The unit for photonics is responsible for the development and design of optical sensor systems. We have a distinct focus on optical measurement systems on which we can combine technologies such as opto-ASIC, diffractive optics and electro-optical carriers together with practical optical measurement technology. We carry out a mixture of long-term, research-related, development tasks along with product development and projects for companies. Underpinning these activities is our vast knowledge of electrical design, signal processing and programming, all of which are invaluable assets during prototype production.

Optical Filter on Photodiode | |
Imego has developed a concept and technique for integrating an optical filter directly onto the active surface of a photodiode. This provides numerous benefits, the system can be made smaller and lighter, assembly is simpler and manufacturing costs are less. It is also possible to apply filters with different optical characteristics on to a single photo diode chip. In other words, different parts of the multi-element photo diode can be made sensitive for light of different wavelengths.
By using our technology for integrated optical filters we have developed a sun dosimeter. This has photo diodes with optical filter for UVA radiation respectively UVB radiation. Thus, the sun dosimeter reads the actual intensity of both these wavelengths regions.
Based on the same technology, systems for other UV measurement applications can be developed. The system can be tailored in order to measure any wavelength region which is of interest in the actual application.
During the work with development of an instrument for point-of-care diagnostic we have also developed in-depth knowledge concerning fluorescent measurement in general, including suitable optical and electro-optical components. In most fluorescent measurement situations the intensity of the emitted light is extremely low. This places great demands on the incorporated components and on the optical construction as a whole. |
