source.
2023
Calibration of DVGW sensors for water disinfection: Measuring Uncertainties in UV Radiometry
At the 324th PTB seminar, titled ‘Calculation of Measurement Uncertainty – Recommendations for Practice’, our head of the calibration laboratory, Dr Niklas Papathanasiou, provided insights into the calibration of DVGW sensors for water disinfection. The seminar was held at PTB Berlin (LINK). The presentation primarily focused on the challenges of measuring UV radiation with uncertainty.
The event brought together 121 experts from various fields, including calibration and testing laboratories, authorities, and metrology institutes. The program provided insights into various facets of measurement uncertainty, from new guidelines to digitalisation.
2022
SiC photodiodes with sensitivity for wavelengths <200nm (VUV)
After three years of development work, the new SiC photodiode series “SG03” is introduced to the market. The pn junction of this new diode is manufactured using the modern ion implantation process. This process allows the depletion zone to be defined in the immediate vicinity of the chip surface. This significantly reduces the loss rate for light quanta with wavelengths below 200nm. Applications are in the field of detection of 172nm excimer sources or 185nm sources used for decomposition of fat.
2021
The sglux GmbH is founding member of the industrial association “AG-LUV UVC-Technologie e.V.” (Website currently only in German language available). Goal of this association is to refine the knowledge in the area of UVC air disinfection by means of scientific methods and, based on this new level of awareness, to elaborate guidances to the public. sglux supports its work in the area of UV dose measurement and hazard assessment.

2021
Since April 2021 sglux is member of the “DIN Deutsches Institut für Normung e. V.“, the German national organization for standardization and Germany’s ISO member body. We enrich the standards committee „light engineering“ with our knowledge skill. Our head of calibration laboratory, Dr. Niklas Papathanasiou is now active member of the board „optical radiation“ (NA 058-00-07 AA). This board works in the field of radiation physics and light engineering (DIN 5031) in particular in the area of UV radiation caused skin damage (ISO 17166, erythema action curve). Other application areas of this board are the management and improvement of the UV water disinfection standard ISO 19294 (former guideline DVGW W294) and of the UV disinfection guidelines of air (ASD-STAN/D 12/WG 4).

Special sglux SiC UV photodiode starts working on Mars
Millions of times our UV sensors provide reliable services – since February 18, 2021 even at a workplace several hundred million kilometers away: With the landing of the rover “Perseverance” on Mars, photodiodes specially developed by us for NASA started monitoring the function of the world’s first Deep UV (DUV) resonance Raman and fluorescence spectrometer UV called “Sherloc”.
2020
August 2020 Photon Collection now improved
Since founding of the company, it is almost 20 years ago, we sold millions of UV photodiodes. And each photodiode collects photons and converts it into an electrical power.
However, we discovered that the amount of photons collected with all of our UV photodiodes is quite low compared with other methods. So, we concluded to change this situation and to heavily increase the numbers of photons collected by sglux. As a result, since some weeks 10 kW photovoltaic modules at the roof of our company collect photons. This made sglux to a multi photon collecting company. At the roof we collect photons and in the house we use these photons to produce UV sensors collecting photons everywhere in the world.
2020
June 2020 The production of the sglux “UV-Sanitize” started. According to the WHO worldwide hundreds of millions hospitalized patients are affected by healthcare-associated infections (HAI). Hygienic rules and precautions are necessary to prevent patients of HAIs which also include multiple drug resistant germs. Besides chemical treatments, sterilization of surfaces by using UVC radiation from Hg low pressure or pulsed Xenon sources is widespread in hospitals and medical facilities. This is realized with irradiation chambers for smaller parts, fixed lamp systems or mobile irradiance robots to sterilize complete hospital rooms. Especially the latter systems need the collaboration with a UV sensor measuring the germicidal radiation in certain points of a room to teach the systems and the user about the UVC distribution inside a treated room. With the sglux sensor “UV-Sanitize”, treatment times and germicidal dose can be evaluated and optimized and less treated parts of rooms can be determined.
2020
May 2020 The production of the sglux “Safester UVC” started. This radiometer is an instrument for hazard assessment of artificial UVC radiation at workplaces.
