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.
UV measurement
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.
Fluorescent measurements
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.
