Photon - Model MOSAIC -DUV Fluorescence Mapper
The MOSAIC DUV Fluorescence Mapper 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. A major driving motivation for MOSAIC is the ability to spatially map or image chemical contaminants of critical component surfaces as part of QA processes.
A second driving motivation for MOSAIC is real-time detection of contaminants in liquids or water.
A third driving motivation is the ability to detect and/or map biological material on surfaces or in water. This is not possible with other methods, including 1064nm, 785nm or 532nm Raman methods.
The MOSAIC includes:
- Deep UV laser and controller
- 6-band deep UV detector with 8-decade dynamic range
- Automated XYZ mapping stage
- Context imaging camera
