# GME ExSys 308 — service inspection and operational test HTML source: [GME ExSys 308 — service inspection and operational test](https://lasertechservice.pl/en/case-studies/gme-exsys-308-service-inspection/) Language: English Other language version: [Polski](https://lasertechservice.pl/realizacje/serwis-gme-exsys-308/), [Русский](https://lasertechservice.pl/ru/realizacje/serwis-gme-exsys-308/) > GME ExSys 308 inspection at Laser Tech Service: device and handpiece test, photographs and video. Explore the EPL system with its 308 nm UVB excimer lamp. Author: Laser Tech Service Publication date: 2026-10-01 GME ExSys 308 · German Medical Engineering A GME ExSys 308 came to Laser Tech Service for an operational check. We show the device, its handpiece and the post-service test, and explain what distinguishes this specialist phototherapy platform. ![GME ExSys 308 control panel displaying EPL IS ACTIVE](https://lasertechservice.pl/img/realizacje/gme-exsys-308/gme-exsys-308-panel-sterowania.webp) - Equipment: GME ExSys 308 - Technology: EPL · UVB 308 nm - Unit manufacture date: 16.12.2015 - Scope: Operational check ## What is the GME ExSys 308? **GME ExSys 308** is a targeted phototherapy system manufactured by German Medical Engineering GmbH in Germany. Instead of a diode laser beam, it uses a **XeCl excimer lamp** inside the applicator. The source emits UVB light at **308 nm** — hence the number in its name. The [GME ExSys 308 FDA submission](https://www.accessdata.fda.gov/cdrh_docs/pdf15/K150752.pdf) describes a touchscreen base controlling the applicator, and air cooling. UVB acts on skin immune processes and melanocyte activity. Listed uses include psoriasis and vitiligo on intact skin. This describes the model's intended use, not a treatment recommendation for an individual. ## EPL: excimer light directed at a selected area **EPL** stands for *Excimer Pulsed Light*. In the [GME manufacturer brochure](https://www.grane.cz/uploads/files/exsys-308.pdf) the system is described as a source of monochromatic UVB light. The applicator and interchangeable tips limit the exposure field; the brochure gives a maximum area of 50 × 35 mm. It is designed for targeted phototherapy, not broadband IPL or laser hair removal. The same brochure also lists alopecia areata, atopic dermatitis, mycosis fungoides and lichen planus, with a note that these uses are not approved in the USA. The intended uses of a specific version should be checked in its documentation for the relevant market. ![GME ExSys 308 rating plate with manufacturer name and date 16.12.2015](https://lasertechservice.pl/img/realizacje/gme-exsys-308/gme-exsys-308-tabliczka-znamionowa.webp) ## Identifying the unit before technical assessment This device's rating plate identifies it as **ExSys 308**, names the manufacturer as **GME German Medical Engineering GmbH**, carries the marking **Made in Germany** and gives the manufacture date as **16.12.2015**. This links the documentation to the specific unit. The manufacture date is not the date of our service. For older equipment, identifying the model has practical importance: a housing's appearance or a similar screen does not establish the light source or operating method. This account therefore relies on device markings and ExSys 308 documentation. ![GME ExSys 308 handpiece with its window illuminated during testing](https://lasertechservice.pl/img/realizacje/gme-exsys-308/gme-exsys-308-manipula-podczas-testu.webp) ## Device diagnostics and inspection The documented work covered an **operational service check of the device and a handpiece test**. The panel photograph shows “EPL IS ACTIVE”, while a separate image shows the applicator window during testing. The materials show the running system and its working part. Diagnostics must distinguish screen information from actual applicator operation. Interface values are device settings; a photograph alone is not a measurement of emitted dose. Visible illumination likewise does not establish wavelength or UVB parameters. Such assessments require appropriate procedures and measurements. With specialist equipment, servicing starts by correctly identifying the technology. This supports selection of documentation and inspection scope, and precise reporting of what was actually checked. ## GME ExSys 308 post-service test The video shows checks of the device and handpiece after servicing at Laser Tech Service. It supplements the photographs with a record of system operation.

The photographs show the active screen and working handpiece; the video documents the post-service test. This records a specific stage of work on the device. Test footage does not replace a measurement report. This account gives neither measured energy values nor an assessment of therapeutic effectiveness: it presents the documented operational check. ## Specialist equipment diagnostics Each technology requires identification of the device design and intended use. Our support scope is described on the [laser and aesthetic equipment servicing page](https://lasertechservice.pl/en/services/). We also discuss regular maintenance in the article [why professional servicing matters](https://lasertechservice.pl/en/blog/professional-aesthetic-equipment-service/). To discuss checking a specific device, [contact Laser Tech Service](https://lasertechservice.pl/en/contact/) and provide its model and a description of its operation. ## Service offerings - [Professional laser and aesthetic equipment servicing](https://lasertechservice.pl/en/services/) - [Service pricing](https://lasertechservice.pl/en/pricing/) - [Technical Service for Beauty Salon Chains and Aesthetic Clinics](https://lasertechservice.pl/en/services/service-for-salon-chains/) ## Related articles - [Why use professional aesthetic equipment servicing?](https://lasertechservice.pl/en/blog/professional-aesthetic-equipment-service/) ## Video - [GME ExSys 308 post-service test](https://www.youtube.com/embed/ytdL7NfbsFc)
