The FX DUV Fluorescence Detector is a small size, light weight, lower power system focused on detection and classification of ultra-trace concentration of organic contaminants on surfaces such as high-performance optical components, semiconductors and other manufactured surfaces susceptible to ultra-trace levels of contamination.
The FX has a working distance of 100mm and a +-5mm depth of focus, making it suitable for a wide range of in process surface contamination inspections and measurements.
A major driving motivation for FX is the ability to detect chemical contaminants of critical component surfaces as part of QA processes.
A second driving motivation for FX is real-time detection of contaminants in liquids or water.
A third driving motivation is the ability to detect biological material on surfaces or in water. This is not possible with other methods, including 1064nm, 785nm or 532nm Raman methods.
The FX includes:
- Deep UV laser and controller
- 6-band deep UV detector with 8-decade dynamic range

Trace Contamination Detection
Deep UV fluorescence detection offers significant advantages for organic trace surface contamination detection. With laser based detection, the limit of detection can be well under 1 nanogram per square cm. Through the use of multiple detection bands, multiple contaminants can be detected.
Trace Explosives Detection
Photon Systems focuses on explosives detection using the combination of deep UV autofluorescence and Raman spectroscopy using deep UV sources that enable compact, low power consuming devices
Cleaning Validation
Pharmaceutical production, food culture industry and other processes that produce products requiring documented high levels of purity and freedom from contamination.
Optical Scattering
Photon Systems has developed a unique instrument to measure the deep UV non-specular scatter properties of optical elements, including gratings, mirrors, filters, etc.
