Background Optics Research
- Department of Physics at the University of Joensuu has concentrated to optics research since the establishent of the Department in 1970- From holography to diffractive optics
Spectral Color Research- Group started in the middle of 1980’s- Joint group of the Department of Physics and
the Department of Computer Science• Long-term research background and internationally known groups
Industrial cooperation expanded • Need for the research and business service center
• InFotonics Center started on September 2003

Wave-optical engineering
A new electron beam lithography system Leica EBPG5000plusES will be installed June-July, 2006. The system allows high speed electron beam patterning at 150mm x 150 mm maximum.
Overall positioning accuracy is 30 - 60 nm depending on beam energy and main field size. Positioning within 400 um field size is 15 nm.
Smallest patterned linewidth at electron beam resist is 10 nm.
The system takes into account the proximity effects, which will improve patterning accuracy in cases where complex patterns with variable sizes and areas are patterned together.
Wave-optical engineering
New reactive ion etching systems Plasmalab 100 and Plasmalab 80plus allowing fabrication of complex diffractive optical structures, such as deep structures at fused silica, waveguides, sub-micron scale patterns for metal masking technology, and multilevel diffractive patterns on fused silica for diffraction and light wavefront modulation.
Holographic lithography system allowing efficient fabrication of 100 mm large scale linear gratings and grid-like patterns down to linewidth of 200 nm.
Applications: Spectral color research
Computer vision, pattern recognition, neural computation, classification
Industrial quality control Color calibration of display units Software for spectral measuring instruments Color analysis of objects with cultural history value Spectral analysis of fluorescent materials Applications of telemedicine (e.g. skin color) Watermarking of digital color images
